This yields an exact negative impression of the channel, offering numerous advantages. &lt;\\\/p&gt;\\n&lt;ul&gt;\\n&lt;li&gt;Our replication material is characterized by low adhesion, allowing the impression to be easily removed even from very long channels (up to several cm) without damaging the spinneret or the impression itself.&lt;\\\/li&gt;\\n&lt;li&gt;The shrinkage of our replication material is very low, allowing geometries and angles to be reproduced with high precision.&lt;\\\/li&gt;\\n&lt;li&gt;The analysis of surface morphology is performed using optical &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/methoden\\\/surface-analysis-and-microscopy\\\/\\&quot;&gt;microscopy&lt;\\\/a&gt; (Fig. 1) or &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/methoden\\\/surface-analysis-and-microscopy\\\/\\&quot;&gt;scanning electron microscopy (SEM)&lt;\\\/a&gt;, preserving structures even in the sub-\\u00b5m range (Fig. 2).&lt;\\\/li&gt;\\n&lt;li&gt;Surface roughness and channel structure are examined at high resolution using SEM.&lt;\\\/li&gt;\\n&lt;li&gt;Our replication material has a short curing time (a few minutes), thus keeping the downtime of a spinneret correspondingly short.

Nevertheless, the corresponding material data are often only known at room temperature \\u2013 but not at low or high temperatures, as they occur, for example, when used in &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/industries\\\/automotive\\\/\\&quot;&gt;automotive components&lt;\\\/a&gt;. &lt;\\\/p&gt;\\n&lt;h5&gt;Solution&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;We can determine mechanical parameters of plastic materials over a very wide temperature range. For this purpose, a temperature chamber is used, which can be cooled down to temperatures as low as -80 \\u00b0C by means of liquid nitrogen cooling. On the other hand, high temperatures up to 200 \\u00b0C can also be reached by means of a forced air heater. This temperature chamber is operated in combination with a universal tensile testing machine (maximum tensile force 10 kN) and special clamping tools. The overall system thus enables the performance of various mechanical tests such as tensile, compression, and bending tests as a function of temperature.    &lt;\\\/p&gt;\\n&lt;ul&gt;\\n&lt;li&gt;&lt;strong&gt;Industries:&lt;\\\/strong&gt; &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/industries\\\/fibers-textiles\\\/\\&quot;&gt;Fiber Manufacturers&lt;\\\/a&gt;, Weaving Mills, &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/test-standards\\\/\\&quot;&gt;Automotive Suppliers&lt;\\\/a&gt;&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Analysis Objectives:&lt;\\\/strong&gt; Mechanical data under temperature&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Materials:&lt;\\\/strong&gt; &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/industries\\\/\\&quot;&gt;Fibers&lt;\\\/a&gt;, &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/industries\\\/\\&quot;&gt;Fabrics&lt;\\\/a&gt;&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Analysis Method:&lt;\\\/strong&gt; &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/industries\\\/fibers-textiles\\\/\\&quot;&gt;Tensile Test&lt;\\\/a&gt;&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5 class=\\&quot;p1\\&quot;&gt;Example \\u2013 Chemical Fiber Fabric (Temperature -40 \\u00b0C)&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;The adjacent diagram shows the stress-strain behavior of a chemical fiber fabric at three different measurement temperatures.

While filters retain many \\u2013 especially larger \\u2013 particles, smaller or gel-like contaminants still pass through the filter. If a large amount of particles is retained, this leads to a premature pressure increase, so the filter must be changed prematurely. Although the polymer is cleaned by the filter, the actual cause of the contaminants remains unknown.   &lt;\\\/p&gt;\\n&lt;h5&gt;Solution&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;&lt;strong&gt;Analytik Service Obernburg&lt;\\\/strong&gt; employs microscopic techniques on cross-sections to trace the filter residues.&lt;\\\/p&gt;\\n&lt;ul&gt;\\n&lt;li&gt;&lt;strong&gt;&lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/industries\\\/\\&quot;&gt;Industries&lt;\\\/a&gt;:&lt;\\\/strong&gt; &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/industries\\\/\\&quot;&gt;Chemical Fiber&lt;\\\/a&gt;, &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/branchen\\\/polymers\\\/\\&quot;&gt;Plastics Processors&lt;\\\/a&gt;&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Analysis Objectives:&lt;\\\/strong&gt; Process Optimization, &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/services\\\/product-analysis\\\/\\&quot;&gt;Product Optimization&lt;\\\/a&gt;, &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/services\\\/failure-analysis\\\/\\&quot;&gt;Damage Case Analysis&lt;\\\/a&gt;&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Materials:&lt;\\\/strong&gt; Filter Screens, Contaminants, &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/branchen\\\/polymers\\\/polymer-characterization\\\/\\&quot;&gt;Polymers&lt;\\\/a&gt;&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Analysis Methods: &lt;\\\/strong&gt;Light Microscopy, Scanning Electron Microscopy (SEM-EDX)&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Supplementary Methods:&lt;\\\/strong&gt; FTIR Spectroscopy&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Related Questions: &lt;\\\/strong&gt;Solids in Liquids, Inclusions&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5 class=\\&quot;p1\\&quot;&gt;Example \\u2013 Light Microscopic Analysis&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;After polishing the cross-section, the filter wires are visible under reflected light, but the residues are poorly discernible (Fig. 1). By using polarized light, the intrinsic color of the residues is obtained. Soot appears black here. With the help of fluorescence, degraded polymer can often be detected, which, with sufficient pressure build-up, can be forced through the filter openings. The color can be correlated with the extent of the damage.    &lt;\\\/p&gt;\\n&lt;h5 class=\\&quot;p1\\&quot;&gt;Example \\u2013 SEM\\\/EDX Material Identification&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p2\\&quot;&gt;Material identification of the residues is performed using X-ray analytics (EDX) spectra in the scanning electron microscope (SEM). This is sufficient for simple residues, e.g., mineral contaminants. If the structure is more complex, elemental distribution maps can help understand the composition. In the above case (Fig. 2), the residue originated from the wall of the reaction vessel in which the &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/branchen\\\/polymers\\\/polymer-characterization\\\/\\&quot;&gt;polymer&lt;\\\/a&gt; was synthesized, with different &lt;a href=\\&quot;https:\\\/\\\/aso-labor.de\\\/en\\\/branchen\\\/polymers\\\/polymer-characterization\\\/\\&quot;&gt;polymer types&lt;\\\/a&gt; being produced consecutively in the same vessel.

To detect possible changes without lengthy ongoing tests, it is necessary to simulate wear in an accelerated manner and subsequently examine the abraded samples for optical changes.&lt;\\\/p&gt;\\n&lt;h5&gt;Solution&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;A Martindale testing device is used to simulate abrasion and wear of technical textiles. The abrasion resistance test is carried out according to DIN EN ISO 12947, on which common automotive standards such as BMW GS 97034-6 Procedure B or VW 50105 are based. In this process, the fixed flat sample is subjected to stress by an abrasive fabric under defined parameters (pressure, movement, frequency, medium) for a defined period.  &lt;\\\/p&gt;\\n&lt;ul&gt;\\n&lt;li&gt;&lt;strong&gt;&lt;strong&gt;Industries: &lt;\\\/strong&gt;&lt;\\\/strong&gt;Automotive Suppliers, Textile&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;&lt;strong&gt;Analysis Objectives: &lt;\\\/strong&gt;&lt;\\\/strong&gt;Initial Sample Release Inspection, Verification against Abrasion and Wear&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Materials: &lt;\\\/strong&gt;Fabrics, Plastic Finished Parts, Painted Components&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Analytical Methods: &lt;\\\/strong&gt;Martindale&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Complementary Methods: &lt;\\\/strong&gt;Color Measurement, Grey Scale ABREX, Crockmeter, Taber&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Results&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;After the stress test, the evaluation is performed according to the specified standards. As a rule, the grey scale according to DIN EN 20105-A02 and DIN EN 20105-A03 is also evaluated. &lt;\\\/p&gt;\\n&lt;h5 class=\\&quot;p1\\&quot;&gt;&lt;b&gt;Advantages&lt;\\\/b&gt;&lt;b&gt;&lt;\\\/b&gt;&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;Abrasion and wear testing devices make it possible to investigate wear on technical textiles in the laboratory. Additionally, by simultaneously exposing them to various media, their influence on abrasion and wear behavior can be simulated in an accelerated manner. Based on the results of these tests, the suitability and quality of materials can be assessed.  &lt;\\\/p&gt;\\n&quot;,&quot;item_icon&quot;:{&quot;value&quot;:&quot;far fa-file-pdf&quot;,&quot;library&quot;:&quot;fa-regular&quot;},&quot;_id&quot;:&quot;650ed06&quot;,&quot;content_type&quot;:&quot;toggle-content&quot;,&quot;saved_section&quot;:null,&quot;saved_template&quot;:null,&quot;toggle_custom_id&quot;:&quot;&quot;},{&quot;toggle_title&quot;:&quot;Silicone Coating of Fabrics&quot;,&quot;toggle_content&quot;:&quot;&lt;h4 class=\\&quot;p1\\&quot;&gt;Silicone Coating of Fabrics \\u2013 Analysis &amp; Durability Testing&lt;\\\/h4&gt;\\n&lt;h5&gt;Problem Statement&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;Fabrics are often coated with silicone for protection or to increase gas tightness. The coating thickness is typically determined by the applied weight. However, this area weight only provides an average value and says nothing about the local distribution or adhesion of the coating.  &lt;\\\/p&gt;\\n&lt;h5&gt;Solution&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;In such cases, &lt;strong&gt;Analytical Services Obernburg&lt;\\\/strong&gt; employs a special imaging mode of scanning electron microscopy (SEM). In this &lt;\\\/p&gt;\\n&lt;ul&gt;\\n&lt;li&gt;&lt;strong&gt;Industries: &lt;\\\/strong&gt;Fabric Manufacturers, Fiber Manufacturers&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;&lt;strong&gt;&lt;strong&gt;Analysis Objectives: &lt;\\\/strong&gt;&lt;\\\/strong&gt;&lt;\\\/strong&gt;Coating Thickness, Penetration Depth&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Materials: &lt;\\\/strong&gt;Coated Fabrics&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Analytical Methods: &lt;\\\/strong&gt;Scanning Electron Microscopy (SEM\\\/EDX)&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;section&gt;\\n&lt;p&gt;Fig. 1 (left) shows the coated front side of the fabric. The coating thickness on the fabric crests is so thin that the darker-appearing fibers are clearly visible through the coating. Thus, it offers only rather limited protection for the crests. On the other hand, the silicone has accumulated in the depressions of the fabric, forming the bright area. On the reverse side of the fabric (Fig. 1, right), a small amount of coating material (brightly illuminated) that has penetrated through the fabric can be observed at the intersection points between warp and weft threads.     &lt;\\\/p&gt;\\n&lt;p&gt;In cross-section (Fig. 2), the coating thickness can be precisely measured at every point. As expected from the surface images (Fig. 1), the coating is completely absent from the fabric crests. Furthermore, illustrative information is obtained about the penetration depth of the coating into the fiber bundle (here 1\\u20132 filament layers) and thus about the quality of wetting and the resulting adhesion properties.   &lt;\\\/p&gt;\\n&lt;p&gt;Possible defects within the coating or between the fiber and the coating can also be investigated in this manner. Additionally, the local elemental composition of the coating can be determined via X-ray microanalysis (SEM-EDX), making inhomogeneities (e.g., particle inclusions) detectable. &lt;\\\/p&gt;\\n&lt;h5&gt;Advantages&lt;\\\/h5&gt;\\n&lt;p&gt;The described method allows for precise visualization and analysis of the layer structure, possible defects, and the measurement of local layer thickness. Furthermore, the adhesion mechanism can be further investigated by examining the penetration depth of the coating into the fiber bundle. The method is also suitable for other types of coatings (e.g., PVC) or for the analysis of laminates.  &lt;\\\/p&gt;\\n&lt;\\\/section&gt;\\n&lt;p&gt;&lt;img class=\\&quot;alignnone wp-image-35566 size-full\\&quot; src=\\&quot;https:\\\/\\\/aso-labor.de\\\/wp-content\\\/uploads\\\/2025\\\/04\\\/Abb-1-Vorder-links-und-Rueckseite-rechts-eines-einseitig-mit-Silikonbeschichteten-Airbag-Gewebes.jpeg\\&quot; alt=\\&quot;\\&quot; width=\\&quot;731\\&quot; height=\\&quot;299\\&quot;&gt;&lt;\\\/p&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;&lt;strong&gt;Fig. 1: Front (left) and reverse (right) sides of a single-sided silicone-coated airbag fabric.&lt;\\\/strong&gt;&lt;\\\/p&gt;\\n&lt;p&gt;&lt;img class=\\&quot;alignnone wp-image-35567 size-full\\&quot; src=\\&quot;https:\\\/\\\/aso-labor.de\\\/wp-content\\\/uploads\\\/2025\\\/04\\\/Abb.-2-Querschnitt-durch-ein-einseitig-mit-Silikon-beschichtetes-Gewebe.jpeg\\&quot; alt=\\&quot;\\&quot; width=\\&quot;464\\&quot; height=\\&quot;335\\&quot;&gt;&lt;\\\/p&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;&lt;strong&gt;Fig. 2: Cross-section of a single-sided silicone-coated fabric &lt;\\\/strong&gt;&lt;\\\/p&gt;\\n&quot;,&quot;item_icon&quot;:{&quot;value&quot;:&quot;far fa-file-pdf&quot;,&quot;library&quot;:&quot;fa-regular&quot;},&quot;_id&quot;:&quot;9deba98&quot;,&quot;content_type&quot;:&quot;toggle-content&quot;,&quot;saved_section&quot;:null,&quot;saved_template&quot;:null,&quot;toggle_custom_id&quot;:&quot;&quot;},{&quot;toggle_title&quot;:&quot;Cleaning Cloth with Stains&quot;,&quot;toggle_content&quot;:&quot;&lt;h4 class=\\&quot;p1\\&quot;&gt;Cleaning Performance Test&lt;\\\/h4&gt;\\n&lt;h5&gt;Problem Statement&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;Special cloths, already impregnated with a cleaning and care product, are often used for surface cleaning. Sealed in foil, these are only removed shortly before use. In one instance, individual cleaning cloths showed distinct dark spots immediately after opening the packaging. It was suspected that these could be grease stains.   &lt;\\\/p&gt;\\n&lt;h5&gt;Solution&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;Analytik Service Obernburg utilizes microscopic techniques for the analysis of such stains. The filamentous structure of the very dark contamination clearly indicates a fungal infestation. Consultation with the client revealed that the cleaning medium had recently been changed to a new product, and the new medium no longer contained alcohol. To prevent this, a cleaning solution with fungicidal agents or subsequent sterilization was recommended.   &lt;\\\/p&gt;\\n&lt;ul&gt;\\n&lt;li&gt;&lt;strong&gt;Industries: &lt;\\\/strong&gt;Automotive Suppliers, Chemistry, Electronics, Paints and Coatings, Plastics Processors, Mechanical Engineering, Medical Technology&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;&lt;strong&gt;&lt;strong&gt;Analysis Objectives: &lt;\\\/strong&gt;&lt;\\\/strong&gt;&lt;\\\/strong&gt;Failure Analysis&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Materials: &lt;\\\/strong&gt;Contaminants of all types&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Analytical Methods: &lt;\\\/strong&gt;Light Microscopy, Scanning Electron Microscope&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Complementary Methods:&lt;\\\/strong&gt; IR Spectroscopy&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Related Issues:&lt;\\\/strong&gt; Inclusions&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;section&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;Additionally, individual particles were observed between the large dark spots, which also needed to be characterized. For this purpose, this area of the cloth was analyzed using a scanning electron microscope. This method allows for the elemental analysis of the smallest areas (Fig. 3), in addition to displaying topography and material differences (Fig. 2).  &lt;\\\/p&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;Based on their composition, the particles are attributable to mineral contaminants and likely represent subsequent contamination due to handling, which occurred when the cloth was removed from its packaging.&lt;\\\/p&gt;\\n&lt;h5&gt;Advantages&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;The combination of light and electron microscopy is an effective method for stain investigation, provided the images obtained are expertly interpreted.

In conjunction with X-ray microanalysis (EDX), it also allows for the characterization of the elemental composition of the smallest defect areas.  &lt;\\\/p&gt;\\n&lt;ul&gt;\\n&lt;li&gt;&lt;strong&gt;&lt;strong&gt;Industries: &lt;\\\/strong&gt;&lt;\\\/strong&gt;Fiber Manufacturers, Weaving Mills, Coaters&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;&lt;strong&gt;&lt;strong&gt;Analysis Objectives: &lt;\\\/strong&gt;&lt;\\\/strong&gt;&lt;\\\/strong&gt;Failure Analysis&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Materials: &lt;\\\/strong&gt;Fabrics&lt;\\\/li&gt;\\n&lt;li&gt;&lt;strong&gt;Analytical Methods: &lt;\\\/strong&gt;Scanning Electron Microscopy (SEM-EDX), Light Microscopy&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;section&gt;\\n&lt;h5&gt;Advantages&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;With the aid of scanning electron microscopy, defects in textile fabrics can be investigated in various ways. This allows for quick acquisition of information about their topography and elemental composition. The results obtained often allow conclusions to be drawn about the root cause of the defect, from which solutions for future defect prevention can be derived.  &lt;\\\/p&gt;\\n&lt;h5 class=\\&quot;p1\\&quot;&gt;Example \\u2013 Fabric with Dark Stripe&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;The dark stripe in the fabric was caused by inorganic contamination in the form of tiny particles (brightly illuminated in the material contrast image). This contamination affects only one thread; the weft threads are not affected. Therefore, it can be assumed that the contamination was applied to the thread before the weaving process. Precise elemental analysis of the contamination (EDX) provides information about the composition of the particles. Accordingly, rust particles (Fe\\\/O) are responsible for the discoloration.    &lt;\\\/p&gt;\\n&lt;h5 class=\\&quot;p1\\&quot;&gt;Example \\u2013 Irregular Surface on Coated Fabric&lt;\\\/h5&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;A PVC-coated fabric sample exhibits pock-like elevations on its surface. A cross-section was prepared through one of the defects and examined under a scanning electron microscope. A clear void within the PVC coating is visible. Simultaneously, PVC residues are found on the fabric, thus ruling out poor wetting of the fabric as the cause. Furthermore, the material contrast image allows for the study of PVC penetration into the fiber bundle, providing insights into the existing adhesion mechanisms.    &lt;\\\/p&gt;\\n&lt;\\\/section&gt;\\n&lt;p&gt;&lt;img class=\\&quot;alignnone wp-image-35575 size-full\\&quot; src=\\&quot;https:\\\/\\\/aso-labor.de\\\/wp-content\\\/uploads\\\/2025\\\/04\\\/Abb.-1-Beispiel-Gewebe-mit-dunklem-Streifen.jpeg\\&quot; alt=\\&quot;\\&quot; width=\\&quot;711\\&quot; height=\\&quot;510\\&quot;&gt;&lt;\\\/p&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;&lt;strong&gt;Fig. 1 Example \\u2013 Fabric with Dark Stripe &lt;\\\/strong&gt;&lt;\\\/p&gt;\\n&lt;p&gt;&lt;img class=\\&quot;alignnone wp-image-35574 size-full\\&quot; src=\\&quot;https:\\\/\\\/aso-labor.de\\\/wp-content\\\/uploads\\\/2025\\\/04\\\/Rasterelektronenmikroskopische-Aufnahmen-des-Topografiekontrasts.jpeg\\&quot; alt=\\&quot;\\&quot; width=\\&quot;903\\&quot; height=\\&quot;323\\&quot;&gt;&lt;\\\/p&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;&lt;strong&gt;Fig. 2: Scanning electron micrographs of the topography contrast (left) and material contrast (right) of a PVC-coated fabric in cross-section. &lt;\\\/strong&gt;&lt;\\\/p&gt;\\n&quot;,&quot;item_icon&quot;:{&quot;value&quot;:&quot;far fa-file-pdf&quot;,&quot;library&quot;:&quot;fa-regular&quot;},&quot;_id&quot;:&quot;6d29514&quot;,&quot;content_type&quot;:&quot;toggle-content&quot;,&quot;saved_section&quot;:null,&quot;saved_template&quot;:null,&quot;toggle_custom_id&quot;:&quot;&quot;},{&quot;toggle_title&quot;:&quot;Determination of Spin Finish&quot;,&quot;toggle_content&quot;:&quot;&lt;h4 class=\\&quot;p1\\&quot;&gt;Analyses on Yarns &amp; Textiles&lt;\\\/h4&gt;\\n&lt;h5&gt;Introduction&lt;\\\/h5&gt;\\n&lt;p&gt;&lt;span style=\\&quot;font-weight: 400;\\&quot;&gt;Spin finish, also known as spin oil or spinning auxiliary, is an essential component in the production of yarns and subsequently fabrics for technical or textile applications. These are liquid or pasty formulations applied to the surface of fibers to improve their physical properties and thus facilitate the processing step. The determination of spin finish is therefore crucial for the quality and efficiency of the product and subsequent processing steps.  &lt;\\\/span&gt;&lt;\\\/p&gt;\\n&lt;h5&gt;Methods&lt;\\\/h5&gt;\\n&lt;p&gt;&lt;span style=\\&quot;font-weight: 400;\\&quot;&gt;There are various methods for determining spin finish, which can be used depending on requirements and available resources:&lt;\\\/span&gt;&lt;\\\/p&gt;\\n&lt;ol&gt;\\n&lt;li style=\\&quot;font-weight: 400;\\&quot; aria-level=\\&quot;1\\&quot;&gt;&lt;b&gt;Wet Chemical Extraction Method&lt;\\\/b&gt;&lt;span style=\\&quot;font-weight: 400;\\&quot;&gt;: This traditional gravimetric method involves the extraction of the spin finish from the fibers with a suitable solvent and the subsequent gravimetric determination of the extract.

properties such as the modulus of elasticity, tensile strength, or elongation at break show a strong temperature dependence in plastic materials. Nevertheless, the corresponding material data are often only known at room temperature \u2013 but not at low or high temperatures, as they occur, for example, when used in <a href=\"https:\/\/aso-labor.de\/en\/industries\/automotive\/\">automotive components<\/a>. <\/p>\n<h5>Solution<\/h5>\n<p class=\"p1\">We can determine mechanical parameters of plastic materials over a very wide temperature range. For this purpose, a temperature chamber is used, which can be cooled down to temperatures as low as -80 \u00b0C by means of liquid nitrogen cooling. On the other hand, high temperatures up to 200 \u00b0C can also be reached by means of a forced air heater. This temperature chamber is operated in combination with a universal tensile testing machine (maximum tensile force 10 kN) and special clamping tools. The overall system thus enables the performance of various mechanical tests such as tensile, compression, and bending tests as a function of temperature.    <\/p>\n<ul>\n<li><strong>Industries:<\/strong> <a href=\"https:\/\/aso-labor.de\/en\/industries\/fibers-textiles\/\">Fiber Manufacturers<\/a>, Weaving Mills, <a href=\"https:\/\/aso-labor.de\/en\/test-standards\/\">Automotive Suppliers<\/a><\/li>\n<li><strong>Analysis Objectives:<\/strong> Mechanical data under temperature<\/li>\n<li><strong>Materials:<\/strong> <a href=\"https:\/\/aso-labor.de\/en\/industries\/\">Fibers<\/a>, <a href=\"https:\/\/aso-labor.de\/en\/industries\/\">Fabrics<\/a><\/li>\n<li><strong>Analysis Method:<\/strong> <a href=\"https:\/\/aso-labor.de\/en\/industries\/fibers-textiles\/\">Tensile Test<\/a><\/li>\n<\/ul>\n<h5 class=\"p1\">Example \u2013 Chemical Fiber Fabric (Temperature -40 \u00b0C)<\/h5>\n<p class=\"p1\">The adjacent diagram shows the stress-strain behavior of a chemical fiber fabric at three different measurement temperatures.

The knowledge gained often allows conclusions to be drawn, from which targeted solution approaches for future error prevention can be derived.   <\/p>\n<\/div><\/div><div class=\"elementor-widget-cmsmasters-toggles__item\"><h3 id=\"elementor-tab-title-7244\" class=\"elementor-widget-cmsmasters-toggles__title\" data-tab=\"4\" aria-expanded=\"false\" aria-controls=\"elementor-widget-cmsmasters-toggles__content-7244\" tabindex=\"0\"><a class=\"elementor-widget-cmsmasters-toggles__title-link cmsmasters_enable_trigger_icon\" href=\"#\" tabindex=\"-1\"><span class=\"elementor-widget-cmsmasters-toggles__item-icon\"><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-far-file-pdf\" viewbox=\"0 0 384 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M369.9 97.9L286 14C277 5 264.8-.1 252.1-.1H48C21.5 0 0 21.5 0 48v416c0 26.5 21.5 48 48 48h288c26.5 0 48-21.5 48-48V131.9c0-12.7-5.1-25-14.1-34zM332.1 128H256V51.9l76.1 76.1zM48 464V48h160v104c0 13.3 10.7 24 24 24h104v288H48zm250.2-143.7c-12.2-12-47-8.7-64.4-6.5-17.2-10.5-28.7-25-36.8-46.3 3.9-16.1 10.1-40.6 5.4-56-4.2-26.2-37.8-23.6-42.6-5.9-4.4 16.1-.4 38.5 7 67.1-10 23.9-24.9 56-35.4 74.4-20 10.3-47 26.2-51 46.2-3.3 15.8 26 55.2 76.1-31.2 22.4-7.4 46.8-16.5 68.4-20.1 18.9 10.2 41 17 55.8 17 25.5 0 28-28.2 17.5-38.7zm-198.1 77.8c5.1-13.7 24.5-29.5 30.4-35-19 30.3-30.4 35.7-30.4 35zm81.6-190.6c7.4 0 6.7 32.1 1.8 40.8-4.4-13.9-4.3-40.8-1.8-40.8zm-24.4 136.6c9.7-16.9 18-37 24.7-54.7 8.3 15.1 18.9 27.2 30.1 35.5-20.8 4.3-38.9 13.1-54.8 19.2zm131.6-5s-5 6-37.3-7.8c35.1-2.6 40.9 5.4 37.3 7.8z\"><\/path><\/svg><\/span><span class=\"elementor-widget-cmsmasters-toggles__title-text\">Spin Filter Analysis<\/span><\/a><span class=\"elementor-widget-cmsmasters-toggles__trigger\"><span class=\"elementor-widget-cmsmasters-toggles__trigger-closed\"><i aria-hidden=\"true\" aria-label=\"Closed\" class=\"cmsmsdemo-icon- cmsms-demo-icon-plus\"><\/i><\/span><span class=\"elementor-widget-cmsmasters-toggles__trigger-opened\"><i aria-hidden=\"true\" aria-label=\"Opened\" class=\"cmsmsdemo-icon- cmsms-demo-icon-minus\"><\/i><\/span><\/span><\/h3><div id=\"elementor-widget-cmsmasters-toggles__content-7244\" class=\"elementor-widget-cmsmasters-toggles__content elementor-clearfix\" data-tab=\"4\"><h4 class=\"p1\">Learning from Filter Residues<\/h4>\n<h5>Problem Statement<\/h5>\n<p><strong>Contaminants in the polymer<\/strong> repeatedly lead to spinning problems in chemical fiber production. While filters retain many \u2013 especially larger \u2013 particles, smaller or gel-like contaminants still pass through the filter. If a large amount of particles is retained, this leads to a premature pressure increase, so the filter must be changed prematurely. Although the polymer is cleaned by the filter, the actual cause of the contaminants remains unknown.   <\/p>\n<h5>Solution<\/h5>\n<p class=\"p1\"><strong>Analytik Service Obernburg<\/strong> employs microscopic techniques on cross-sections to trace the filter residues.<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/aso-labor.de\/en\/industries\/\">Industries<\/a>:<\/strong> <a href=\"https:\/\/aso-labor.de\/en\/industries\/\">Chemical Fiber<\/a>, <a href=\"https:\/\/aso-labor.de\/en\/branchen\/polymers\/\">Plastics Processors<\/a><\/li>\n<li><strong>Analysis Objectives:<\/strong> Process Optimization, <a href=\"https:\/\/aso-labor.de\/en\/services\/product-analysis\/\">Product Optimization<\/a>, <a href=\"https:\/\/aso-labor.de\/en\/services\/failure-analysis\/\">Damage Case Analysis<\/a><\/li>\n<li><strong>Materials:<\/strong> Filter Screens, Contaminants, <a href=\"https:\/\/aso-labor.de\/en\/branchen\/polymers\/polymer-characterization\/\">Polymers<\/a><\/li>\n<li><strong>Analysis Methods: <\/strong>Light Microscopy, Scanning Electron Microscopy (SEM-EDX)<\/li>\n<li><strong>Supplementary Methods:<\/strong> FTIR Spectroscopy<\/li>\n<li><strong>Related Questions: <\/strong>Solids in Liquids, Inclusions<\/li>\n<\/ul>\n<h5 class=\"p1\">Example \u2013 Light Microscopic Analysis<\/h5>\n<p class=\"p1\">After polishing the cross-section, the filter wires are visible under reflected light, but the residues are poorly discernible (Fig. 1). By using polarized light, the intrinsic color of the residues is obtained. Soot appears black here. With the help of fluorescence, degraded polymer can often be detected, which, with sufficient pressure build-up, can be forced through the filter openings. The color can be correlated with the extent of the damage.    <\/p>\n<h5 class=\"p1\">Example \u2013 SEM\/EDX Material Identification<\/h5>\n<p class=\"p2\">Material identification of the residues is performed using X-ray analytics (EDX) spectra in the scanning electron microscope (SEM). This is sufficient for simple residues, e.g., mineral contaminants. If the structure is more complex, elemental distribution maps can help understand the composition. In the above case (Fig. 2), the residue originated from the wall of the reaction vessel in which the <a href=\"https:\/\/aso-labor.de\/en\/branchen\/polymers\/polymer-characterization\/\">polymer<\/a> was synthesized, with different <a href=\"https:\/\/aso-labor.de\/en\/branchen\/polymers\/polymer-characterization\/\">polymer types<\/a> being produced consecutively in the same vessel. Manganese phosphate or antimony are typical catalysts in <a href=\"https:\/\/aso-labor.de\/en\/industries\/\">polyester production<\/a>, while titanium dioxide is used as a white pigment. <\/p>\n<h5 class=\"p1\"><b>Advantages<\/b><b><\/b><\/h5>\n<p class=\"p2\">The described method allows for the visualization and identification of filter residues. This enables the analysis of causes for contaminants and the optimization of processes. Filtration concentrates the contaminants. The method is also suitable, in a modified form, for separating and examining solids from liquids.

Additives and specific manufacturing conditions usually prevent the system from demixing. Despite having the same composition, batch B was unstable, meaning the oil droplets enlarged and, after a prolonged resting period of several days, settled to the bottom as large drops (Fig. 1). This demixing led to problems in further processing.<\/p>\n<h5>Solution<\/h5>\n<p class=\"p1\">At Analytik Service Obernburg, freshly prepared batches A and B were comparatively analyzed using a laser particle size analyzer (Fig. 2).<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/aso-labor.de\/en\/industries\/\">Industries<\/a>: <\/strong>Chemistry, Paint Manufacturers, Fiber Manufacturers, Medical Technology<\/li>\n<li><strong><strong>Analysis Objectives: <\/strong><\/strong>Process Optimization, Failure Analysis<\/li>\n<li><strong>Materials: <\/strong>Emulsions<\/li>\n<li><strong>Analytical Methods: <\/strong>Laser Particle Sizer<\/li>\n<li><strong>Complementary Methods: <\/strong>Light Microscopy, IR Spectroscopy, NMR Spectroscopy<\/li>\n<li><strong><strong>Related Issues: <\/strong><\/strong>Particle Size Distribution<\/li>\n<\/ul>\n<h5 class=\"p1\">Results<\/h5>\n<p class=\"p1\">The poor sample (B), in its as-received state, shows a very broad droplet size distribution (red curve) with a pronounced maximum at 20 \u00b5m. If this emulsion is measured with activated ultrasound, the droplets can be reduced in size, forming a stable distribution with a maximum at 2 \u00b5m (yellow curve). The good (stable) emulsion shows the same distribution with and without ultrasound (green curve). The main proportion of droplets in the distribution is significantly below 1 \u00b5m, with a small secondary maximum at 2 \u00b5m.   <\/p>\n<p class=\"p1\">In a further step, various changes were made to the manufacturing process, and the corresponding emulsions were measured for droplet size using ultrasound. The results are shown in Fig. 3. A significant variation in the relative proportions of droplets larger than 1 \u00b5m can be observed.<\/p>\n<p class=\"p1\">If the various emulsions are stored for several days, separation and the formation of distinct layers can be observed (Fig. 4). The height of these layers corresponds to the expectations derived from the droplet size distribution measurement results. <\/p>\n<h5 class=\"p1\"><b>Advantages<\/b><b><\/b><\/h5>\n<p class=\"p1\">The described method allows for the quantification of an emulsion\u2019s quality long before demixing occurs. Furthermore, the method is suitable for measuring the size distribution of particles in powders or dispersions. <\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-35552

degree of wear due to friction and abrasion. This can lead, for example, to undesirable color changes or even fabric damage. Therefore, wear tests are stipulated for such components as part of the initial sample release inspection. Passing these tests ensures that no negative changes occur within the vehicle\u2019s service life. To detect possible changes without lengthy ongoing tests, it is necessary to simulate wear in an accelerated manner and subsequently examine the abraded samples for optical changes.<\/p>\n<h5>Solution<\/h5>\n<p class=\"p1\">A Martindale testing device is used to simulate abrasion and wear of technical textiles. The abrasion resistance test is carried out according to DIN EN ISO 12947, on which common automotive standards such as BMW GS 97034-6 Procedure B or VW 50105 are based. In this process, the fixed flat sample is subjected to stress by an abrasive fabric under defined parameters (pressure, movement, frequency, medium) for a defined period.  <\/p>\n<ul>\n<li><strong><strong>Industries: <\/strong><\/strong>Automotive Suppliers, Textile<\/li>\n<li><strong><strong>Analysis Objectives: <\/strong><\/strong>Initial Sample Release Inspection, Verification against Abrasion and Wear<\/li>\n<li><strong>Materials: <\/strong>Fabrics, Plastic Finished Parts, Painted Components<\/li>\n<li><strong>Analytical Methods: <\/strong>Martindale<\/li>\n<li><strong>Complementary Methods: <\/strong>Color Measurement, Grey Scale ABREX, Crockmeter, Taber<\/li>\n<\/ul>\n<h5>Results<\/h5>\n<p class=\"p1\">After the stress test, the evaluation is performed according to the specified standards. As a rule, the grey scale according to DIN EN 20105-A02 and DIN EN 20105-A03 is also evaluated. <\/p>\n<h5 class=\"p1\"><b>Advantages<\/b><b><\/b><\/h5>\n<p class=\"p1\">Abrasion and wear testing devices make it possible to investigate wear on technical textiles in the laboratory. Additionally, by simultaneously exposing them to various media, their influence on abrasion and wear behavior can be simulated in an accelerated manner. Based on the results of these tests, the suitability and quality of materials can be assessed.  <\/p>\n<\/div><\/div><div class=\"elementor-widget-cmsmasters-toggles__item\"><h3 id=\"elementor-tab-title-7248\" class=\"elementor-widget-cmsmasters-toggles__title\" data-tab=\"8\" aria-expanded=\"false\" aria-controls=\"elementor-widget-cmsmasters-toggles__content-7248\" tabindex=\"0\"><a class=\"elementor-widget-cmsmasters-toggles__title-link cmsmasters_enable_trigger_icon\" href=\"#\" tabindex=\"-1\"><span class=\"elementor-widget-cmsmasters-toggles__item-icon\"><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-far-file-pdf\" viewbox=\"0 0 384 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M369.9 97.9L286 14C277 5 264.8-.1 252.1-.1H48C21.5 0 0 21.5 0 48v416c0 26.5 21.5 48 48 48h288c26.5 0 48-21.5 48-48V131.9c0-12.7-5.1-25-14.1-34zM332.1 128H256V51.9l76.1 76.1zM48 464V48h160v104c0 13.3 10.7 24 24 24h104v288H48zm250.2-143.7c-12.2-12-47-8.7-64.4-6.5-17.2-10.5-28.7-25-36.8-46.3 3.9-16.1 10.1-40.6 5.4-56-4.2-26.2-37.8-23.6-42.6-5.9-4.4 16.1-.4 38.5 7 67.1-10 23.9-24.9 56-35.4 74.4-20 10.3-47 26.2-51 46.2-3.3 15.8 26 55.2 76.1-31.2 22.4-7.4 46.8-16.5 68.4-20.1 18.9 10.2 41 17 55.8 17 25.5 0 28-28.2 17.5-38.7zm-198.1 77.8c5.1-13.7 24.5-29.5 30.4-35-19 30.3-30.4 35.7-30.4 35zm81.6-190.6c7.4 0 6.7 32.1 1.8 40.8-4.4-13.9-4.3-40.8-1.8-40.8zm-24.4 136.6c9.7-16.9 18-37 24.7-54.7 8.3 15.1 18.9 27.2 30.1 35.5-20.8 4.3-38.9 13.1-54.8 19.2zm131.6-5s-5 6-37.3-7.8c35.1-2.6 40.9 5.4 37.3 7.8z\"><\/path><\/svg><\/span><span class=\"elementor-widget-cmsmasters-toggles__title-text\">Silicone Coating of Fabrics<\/span><\/a><span class=\"elementor-widget-cmsmasters-toggles__trigger\"><span class=\"elementor-widget-cmsmasters-toggles__trigger-closed\"><i aria-hidden=\"true\" aria-label=\"Closed\" class=\"cmsmsdemo-icon- cmsms-demo-icon-plus\"><\/i><\/span><span class=\"elementor-widget-cmsmasters-toggles__trigger-opened\"><i aria-hidden=\"true\" aria-label=\"Opened\" class=\"cmsmsdemo-icon- cmsms-demo-icon-minus\"><\/i><\/span><\/span><\/h3><div id=\"elementor-widget-cmsmasters-toggles__content-7248\" class=\"elementor-widget-cmsmasters-toggles__content elementor-clearfix\" data-tab=\"8\"><h4 class=\"p1\">Silicone Coating of Fabrics \u2013 Analysis &amp; Durability Testing<\/h4>\n<h5>Problem Statement<\/h5>\n<p class=\"p1\">Fabrics are often coated with silicone for protection or to increase gas tightness.

In this <\/p>\n<ul>\n<li><strong>Industries: <\/strong>Fabric Manufacturers, Fiber Manufacturers<\/li>\n<li><strong><strong><strong>Analysis Objectives: <\/strong><\/strong><\/strong>Coating Thickness, Penetration Depth<\/li>\n<li><strong>Materials: <\/strong>Coated Fabrics<\/li>\n<li><strong>Analytical Methods: <\/strong>Scanning Electron Microscopy (SEM\/EDX)<\/li>\n<\/ul>\n<section>\n<p>Fig. 1 (left) shows the coated front side of the fabric. The coating thickness on the fabric crests is so thin that the darker-appearing fibers are clearly visible through the coating. Thus, it offers only rather limited protection for the crests. On the other hand, the silicone has accumulated in the depressions of the fabric, forming the bright area. On the reverse side of the fabric (Fig. 1, right), a small amount of coating material (brightly illuminated) that has penetrated through the fabric can be observed at the intersection points between warp and weft threads.     <\/p>\n<p>In cross-section (Fig. 2), the coating thickness can be precisely measured at every point. As expected from the surface images (Fig. 1), the coating is completely absent from the fabric crests. Furthermore, illustrative information is obtained about the penetration depth of the coating into the fiber bundle (here 1\u20132 filament layers) and thus about the quality of wetting and the resulting adhesion properties.   <\/p>\n<p>Possible defects within the coating or between the fiber and the coating can also be investigated in this manner. Additionally, the local elemental composition of the coating can be determined via X-ray microanalysis (SEM-EDX), making inhomogeneities (e.g., particle inclusions) detectable. <\/p>\n<h5>Advantages<\/h5>\n<p>The described method allows for precise visualization and analysis of the layer structure, possible defects, and the measurement of local layer thickness. Furthermore, the adhesion mechanism can be further investigated by examining the penetration depth of the coating into the fiber bundle. The method is also suitable for other types of coatings (e.g., PVC) or for the analysis of laminates.  <\/p>\n<\/section>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-35566 size-full\" src=\"https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb-1-Vorder-links-und-Rueckseite-rechts-eines-einseitig-mit-Silikonbeschichteten-Airbag-Gewebes.jpeg\" alt=\"\" width=\"731\" height=\"299\" srcset=\"https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb-1-Vorder-links-und-Rueckseite-rechts-eines-einseitig-mit-Silikonbeschichteten-Airbag-Gewebes.jpeg 731w, https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb-1-Vorder-links-und-Rueckseite-rechts-eines-einseitig-mit-Silikonbeschichteten-Airbag-Gewebes-300x123.jpeg 300w, https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb-1-Vorder-links-und-Rueckseite-rechts-eines-einseitig-mit-Silikonbeschichteten-Airbag-Gewebes-30x12.jpeg 30w, https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb-1-Vorder-links-und-Rueckseite-rechts-eines-einseitig-mit-Silikonbeschichteten-Airbag-Gewebes-24x10.jpeg 24w\" sizes=\"auto, (max-width: 731px) 100vw, 731px\"><\/p>\n<p class=\"p1\"><strong>Fig. 1: Front (left) and reverse (right) sides of a single-sided silicone-coated airbag fabric.<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-35567 size-full\" src=\"https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb.-2-Querschnitt-durch-ein-einseitig-mit-Silikon-beschichtetes-Gewebe.jpeg\" alt=\"\" width=\"464\" height=\"335\" srcset=\"https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb.-2-Querschnitt-durch-ein-einseitig-mit-Silikon-beschichtetes-Gewebe.jpeg 464w, https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb.-2-Querschnitt-durch-ein-einseitig-mit-Silikon-beschichtetes-Gewebe-300x217.jpeg 300w, https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb.-2-Querschnitt-durch-ein-einseitig-mit-Silikon-beschichtetes-Gewebe-416x300.jpeg 416w, https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb.-2-Querschnitt-durch-ein-einseitig-mit-Silikon-beschichtetes-Gewebe-30x22.jpeg 30w, https:\/\/aso-labor.de\/wp-content\/uploads\/2025\/04\/Abb.-2-Querschnitt-durch-ein-einseitig-mit-Silikon-beschichtetes-Gewebe-14x10.jpeg 14w\" sizes=\"auto, (max-width: 464px) 100vw, 464px\"><\/p>\n<p class=\"p1\"><strong>Fig. 2: Cross-section of a single-sided silicone-coated fabric <\/strong><\/p>\n<\/div><\/div><div class=\"elementor-widget-cmsmasters-toggles__item\"><h3 id=\"elementor-tab-title-7249\" class=\"elementor-widget-cmsmasters-toggles__title\" data-tab=\"9\" aria-expanded=\"false\" aria-controls=\"elementor-widget-cmsmasters-toggles__content-7249\" tabindex=\"0\"><a class=\"elementor-widget-cmsmasters-toggles__title-link cmsmasters_enable_trigger_icon\" href=\"#\" tabindex=\"-1\"><span class=\"elementor-widget-cmsmasters-toggles__item-icon\"><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-far-file-pdf\" viewbox=\"0 0 384 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M369.9 97.9L286 14C277 5 264.8-.1 252.1-.1H48C21.5 0 0 21.5 0 48v416c0 26.5 21.5 48 48 48h288c26.5 0 48-21.5 48-48V131.9c0-12.7-5.1-25-14.1-34zM332.1 128H256V51.9l76.1 76.1zM48 464V48h160v104c0 13.3 10.7 24 24 24h104v288H48zm250.2-143.7c-12.2-12-47-8.7-64.4-6.5-17.2-10.5-28.7-25-36.8-46.3 3.9-16.1 10.1-40.6 5.4-56-4.2-26.2-37.8-23.6-42.6-5.9-4.4 16.1-.4 38.5 7 67.1-10 23.9-24.9 56-35.4 74.4-20 10.3-47 26.2-51 46.2-3.3 15.8 26 55.2 76.1-31.2 22.4-7.4 46.8-16.5 68.4-20.1 18.9 10.2 41 17 55.8 17 25.5 0 28-28.2 17.5-38.7zm-198.1 77.8c5.1-13.7 24.5-29.5 30.4-35-19 30.3-30.4 35.7-30.4 35zm81.6-190.6c7.4 0 6.7 32.1 1.8 40.8-4.4-13.9-4.3-40.8-1.8-40.8zm-24.4 136.6c9.7-16.9 18-37 24.7-54.7 8.3 15.1 18.9 27.2 30.1 35.5-20.8 4.3-38.9 13.1-54.8 19.2zm131.6-5s-5 6-37.3-7.8c35.1-2.6 40.9 5.4 37.3 7.8z\"><\/path><\/svg><\/span><span class=\"elementor-widget-cmsmasters-toggles__title-text\">Cleaning Cloth with Stains<\/span><\/a><span class=\"elementor-widget-cmsmasters-toggles__trigger\"><span class=\"elementor-widget-cmsmasters-toggles__trigger-closed\"><i aria-hidden=\"true\" aria-label=\"Closed\" class=\"cmsmsdemo-icon- cmsms-demo-icon-plus\"><\/i><\/span><span class=\"elementor-widget-cmsmasters-toggles__trigger-opened\"><i aria-hidden=\"true\" aria-label=\"Opened\" class=\"cmsmsdemo-icon- cmsms-demo-icon-minus\"><\/i><\/span><\/span><\/h3><div id=\"elementor-widget-cmsmasters-toggles__content-7249\" class=\"elementor-widget-cmsmasters-toggles__content elementor-clearfix\" data-tab=\"9\"><h4 class=\"p1\">Cleaning Performance Test<\/h4>\n<h5>Problem Statement<\/h5>\n<p class=\"p1\">Special cloths, already impregnated with a cleaning and care product, are often used for surface cleaning. Sealed in foil, these are only removed shortly before use. In one instance, individual cleaning cloths showed distinct dark spots immediately after opening the packaging. It was suspected that these could be grease stains.   <\/p>\n<h5>Solution<\/h5>\n<p class=\"p1\">Analytik Service Obernburg utilizes microscopic techniques for the analysis of such stains. The filamentous structure of the very dark contamination clearly indicates a fungal infestation. Consultation with the client revealed that the cleaning medium had recently been changed to a new product, and the new medium no longer contained alcohol. To prevent this, a cleaning solution with fungicidal agents or subsequent sterilization was recommended.   <\/p>\n<ul>\n<li><strong>Industries: <\/strong>Automotive Suppliers, Chemistry, Electronics, Paints and Coatings, Plastics Processors, Mechanical Engineering, Medical Technology<\/li>\n<li><strong><strong><strong>Analysis Objectives: <\/strong><\/strong><\/strong>Failure Analysis<\/li>\n<li><strong>Materials: <\/strong>Contaminants of all types<\/li>\n<li><strong>Analytical Methods: <\/strong>Light Microscopy, Scanning Electron Microscope<\/li>\n<li><strong>Complementary Methods:<\/strong> IR Spectroscopy<\/li>\n<li><strong>Related Issues:<\/strong> Inclusions<\/li>\n<\/ul>\n<section>\n<p class=\"p1\">Additionally, individual particles were observed between the large dark spots, which also needed to be characterized. For this purpose, this area of the cloth was analyzed using a scanning electron microscope. This method allows for the elemental analysis of the smallest areas (Fig. 3), in addition to displaying topography and material differences (Fig. 2).  <\/p>\n<p class=\"p1\">Based on their composition, the particles are attributable to mineral contaminants and likely represent subsequent contamination due to handling, which occurred when the cloth was removed from its packaging.<\/p>\n<h5>Advantages<\/h5>\n<p class=\"p1\">The combination of light and electron microscopy is an effective method for stain investigation, provided the images obtained are expertly interpreted. Furthermore, Analytik Service Obernburg possesses extensive expertise in other microscopic and spectroscopic methods. <\/p>\n<\/section>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone

If such problems occur, identifying the root cause is essential. <\/p>\n<h5>Solution<\/h5>\n<p class=\"p1\">In such cases, Analytical Services Obernburg frequently employs scanning electron microscopy (SEM). This provides images with high resolution and depth of field. In conjunction with X-ray microanalysis (EDX), it also allows for the characterization of the elemental composition of the smallest defect areas.  <\/p>\n<ul>\n<li><strong><strong>Industries: <\/strong><\/strong>Fiber Manufacturers, Weaving Mills, Coaters<\/li>\n<li><strong><strong><strong>Analysis Objectives: <\/strong><\/strong><\/strong>Failure Analysis<\/li>\n<li><strong>Materials: <\/strong>Fabrics<\/li>\n<li><strong>Analytical Methods: <\/strong>Scanning Electron Microscopy (SEM-EDX), Light Microscopy<\/li>\n<\/ul>\n<section>\n<h5>Advantages<\/h5>\n<p class=\"p1\">With the aid of scanning electron microscopy, defects in textile fabrics can be investigated in various ways. This allows for quick acquisition of information about their topography and elemental composition. The results obtained often allow conclusions to be drawn about the root cause of the defect, from which solutions for future defect prevention can be derived.  <\/p>\n<h5 class=\"p1\">Example \u2013 Fabric with Dark Stripe<\/h5>\n<p class=\"p1\">The dark stripe in the fabric was caused by inorganic contamination in the form of tiny particles (brightly illuminated in the material contrast image). This contamination affects only one thread; the weft threads are not affected. Therefore, it can be assumed that the contamination was applied to the thread before the weaving process. Precise elemental analysis of the contamination (EDX) provides information about the composition of the particles. Accordingly, rust particles (Fe\/O) are responsible for the discoloration.    <\/p>\n<h5 class=\"p1\">Example \u2013 Irregular Surface on Coated Fabric<\/h5>\n<p class=\"p1\">A PVC-coated fabric sample exhibits pock-like elevations on its surface.

For this purpose, a temperature chamber is used, which can be cooled down to temperatures as low as -80 \\u00b0C by means of liquid nitrogen cooling. On the other hand, high temperatures up to 200 \\u00b0C can also be reached by means of a forced air heater. This temperature chamber is operated in combination with a universal tensile testing machine (maximum tensile force 10 kN) and special clamping tools.

If this emulsion is measured with activated ultrasound, the droplets can be reduced in size, forming a stable distribution with a maximum at 2 \\u00b5m (yellow curve). The good (stable) emulsion shows the same distribution with and without ultrasound (green curve).

Furthermore, the material contrast image allows for the study of PVC penetration into the fiber bundle, providing insights into the existing adhesion mechanisms.    <\\\/p>\\n<\\\/section>\\n<p><img class=\\\"alignnone wp-image-35575 size-full\\\" src=\\\"https:\\\/\\\/aso-labor.de\\\/wp-content\\\/uploads\\\/2025\\\/04\\\/Abb.-1-Beispiel-Gewebe-mit-dunklem-Streifen.jpeg\\\" alt=\\\"\\\" width=\\\"711\\\" height=\\\"510\\\"><\\\/p>\\n<p class=\\\"p1\\\"><strong>Fig. 1 Example \\u2013 Fabric with Dark Stripe <\\\/strong><\\\/p>\\n<p><img class=\\\"alignnone wp-image-35574 size-full\\\" src=\\\"https:\\\/\\\/aso-labor.de\\\/wp-content\\\/uploads\\\/2025\\\/04\\\/Rasterelektronenmikroskopische-Aufnahmen-des-Topografiekontrasts.jpeg\\\" alt=\\\"\\\" width=\\\"903\\\" height=\\\"323\\\"><\\\/p>\\n<p class=\\\"p1\\\"><strong>Fig. 2: Scanning electron micrographs of the topography contrast (left) and material contrast (right) of a PVC-coated fabric in cross-section. <\\\/strong><\\\/p>\\n\"}},{\"@type\":\"Question\",\"name\":\"Determination of Spin Finish\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"<h4 class=\\\"p1\\\">Analyses on Yarns &amp; Textiles<\\\/h4>\\n<h5>Introduction<\\\/h5>\\n<p><span style=\\\"font-weight: 400;\\\">Spin finish, also known as spin oil or spinning auxiliary, is an essential component in the production of yarns and subsequently fabrics for technical or textile applications. These are liquid or pasty formulations applied to the surface of fibers to improve their physical properties and thus facilitate the processing step. The determination of spin finish is therefore crucial for the quality and efficiency of the product and subsequent processing steps.  <\\\/span><\\\/p>\\n<h5>Methods<\\\/h5>\\n<p><span style=\\\"font-weight: 400;\\\">There are various methods for determining spin finish, which can be used depending on requirements and available resources:<\\\/span><\\\/p>\\n<ol>\\n<li style=\\\"font-weight: 400;\\\" aria-level=\\\"1\\\"><b>Wet Chemical Extraction Method<\\\/b><span style=\\\"font-weight: 400;\\\">: This traditional gravimetric method involves the extraction of the spin finish from the fibers with a suitable solvent and the subsequent gravimetric determination of the extract. Although this method is precise, it requires the use of chemicals. <\\\/span><\\\/li>\\n<\\\/ol>\\n<h5><b>Time Domain Nuclear Magnetic Resonance (TD-NMR)<\\\/b><span style=\\\"font-weight: 400;\\\">: <\\\/span> <\\\/h5>\\n<p><span style=\\\"font-weight: 400;\\\">This modern method utilizes nuclear magnetic resonance to determine the spin finish content. The advantage of this method lies in its high accuracy and repeatability, as well as rapid results delivery. The gravimetric method serves as the basis for this quantification. Once established, however, it provides an unbeatably fast and solvent-free method.   <\\\/span><\\\/p>\\n\"}}]}<\/script> <\/div>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-06a1d4f e-flex e-con-boxed cmsmasters-block-default e-con e-parent\" data-id=\"06a1d4f\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-9dbbd2d cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-heading\" data-id=\"9dbbd2d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">H\u00e4ufig gestellte Fragen<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div data-separate-animation-selector=\".elementor-widget-cmsmasters-toggles__item\" data-text-animation-class=\"sequental, random\" class=\"elementor-element elementor-element-03a15a0 elementor-widget__width-initial elementor-widget-tablet__width-inherit cmsmasters-item-icon-position-right cmsmasters-title-alignment-left cmsmasters-trigger-icon-view-default cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-cmsmasters-toggles cmsmasters-widget-toggles\" data-id=\"03a15a0\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings='{\"toggles\":[{\"toggle_title\":\"Welche Textilpr\\u00fcfungen bieten Sie an?\",\"toggle_content\":\"&lt;p&gt;Faseridentifikation, Zugfestigkeit, Abriebpr\\u00fcfung, Lichtechtheit, Waschbest\\u00e4ndigkeit und chemische Analyse von Fasern und Geweben.&lt;\\\/p&gt;\\n\",\"_id\":\"338469c\",\"content_type\":\"toggle-content\",\"saved_section\":null,\"saved_template\":null,\"item_icon\":{\"value\":\"\",\"library\":\"\"},\"toggle_custom_id\":\"\"},{\"toggle_title\":\"K\\u00f6nnen Sie Fasertypen identifizieren?\",\"toggle_content\":\"&lt;p&gt;Ja.
