Textile testing is the process of evaluating the quality and properties of a textile material through a series of tests at various stages of manufacturing. [1] Textile testing, like textiles, is a vast subject. The historical evolution of textile measuring, and testing methods is difficult to consolidate as the subject is scattered and has ...
Wet process engineering is the most significant division in textile preparation and processing. It is a major stream in textile engineering, which is under the section of textile chemical processing and applied science. Textile manufacturing covers everything from fiber to apparel; covering with yarn, fabric, fabric dyeing, printing, finishing ...
Iodine–starch test. A bottle of iodine solution used on apples to determine the correct harvest time. The chart shows the level of residual starch. The cut surface of an apple stained with iodine, indicating a starch level of 4–5. The iodine–starch test is a chemical reaction that is used to test for the presence of starch or for iodine.
The falling number method is uncomplicated, but requires an apparatus which follows the international standards. Such an apparatus consists of a water bath, a test tube, a stirring rod, and a stirring device. The test was performed manually when first employed, test instrumentation today is mostly automated. Flour samples can be analyzed directly.
The American Association of Textile Chemists and Colorists (AATCC) develop the test methods the textile industry use to ensure product quality. AATCC is the world's leading not-for-profit association serving textile professionals since 1921. AATCC, headquartered in Research Triangle Park, N.C., USA, provides test method development, quality ...
Desizing, irrespective of what the desizing agent is, involves impregnation of the fabric with the desizing agent, allowing the desizing agent to degrade or solubilise the size material, and finally to wash out the degradation products. The major desizing processes are: Enzymatic desizing of starches on cotton fabrics. Oxidative desizing.
Oeko-Tex is a registered trade mark of the International Association for Research and Testing in the Field of Textile and Leather Ecology. It is used to represent the product labels and company certificates issued by the Association. Oeko-Tex labels and certificates confirm the safety of textile products and leather articles from all stages of ...
Dimensional stability (fabric) Dimensional stability (in fabric) pertains to a fabric's ability to maintain its initial size and shape even after undergoing wear and care, which is a desirable property. [1] Textile manufacturing is based on the conversion of fiber into yarn, yarn into fabric, includes spinning, weaving, or knitting, etc.
