Silk is a continuous long fiber formed by the solidification of silk liquid secreted by mature silkworms during cocooning, also known as natural silk, which is a type of natural fiber. One of the earliest animal fibers utilized by humans. Silk is the lightest, softest, and thinnest natural fiber in nature. It can be easily restored to its original state after removing external forces. The inner tube does not cake, stuffy, or shrink, is uniform and soft, and can be permanently used without flipping The detection range includes silk: mulberry silk, tussah silk, cassava silk, camphor silk, willow silk, heavenly silk, etc; Fabric: natural silk fabric facial mask, quilt, clothes, pillow cases, facial mask, bags, scarves, etc; Fabric: Silk fabrics such as Luo, Ling, Wan, Yarn, Crepe, Qi, Jin, Embroidery, etc The testing items include compression resilience, shrinkage rate of tire cover, color fastness of tire cover, washing resistance, sweat resistance, friction resistance, appearance quality, filling material quality, composition, formaldehyde, pH value, azo, odor, filling material oil, moisture, ash, protein, ether soluble extract, fiber, silk fibroin, sericin, oils, pigments, inorganic substances, etc The detection standard is (partially) DIN EN ISO 156 0190 2607-18-2011: Quantitative chemical analysis of textiles Part 18: Mixtures of silk and wool or other animal hair fibers (sulfuric acid method) FZ/T 01112-2012: Quantitative chemical analysis of textiles Mixtures of silk and wool or/and cashmere (formic acid/zinc chloride method) FZ/T 01132-2016: Quantitative Chemical Analysis of Textiles - Mixtures of Vinylon Fibers and Certain Other Fibers FZ/T 01134-2016: Quantitative Chemical Analysis of Textiles - Mixtures of Polysulfone Fibers and Certain Other Fibers FZ/T 01135-2016: Quantitative Chemical Analysis of Textiles - Mixtures of Polypropylene Fibers and Certain Other Fibers FZ/T 01136-2016: Quantitative Chemical Analysis of Textiles - Mixtures of Carbon Fibers and Certain Other Fibers
