Fabric quality standards cover raw material and yarn specifications. High-quality fabrics require pure fibers, uniform length, low breakage rate, moderate yarn twist, and adequate strength. For natural fibers such as cotton, linen, silk, and wool, the impurity content, fiber length, and fineness are important criteria for evaluating fabric quality; for chemical fiber fabrics, the focus is on fiber uniformity, strength, and abrasion resistance. High-quality raw materials are the foundation of fabric comfort, durability, and appearance.
Fabric quality standards cover weaving or knitting process specifications. Fabrics should have uniform density, tightly packed and even warp and weft yarns, and be free of defects, broken yarns, or weft slippage. Uniform thickness, good drape, and moderate elasticity are key factors in determining fabric grade and suitability. Knitted fabrics also require attention to uniform stitch spacing, elastic recovery rate, and loop integrity to ensure the comfort and dimensional stability of finished garments.
Fabric quality standards also include finishing and functional requirements. Colorfastness, printing uniformity, softness, wrinkle resistance, and water or UV protection are all important assessment indicators. Standardized testing can be conducted through national textile industry standards, international ISO standards, or internal company specifications, including color fastness testing, tensile strength testing, and shrinkage testing. Comprehensive quality standards ensure that fabrics meet the diverse application requirements in terms of comfort, aesthetics, and functionality.
