T/CCTA 40501-2023 Polyester-cotton blended colored imitation wool elastic fabric
T/CCTA 40501-2023
Basic Information
Scope
Main technical content: It specifies the terms and definitions, specifications and classification, requirements, test methods, inspection rules and marks, packaging, transportation and storage of dyed and woven wool-like elastic fabrics made of polyester and viscose blends. The requirements for dyed and woven wool-like elastic fabrics made of polyester and viscose blends are divided into two aspects: intrinsic quality and appearance quality. Intrinsic quality includes density deviation rate, breaking strength, tensile elongation at break, plastic deformation rate, tear strength, seam slippage, pilling, and water-washing dimension change rate, fiber content, and color fastness. Appearance quality includes width deviation, color difference, weft skew/warp skew, and fabric surface defects
