GB/T 7568.4-2002 specifies the specifications of polyester lining fabrics for colour fastness testing of Spinning & weaving products. The standard details the fiber composition, yarn thickness and structure of polyester lining fabrics, and the requirements for warp and weft density, thickness and Appearance mass of fabrics. Uniform and strict specification setting ensures that polyester lining fabrics can provide a stable and consistent reference during colour fastness testing, so that the test data of different testing institutions are comparable, providing a basis for accurately evaluating the colour fastness of Spinning & weaving products, and assisting the Spinning & weaving industry to carry out mass testing.
