GB/T 7568.7-2008 Multi-fiber standard lining fabric for focusing Spinning & weaving product colour fastness test. This standard specifies the composition of multi-fiber lining fabric in detail, covering the types and proportions of fibers contained. It specifies its physical performance indicators, such as fabric density, thickness, etc., and Appearance mass standards. The specification of such lining fabrics aims to provide a unified and stable reference for Spinning & weaving product colour fastness test, ensure that the test results of different laboratories and batches are comparable, help the Spinning & weaving industry to accurately evaluate colour fastness, and promote the standardization of mass testing work.
