Foreword

The entire technical content of this document is mandatory.

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting.

This document replaces GA 365-2009 "Interwoven Silk". Compared with GA 365-2009, except for structural adjustment and editorial changes, the main technical the changes are as follows.

a) The raw material uses new special-shaped functional polyester fiber, which complies with the standard of China Chemical Fiber Industry Association. HX/T 51003.5-2013;

b) Added a chapter on classification (see Chapter 4);

c) Added polyester fiber cross-sectional shape, tear strength, appearance flatness after washing, bending length, drip diffusion time, wicking height, Evaporation rate, air permeability, whiteness value, hiding performance, light fastness, perspiration color fastness index (see 5.4, 5.5);

d) Delete the water diffusion time, water drying rate, and UV protection performance indicators (see 3.4 of the 2009 edition);

e) Changed the full width, density, fiber content, mass per unit area, breaking strength, total crease recovery angle, washing dimensional change rate, dry Thermal dimensional change rate, triboelectric charge surface density index (see 5.4, 3.4 of the 2009 edition);

f) Changed the indicator of color fastness to light (see 5.5, 3.5 of the 2009 edition);

g) Changed the security requirement indicators (see 5.6, 3.6 of the 2009 edition);

h) Changed appearance defects (see 5.7, 3.7 of the 2009 edition);

i) Changed Appendix A.
