China Updates Standard for Man-made Fiber Generic Names
A look at China’s updated standard for the generic names of man-made fibers – GB/T 4146.1-2020.
- (1888PressRelease) March 06, 2021 - China has updated its national standard covering the generic names for man-made fibers – GB/T 4146.1-2020 Textiles-Man-made fibers – Part 1: Generic names.
Issued as part of China’s No. 22 announcement on newly approved national standards in 2020, the new standard will come into effect on May 1, 2021. It covers all man-made fibers, defined as those obtained by a manufacturing process and not being natural.
The new standard includes several revisions to the previous iteration – GB/T 4146.1-2009.
Additions include:
• Term and definitions for man-made fibers
• Generic names, codes, distinguishing attributes and chemical formulae for 11 kinds of man-made fiber, including modacrylic, chitosan, melamine, protein, trivinyl, polybenzimiazol, elastomultiester, polyamidoester, silicon carbide, polyhydroxy, polyarylate
• Bicomponent fiber names
Revisions to the standard include:
• Division of vinylal into two categories:
1. Acetalization
2. Non-acetalization
• Table 2 and Table 3 (2009 edition) become Appendix D and Appendix E
The use of a generic name is limited to those fibers that contain no more than 15% (by mass) of property-enhancing additives prior to spinning (no limit is placed upon the proportion of additives that are not property-enhanced). A generic name may also apply to a man-made fiber which results from a manufacturing process that can confer a distinguishing attribute.
