China – Textile Standard GB/T 4146.1-2020 Approved to Replace 2009 Version
Vol. 1199 | 12 Nov 2020
The Standardization Administration of the People’s Republic of China recently released announcement No.22 of 2020, which included an update that GB/T 4146-2020 “Textiles—Man-made fibers—Part 1: Generic names” has replaced the 2009 version. It will be effective on May 1, 2021.
The new version includes many updates to the old version, with the key technical differences as follows:
- Added terms and definitions of “man-made fibre/ chemical fibre”.
Man-made fibre/ chemical fibre: Fibres which are made by man, except natural fibres. - Added generic name, symbol, main characteristic and chemical formula to 12 kinds of chemical fibres, including:
Modacrylic, chitosan, melamine, protein, trivinyl, polybenzimidazol, elastomultiester, polyamidoester, silicon carbide, polyhydroxy, polycarbamide and polyarylate. - Polyvinyl alcohol fibres are divided into acetal and non-acetal types, specified vinylon is short for polyvinyl alcohol fibre.
- Added the name of bicomponent composite fibre, such as:
聚酯/聚酯复合纤维：Polyester/polyester bicomponent
聚乙烯/聚丙烯复合纤维：Polyethylene/polypropylene bicomponent
聚丙烯/聚酰胺复合纤维：Polypropylene/polyamide bicomponent
聚酯/聚酰胺复合纤维：Polyester/polyamide bicomponent
聚乙烯/聚对苯二甲酸乙二醇酯复合纤维：Polyethylene/polyester bicomponent - Added 4 informative annexes, including:
- Annex A: Suggested rules for establishing generic names
- Annex B: Composite fibre
- Annex C: Modified fibre
- Annex F: Requirements for generic names in related region and state
The generic names for chemical fibres in the new standard are shown in the following table:
