&Textile Material Properties and Test Terms 2 is a revision of the national standard GR201:82 Textile Nomenclature (Textile Materials. Common Part of Textile Products>3 and GB57:85 Textile Performance and Test Terms for Grade 1 Textile Products) and compared with the original standard, some major changes have been made: - The vocabulary list has been revised, and the standard has been changed to textile material properties and test terms based on the properties of textile materials and textile products. 2. The standard is a set of terms related to the performance test of textile materials, excluding raw material terms, product terms, multi-point terminology and packaging terms. The original standard is difficult to change into a series of standards. The performance test terminology of textile materials is divided into three parts: Part 1: Fibers and yarns || TT || Part 2: Fabrics || TT || Part 3, and new terminology is added. Some terms and definitions in the original standard are retained and incorporated. This standard serves as a set of terms for the performance test of textile materials. Part 5 of the standard collects the general terminology of textile materials and test terms. From this month onwards, the terminology of textile materials for general use can be consulted (B32612 Textile terminology (Textile materials. Textile products. General part 3 and GB515735* Combustion performance of textile products and combined products - Vocabulary 3.G.291-82) is replaced by the English chapter 3 of the textile industry standard FZ01018-92 on textile machine terms. Appendix A and Appendix B of this standard are reminders: This standard The China National Textile and Apparel Council proposed: This standard is the responsibility of the National Textile Standardization Technical Committee Basic Standards Technical Committee, and the drafting unit of this standard is the Standardization Research Institute of the China National Textile and Apparel Council. The main drafters of the standard are Chen Narong and Zheng Ningying. 18
