GB/Z 32012-2015New textile materials - Datasheet of chemical properties (English PDF)

Foreword

This instructional document has been drafted in accordance with the rules given in GB/T 1.1-2009. This Guidance Document is proposed by China National Textile and Apparel Council. The guidance of technical documents by the National Textile Standardization Technical Committee (SAC/TC209) centralized. The drafting of the guidance of technical documents. Textile Industry Standardization Institute, Textile Industry Science and Technology Development Center, Yantai Taihe new material Material Co., Ltd., Changshu Jinquan Chemical Fiber Weaving Co., Ltd., China Chemical Fiber Industry Association. The main drafters of this technical document are Si Ying, Xu Lu, Han Yuru, Liu Feifei, Wang Gujian, Li Deli, Song Cuiyan and Xiang Pengwei.

At present, aramid, polyphenylene sulfide fibers, ultra-high molecular weight polyethylene fibers, new polyester fibers, chitosan fibers, polylactic acid fiber and other high Fibers and new textile fibers developed rapidly, but mostly in the industrialization process, the basic data of a serious shortage of some books, information mentioned Part of the scattered data there is a big difference, and did not indicate the test method, is not comparable, can not meet the product development and application design Department of the material itself based on the performance data needs. The data of this instructional technical document originated from the scientific research special item "Research on basic performance data of textile new material" Fruit, is collected on the basis of the measured value of the sample is given, there are some limitations. Unlike the existing product standards, this guidance document is not a specification of the performance of the final product and is not intended as a Determine whether the product is qualified basis. This guideline is for reference only. The suggestions and opinions on this technical document are directed to the standardization administration under the State Council Department reflected. Textile New Material Chemical Property Data Sheet

1 Scope

This guiding technical document gives the basic chemical property data of certain textile fibres: chemical solubility and the retention of breaking strength after acid and alkali treatment. This guiding technical document applies to ultra-high molecular weight polyethylene fibre, aramid 1414, aramid 1313, polyphenylene sulfide fibre, polyimide fibre, polytrimethylene terephthalate fibre, polybutylene terephthalate fibre, polylactic acid fibre, chitosan fibre and lyocell fibre.

This guidance document gives the chemical basis of certain textile fibers for their chemical resistance, acid resistance, and alkali retention at fracture toughness The basic data. This guideline is applicable to UHMWPE fibers, aramid 1414, aramid 1313, polyphenylene sulfide fibers, polyimides Fibers, polytrimethylene terephthalate fibers, polybutylene terephthalate fibers, polylactic acid fibers, chitosan fibers and Lyocell fibers.
