Zhang Xiaoli, Wu Yingzhu, Liang Guan, Huang Haimin, Huang Meilin, Li Konglan, Xie Xiaobo. Quantitative analysis method for import and export textile polyester fiber

1 Scope

This standard specifies the use of a microprojector method in a molten state to contain polyparaphenylene in a blend of non-polyester fibers that have been removed. Two or three of ethylene glycol diester (PET), polytrimethylene terephthalate (PTT) and polybutylene terephthalate (PBT) A quantitative analysis method. This standard applies to the quantitative analysis of textiles and their products containing polyester fibers.

2 Normative references

The terms in the following documents become the terms of this standard by reference to this standard. For dated references, only dated The version applies to this document.
