GB/T 35249-2017Textiles—Quantitative chemical analysis—Mixtures of polyphenylene sulfide fiber and some other fibers (English PDF)

1 Scope

This standard specifies the use of chemical analysis to determine the removal of non-fibrous material polyphenylene sulfide fibers and other fiber two-component mixture

In the fiber content of the method.

This standard applies to polyphenylene sulfide fibers and protein fibers (wool, silk, etc.), cellulose fibers (cotton, linen, viscose fibers, etc.)

Acetate, triacetate, polylactic acid, polyacrylonitrile, some modified polyacrylonitrile, spandex, polyamide, vinylon,

Polyester, aramid 1313, aramid 1414, polyimide, or polytetrafluoroethylene fibers.

3 principle

After the qualitative identification of the sample, select the appropriate reagent to dissolve one of the components, the residue was collected, washed, dried and weighed, and then repair

The mass after the calculation of mass fraction (%) of polyphenylene sulfide fibers and some other fibers.

Note. For identification test method see FZ/T 01057 and Appendix A.

4 test rules

Test reagents and equipment, sample preparation, test procedures, samples and insoluble fiber drying, cooling, weighing and analysis of the results are calculated

According to GB/T 2910.1 regulations. Such as test methods, test results calculated with the above provisions are different, according to the implementation of this standard.
