Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard proposed by the China Textile Industry Federation. This standard by the National Textile Standardization Technical Committee (SAC/TC209) centralized. This standard was drafted. Textile Standard (Beijing) Inspection and Certification Center Co., Ltd., Shanghai Exit Inspection and Quarantine, Zhejiang Textile Standard Test Limited. Drafters of this standard. Zhang Huan Ran, Zhang Hui, Fei Jing, Shi Jing Jing. Textile Quantitative Chemical Analysis Teflon fibers and some other fiber mixture

1 Scope

This standard specifies the method for the determination of the content of two mixtures of Teflon fibers by chemical analysis. This standard applies to polytetrafluoroethylene fibers and some protein fibers (wool, silk, etc.), cellulose fibers (cotton, linen, viscose Etc.), two components of acetate, polyacrylonitrile, spandex, polyamide, polyester, polyimide and polyphenylene sulfide fibers mixture.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 2910.1 Textiles - Quantitative Chemical Analysis Part 1. General Principles of Testing GB/T 2910.4 Textiles Quantitative Chemical Analysis Part 4. Some protein fibers and some other fiber mixture (times Chlorate method) GB/T 2910.7 Textiles Quantitative Chemical Analysis Part 7. Polyamide fibers and some other fiber mixtures (formic acid method) GB/T 2910.11 Textiles - Quantitative chemical analysis - Part 11. Mixtures of cellulose fibers and polyester fibers (Sulfuric acid method)

3 principle

After qualitative identification of the sample, select the appropriate reagent to dissolve one of the components, the residue was collected, washed, dried and weighed, then amended After the mass calculated polytetrafluoroethylene fibers and some other fiber mass percentage. Note. The identification method can be FZ/T 01057 and Appendix A method.

4 test rules

Test analytical reagents, distilled water and equipment, sample preparation, test procedures, samples and insoluble fiber drying, cooling, weighing and analysis The results are calculated according to GB/T 2910.1 regulations. If the test method, the calculation of test results and the above provisions are different, then with Body test methods are listed. 5 Teflon fibers and some protein fiber mixture (hypochlorite method) 5.1 principle The hypochlorite solution is used to dissolve the protein fibers from the mixture of known dry mass, and the residue is collected, washed, dried and weighed Weight; calculated using the corrected mass of PTFE fibers as a percentage of the dry mass of the mixture. The difference results in the quality of the protein fiber percentage. 5.2 Reagents Use the reagents specified in GB/T 2910.4. ......
