GB/T 35249—2017 Standard Overview

GB/T 35249—2017 "Quantitative Chemical Analysis of Textiles - Mixtures of Polyphenylene Sulfide Fibers and Certain Other Fibers" is an important specification for quantitative chemical analysis of mixtures of polyphenylene sulfide fibers and other fibers. This standard is under the jurisdiction of the National Technical Committee for Standardization of Textiles and is applicable to two-component mixtures of polyphenylene sulfide fibers, including protein fibers, cellulose fibers, acetate fibers, and other fibers.

Background of Standard Formulation

With the development of the textile industry, the application of blended materials is becoming more and more extensive. As a high-performance synthetic fiber, polyphenylene sulfide fiber has important application value in industry and special fields. However, there is a lack of unified standards for the quantitative analysis of its mixtures with other fibers, resulting in inconsistent test results. To this end, this standard came into being, aiming to provide a scientific and unified method for the determination of the content of polyphenylene sulfide fibers in textiles.

Technical Points Analysis

The core of this standard is to remove non-fiber substances through chemical analysis methods and accurately determine the mass fraction of polyphenylene sulfide fiber and other fibers. According to the solubility characteristics of different types of fibers, the standard stipulates a variety of reagents and test steps to ensure the accuracy of the test results.
