GB/T 2910.20-2009
ActiveTextiles - Quantitative chemical analysis - Part 20: Mixtures of elastane and some other fibers (method of using dimethylacetamide)
纺织品 定量化学分析 第20部分：聚氨酯弹性纤维与某些其他纤维的混合物（二甲基乙酰胺法）
Application Summary AI generated
This standard specifies a quantitative chemical analysis method using dimethylacetamide to determine the proportion of elastane (polyurethane elastic fiber) in mixtures with other fibers such as wool, cotton, or polyester. It is applied in textile quality control laboratories and manufacturing settings to verify fiber composition labels on stretch fabrics, including sportswear, hosiery, and elastic garments. The method ensures accurate material content assessment for compliance with trade regulations and product specifications.
