ActiveTextiles—Quantitative chemical analysis—Mixtures of meta-aramid and para-aramid fibres（method using dimethylacetamide and lithium chloride）
纺织品 定量化学分析 间位芳香族聚酰胺纤维与对位芳香族聚酰胺纤维的混合物（氯化锂/N,N-二甲基乙酰胺法）
Application Summary AI generated
This standard specifies a quantitative chemical analysis method using a solvent mixture of dimethylacetamide and lithium chloride to determine the composition of blends containing meta-aramid and para-aramid fibers. It is applied in textile testing laboratories and quality control settings for products such as protective clothing, industrial fabrics, and high-performance textiles where precise fiber content verification is required. The method ensures accurate separation and measurement of these two aramid fiber types, which have similar chemical resistance but different thermal and mechanical properties.
