GB/T 39621-2020
ActiveTextiles—Quantitative chemical analysis—Mixture of cross-linked lyocell fibres and viscose or cupro or modal (method using formic acid and zinc chloride)
纺织品 定量化学分析 交联型莱赛尔纤维与粘胶纤维、铜氨纤维、莫代尔纤维的混合物（甲酸/氯化锌法）
Application Summary AI generated
This standard specifies a quantitative chemical analysis method using formic acid and zinc chloride to determine the mass percentage of cross-linked lyocell fibers in mixtures with viscose, cupro, or modal fibers. It is applied in textile testing laboratories and quality control settings for the accurate identification and composition analysis of blended fabrics, particularly for products containing high-performance lyocell fibers. The method ensures compliance with labeling requirements and material specifications in the textile industry.
