摘要
标准GB/T 2910.10—2009规定采用二氯甲烷法对三醋酯纤维和聚酯纤维混纺及交织物进行定量化学分析,但是二氯甲烷作为一种有机溶剂,具有一定的毒性,被人体吸入会导致其中枢神经和呼吸系统受到损害,且二氯甲烷在地下水中有蓄积作用,对环境有一定的危害。针对这一问题,结合三醋酸纤维易溶于酸的特性,提出采用75%H2SO4溶解法进行测试,并与二氯甲烷法进行比较。结果表明,采用75%H2SO4法测定三醋酯纤维和聚酯纤维混纺织物或者交织物的纤维含量更加经济、方便和健康安全。可以考虑采用75%H2SO4法替代二氯甲烷法对三醋酯纤维和聚酯纤维混纺织物及交织物进行定量化学分析。
According to Standard GB/T2910.10--2009, dichloromethane is applied to quantitative chemical test of blended fabric and mixed fabric made from triacetate and polyester. However, dichloromethane is toxic as an organic solvent and will cause damage to the central nervous system and respiratory system if inhaled by human beings. It also has a negative impact on environment for its accumulation in groundwater. Owing to the characteristic of triacetate being easily soluble in acid, in this paper 75% H2SO4 is taken the place of dichloromethane to test the fiber content of blended fabric and mixed fabric made from triaeetate and polyester. From the testing results, it is found that the new method is more economical, more convenient and much safer. The new method is feasible and is recommended
