摘　　要：为了保证桑蚕丝与绵羊毛混纺产品纤维含量分析结果的准确性及测试效率,探讨了采用56%硫酸法测定此类产品纤维含量的可行性,并采用56%硫酸法和现行标准方法对不同含量的此类产品进行了比对试验。试验结果表明:绵羊毛在56%硫酸溶液中的修正值d为1.00;56%硫酸法与甲酸/氯化锌法、75%硫酸法以及35%盐酸法测试结果的含量差值均符合GB/T 29862—2013中规定的纤维含量允差要求。整个试验表明,采用56%硫酸法测定桑蚕丝/绵羊毛混纺比是可行的。In order to ensure the accuracy and efficiency of fiber content analysis on silk/wool blended products,comparative experiments were conducted to analyze the feasibility of using the 56%sulfuric acid method for the quantitative analysis of such blended textiles.The experimental results indicate that the mass correction factor d for wool in a 56%sulfuric acid solution is 1.00.The extreme differences in the content measured by the 56%sulfuric acid method compared to the 75%sulfuric acid method,35%hydrochloric acid method,and formic acid/zinc chloride method are all less than 3%,which complies with the fiber content tolerance described in GB/T 29862—2013.The experiment demonstrates that the use of the 56%sulfuric acid method for the quantitative an alysis of silk/wool blended products is feasible.
