摘　　要：聚乳酸纤维/羊毛混纺产品在进行定量化学分析时,可用二氯甲烷溶解聚乳酸纤维,剩余羊毛,也可用次氯酸钠溶液溶解羊毛,剩余聚乳酸纤维,这两种方法均具有可行性,但其结果存在一定的差异。通过对比试验结果显示：采用二氯甲烷溶解法试验,羊毛的修正系数为1.00,采用次氯酸钠溶解法试验,聚乳酸纤维的修正系数为1.03时,试验定量计算结果均较为准确,且两种方法的试验结果一致性较好。For chemical analysis of polylactide/wool blended products, one method is dissolving polylactide with dichloromethanc, and the other is dissolving wool with sodium hypochlorite solution. The two kinds of quantitative test methods are both feasible. However, there arc some differences in the quantitative results. Through comparative tests, the results show that the correction coefficient for wool is 1.00 in dichloromethane dissolution method, while the correction coefficient of polylactide is 1.03 in sodium hypochlorite dissolution method test. The test results are accurate after quantitative calculation, and test results of two methods have good consistency.
