羊毛／莱赛尔混纺产品定量分析方法研究

摘要

In order to obtain more accurate results in fiber content percentage of material made from wool and lyocell blended produts, the solubility of wool and lyocell respectively dissolved in 75% sulfuric acid was studied. Under the best testing procedure defined, the test results showed that the deviation of fiber content percentage of wool and lyoeell fibers was not more than 1.0% using 75% sulfuric acid.%为了更好地对羊毛／莱赛尔二组分混纺产品中原料成分进行准确定量，研究了羊毛和莱赛尔分别在75％硫酸中的溶解情况，优选出最佳试验条件后，对羊毛和莱赛尔混纺产品进行试验。试验结果表明，75％硫酸对该类混纺产品进行准确定量是可行的，误差小于1.0％。
