摘要
根据聚乳酸/棉混纺产品中两种纤维不同的溶解性能,选取75%硫酸、二氯甲烷、5%氢氧化钠和88%甲酸作为溶解试剂对聚乳酸和棉纤维进行定量分析,并对这四种分析方法的准确度和精密度进行了比较。结果表明,这四种分析方法的准确度和精密度均能满足GB/T 2910—1997国家标准要求。相比之下,采用二氯甲烷法准确度最高,75%硫酸法和5%氢氧化钠法精密度较高。
According to different dissolution performance of polylatic acid（PLA） fiber and cotton fiber, four quantitative analysis methods for PLA/cotton blends were developed, such as 75% sulfuric acid, dichloromethane, 5 % sodium hydroxide and 88 % formic acid. Various trials were carried out to compare accuracy and precision of these four methods. Results showed that： accuracy and precision of these four methods could meet the requirements of GB/T 2910--1997 hydroxide standard. In these four methods, dichloromethane method had the highest accuracy, while 75% sulfuric acid and 5% sodium had better precision.
