摘　　要：本文研究在常温条件下15 min内20%盐酸对纤维素纤维的质量修正系数值,并采用手工拆分法、手工拆分加拆后溶解法、20%盐酸按顺序溶解法三种方案分别对纤维素纤维/锦纶/氨纶混纺产品进行定量分析对比试验。结果表明:使用20%盐酸按顺序溶解法符合GB/T 29862—2013《纺织品纤维含量的标识》要求,可以大大节省时间,提高效率,相比于其他两种方法更适用于大批量混纺产品定量分析。This article studies the quality correction coefficient values of cellulose fibers treated with 20%hydrochloric acid within 15 minutes at room temperature.Three methods,namely manual splitting,manual splitting and dissolution after splitting,and sequential dissolution with 20%hydrochloric acid,were used to quantitatively analyze and compare cellulose fiber/nylon/spandex blended products.The results indicate that the sequential dissolution method using 20%hydrochloric acid meets the requirements of GB/T 29862—2013"Identification of Fiber Content in Textiles",which can greatly save time and improve efficiency.Compared with the other two methods,it is more suitable for quantitative analysis of large-scale blended products.
