壳聚糖纤维与棉混纺纱前处理及染色工艺研究

Study of Pretreatment and Dyeing Process of Chitosan and Cotton Blended Yarn

壳聚糖纤维具有良好的保湿性、抑菌性、可降解性等,在纺织品领域具有较好的应用价值。文中对壳聚糖纤维与棉混纺纱进行前处理,并分别采用活性染料、直接染料进行染色加工,测试了前处理及染色前后纱线壳聚糖含量的变化,染色后耐水洗色牢度及耐汗渍色牢度。结果表明,煮练后壳聚糖纤维含量基本保持不变,染色后壳聚糖含量仍达到要求,且纱线耐水洗及耐汗渍色牢度较好。

Chitosan fiber has good moisture retention, antibacterial property and degradability,which has good application value in the field of textiles. This paper pretreated chitosan and cotton blended yarn by using reactive dyes and direct dyes for dyeing process. The changes of the content of the chitosan before and after dyeing, color fastness to washing and perspiration fastness were tested. The results show that the content of chitosan fiber basical-ly remain unchanged after scouring, the content of chitosan can meet the requirements after dyeing, and the fast-ness to washing and perspiration is good.
