壳聚糖在羊毛防毡缩整理中的应用

本文探讨了用壳聚糖对羊毛进行防缩整理的工艺。比较了单纯用壳聚糖处理和氧化后再用壳聚糖处理的效果,对不同氧化剂处理的效果进行了比较,找出了最佳的防缩工艺条件,并对绒线和毛衫进行了处理,测试了处理后的毡缩性和强度等指标。结果表明,壳聚糖可以作为羊毛防缩处理的树脂,但必须进行氧化预处理,才能达到满意的防缩效果。氧化处理采用次氯酸钠和高锰酸钾一起处理的效果,比单纯用次氯酸钠的效果要好,并可降低次氯酸钠的用量。此工艺简单,处理纱线和成衣毋需增加设备,成本较低,同时强度和手感等性能不受影响。

Wool Wrinkle Resistant Finish with Chitosan

Wool wrinkle resistant finish using chitosan as resin was researched. Two processes were introduced. One is chitosan finish,the other is chitosan finish after oxidation. The results of these two processes were compared. Different oxidants were introduced to the process. The optimum process condition was established. The knitting wool and woollen sweater were also finished with these processes. The felting behaviour and strength were tested. The results indicate that the chitosan can be used as resin to wool wrinkle resistant finish. The satisfied wrinkle resistance will be achieved combining oxidation first. Sodium hypochlorite (NaClO) together with potassium perman-ganate(KMnO4) as oxidants has excellent result than using NaClO itself and saving the NaClO. The advantages of this process is simple ,low cost and no influence on strength and hand.
