丙三醇缩水甘油醚和壳聚糖对蚕丝织物的复合整理

 为了改善蚕丝织物的服用性能,提高其抗皱和抗菌性能,用丙三醇缩水甘油醚和壳聚糖对蚕丝织物进行后整理。采用微波辐照方法接枝丙三醇缩水甘油醚,再用壳聚糖醋酸溶液进行二浸二轧后整理。对整理后的蚕丝织物进行力学性能和白度测试。用正交分析法对整理工艺进行优化,得出最佳处理工艺。结果表明,经整理后,蚕丝织物的抗皱性有较大提高;织物的急弹性回复角提高50°左右,缓弹性回复角提高30°左右,断裂强力和白度略有下降。

Finishing of silk fabric with propanetriol-diglycidyl-ether and chitosan

The silk fabric was treated with propanetriol-diglycidyl-ether and chitosan in an attempt to improve its serviceability,anti-bacterial and wrinkle resistant properties.The grafting of propanetriol-diglycidyl-ether onto the silk fabric was accomplished by microwave radiation,followed by finishing the grafted fabric with the chitosan-acetic acid solution through double-dip-double-nip.The finishing process was optimized by means of orthogonal analytic method.The mechanical properties and the whiteness of the finished silk fabric were tested.The findings indicated that the treated silk fabric has improved its wrinkle resistance significantly with the angle of fast-elastic recovery enhanced about 50°,the angle of delayed-elastic recovery enhanced about 30°,and the breaking strength and whiteness dropped slightly.
