摘要:
针对真丝织物易皱、抗菌性能差的问题,采用低温氧等离子体对真丝织物进行预处理,再用壳聚糖、柠檬酸溶液进行二浸二轧抗皱整理。对整理后的真丝织物进行力学性能和白度测试,探讨了有关工艺因素对整理效果的影响,确定了等离子体—壳聚糖对真丝织物抗皱整理的工艺。经整理后真丝织物的抗皱性能有较大提高,折皱回复角可提高50°左右,断裂强力和白度略有下降。结果表明,真丝织物经低温氧等离子体—壳聚糖联合整理后,壳聚糖与真丝纤维发生了接枝,故其折皱回复性能得以提高,纤维的结晶度有所下降。

Abstract:
For the poor wrinkle-resistant and poor antibacterial properties performance, silk fabrics were treated with low-temperature oxygen plasma before coordinated by chitosan-citric acid solution through double-dip-double-nip. The factors influenced on finishing results were studied and the anti-crease finishing process was obtained. The wrinkle-resistant properties of the finished fabrics were improved greatly and crease recovery angle could be improved more than 50o, while the breaking strength and the whiteness declined slightly. The results showed that the chemical crosslinking reaction occurred between chitosan and silk fiber when silk fabrics were carried out plasma-chitosan compound finishing, so the crease recovery performance was improved, and the crystallinity of the finished silk fabrics slightly decreased.
Key words:  silk fabrics  low-temperature oxygen plasma  chitosan  wrinkle resistance
