氨基甲酸酯法纺制环境友好型抗菌纤维素纤维的研究

纤维素氨基甲酸酯(简称CC)是纤维素与尿素的反应产物,具有安全无毒、易运输、易成纤等特点,是替代粘胶工艺中纤维素黄酸酯最有潜力的中间产品,CC法制造纤维素纤维被认为是改造粘胶厂以及减少和消除环境污染问题的良好途径之一。制备水溶性O-羟乙基壳聚糖,并与纤维素氨基甲酸酯共溶于NaOH溶液中,通过环境友好的CC工艺纺制抗菌性纤维素纤维并对其力学性能和抗菌性能进行了研究。结果表明:含有O-羟乙基壳聚糖的纤维素氨基甲酸酯纺丝过程顺利,制得的纤维具有良好的力学性能,且表现出明显的抗菌性和抗菌耐洗涤性。

Study on eco-friendly antibacterial cellulose carbamate fiber

Cellulose carbamate(CC),a kind of derivative of cellulose,is considered as the most potential intermediate to instead of cellulose viscose.It is introduced that water-soluble O-hydroxyethyl chitosan (HECS) was synthesized and dissolved in NaOH solution to spin cellulose/HECS blend fiber by CC process,also the physical and antibacterial properties were examined.The results show that the introduction of HECS has slight effect on physics properties,and the fibers show antibacterial activity against E.coli.
