植物中药改性粘胶纤维的制备及性能研究
|
摘要
探讨一种植物中药改性粘胶纤维的基本性能和抗菌性。将植物中药蛇床子、仙茅、苦参和菟丝子等提取物水溶液按一定比例混合后与粘胶纺丝液共混制备了植物中药改性粘胶纤维。对该改性粘胶纤维的结晶度、取向度、力学性能、吸湿性能、抑菌性以及蛇床子素和仙茅苷的含量进行了测试。结果表明:与普通粘胶纤维相比,植物中药改性粘胶纤维的结晶度有所增大,取向度有所减小,断裂强度、断裂伸长率减小,吸湿性能有所增加;该纤维对金黄色葡萄球菌、大肠杆菌和白色念珠菌的抑菌率分别为98.9%、98.8%和89.0%;纤维中蛇床子素的含量为5.12mg/kg,仙茅苷的含量为0.6mg/kg。认为:所制得的植物中药改性粘胶纤维具有良好的抗菌保健功效。
The basic properties and antibacterial property of a traditional Chinese medicine plant modified viscose fiber were discussed.The traditional Chinese medicine plant modified viscose fiber was produced by mixing viscose spinning solution with the water solution of the extracts of traditional Chinese medicine plant from fructus cnidii,rhizoma curculiginis,sophora flavescens,cuscuta chinensis Lamat and so on with a certain mixing ratio.The properties of modified viscose fiber including crystalline degree,orientation degree,mechanical property,moisture absorption and anti-bacterial properties together with the contents of cnidium lactone and curculigoside were tested.The test results showed that the crystalline degree of traditional Chinese medicine plant modified viscose fiber was increased compared with normal viscose fibers,the orientation degree was reduced,the breaking strength and breaking elongation were decreased,the moisture absorption was improved.The antibacterial rates of the fiber against staphylococcus aureus,escherichia coli and Candida albicans were 98.9%,98.8% and 89.0% respectively.The cnidium lactone contents in fibers was 5.12 mg/kg,the curculigoside content was 0.6 mg/kg.It is considered that the traditional Chinese medicine plant modified viscose fiber has better healthy efficacy.
