抗菌防螨防霉功能改性粘胶纤维的制备及其性能
|
摘要
为制备兼具抗菌、防螨、防霉功能且耐久性的功能性粘胶纤维,利用水溶解制备的植物中药山苍子和小茴香提取物溶液,以及由百里香精油制备的微胶囊与粘胶纤维纺丝液进行共混,通过湿法纺丝制备抗菌防螨防霉功能改性粘胶纤维。借助扫描电子显微镜、傅里叶红外光谱仪、X射线衍射仪、单纤强力仪以及抗菌防螨防霉相关测试仪对改性粘胶纤维的结构和性能进行表征与分析。结果表明:与普通粘胶纤维相比,制备的改性粘胶纤维的晶胞结构没有改变,结晶度和取向度分别为41. 3%、77. 1%,与普通粘胶纤维基本一致;改性粘胶纤维纵横向形态无显著变化,断裂伸长率有所增加,但断裂强度略有降低,由该纤维制成的非织造布具有良好的抗菌、防螨、防霉功能及耐水洗性能。
In order to prepare functional viscose fiber with antibacterial,anti-mite and anti-mildew functions and durability,the extract solution of traditional Chinese medicine Litsea cubeba and Foeniculum vulgare prepared by water dissolution and the thyme essential oil microcapsule were blended with viscose spinning solution. Then the modified viscose fiber with antibacterial,anti-mite and anti-mildew functions was prepared by wet spinning. The structure and properties of the fiber were characterized by scanning electron microscopy,Fourier infrared spectroscopy,X-ray diffraction,single fiber strength tester and antibacterial,anti-mite and anti-mildew related testing instruments. The results show that compared with the ordinary viscose fiber,the crystal cell structure of the modified viscose fiber is not changed,and the crystallinity and orientation are 41. 3% and 77. 1%,respectively,which are in accordance with the common viscose fiber. The nonwovens made of the fibers have good anti-bacterial,anti-mite and antimildew functions and wash resistance.
