摘要
将聚丙烯 ,纳米陶瓷粒子 ,沸石混合造粒制得抗菌母粒 ,聚丙烯切片与抗菌母粒共混熔融纺丝 ,得到纳米复合抗菌丙纶。测试了纤维的抗菌性能、热性能、力学性能 ,并对纳米粒子及纤维进行了扫描电镜分析。结果表明 :纳米抗菌剂最佳含量在 0 .8%左右 ,纤维抑菌率达 90 %以上 ,且耐久性好。纤维结晶度下降 ,而熔点提高。纳米抗菌剂在纤维中有少量凝聚 ,纤维断裂强度略有降低 。
Polypropylene was mixed with nano\|ceramic particles and zeolite and granulated to produce antibacterial masterbatch. Nanocomposite antibacterial PP fiber was prepared by melt blend spinning of polypropylene chips and antibacterial masterbatch. The antibacterial, thermal and mechanical properties were measured. The dimension of nanoparticles and its dispersion in PP composite were observed by SEM. The results showed that the optimum active content of added nanoparticles was about 0.8%, and the bacteriostatic rate of PP fiber was higher than 90% with good lasting quality. The fiber's crystalline degree decreased while T m increased. The breaking strength of the finished fiber decreased slightly due to some coacervation of antibacterial nanoparticles in the fiber, but can meet the needs of textile process for apparel.
