摘要(Abstract)：

用硅烷偶联剂处理过的载银纳米氧化锌抗菌剂与尼龙6切片共混制得抗菌尼龙6母粒,通过熔融共混纺丝制得抗菌剂含量不同的抗菌尼龙6纤维。采用视频接触角测量仪、扫描电子显微镜、通用材料试验机、差示扫描量热仪等对抗菌剂表面改性效果及抗菌尼龙6纤维的结构形态、力学性能及结晶性能等进行了研究。结果表明:修饰后的抗菌剂表面呈疏水性,改善了与尼龙6基体的相容性,在尼龙6基体中均匀分散;与纯尼龙6纤维相比,抗菌尼龙6纤维的结晶温度和结晶速率有所提高,结晶度略有降低;抗菌尼龙6纤维的力学性能稍有下降;对大肠杆菌、金黄色葡萄球菌的杀菌率均达97%以上。
An antibacterial nylon 6 fiber with different antibacterial agent content was produced by meltblending spinning from masterbatch of nylon 6 chips and antibacterial agent of nano-ZnO/Ag modified with silane coupling agent. The surface modification effect, the structural morphology, mechanical performance and crystallization behaviors of composite fibers were measured by SEM, universal material testing machine and DSC. The result showed that the surface of nano-ZnO/Ag powders modified by silane coupling agent was hydrophobic. The modified nano-ZnO/Ag had a better compatibility with nylon 6 and uniform dispersion in antibacterial nylon 6 fiber. Compared with the pure nylon 6 fiber, the crystallization temperature and crystallization rate of nano-composites increased, but the crystallinity and mechanical properties of the antibacterial nylon 6 fiber dropped slightly, and antibacterial nylon 6 fiber had the antibacterial efficiency against staphylococcus aureus and coliform bacillus above 97 %.
