摘要(Abstract):

将不同比例的聚六亚甲基胍盐酸盐(PHMG)与生物基聚酰胺56(PA56)共混,形成PA56/PHMG共混体系,并通过熔融纺丝的方法制备了抗菌PA56纤维。对PA56/PHMG共混体系的相容性、热性能和抗菌性能,抗菌PA56纤维的力学性能和抗菌性能等进行了表征和分析。通过SEM对PA56/PHMG共混体系的表面形态研究表明,PHMG以微小的颗粒分散在PA56中,没有出现相分离现象,两者具有很好的相容性。DSC、TGA和黏度测试表明,随着PHMG添加量增加,PA56/PHMG共混体系熔点、热分解温度、黏度降低,但总体影响不大,可以应用于后续的纺丝加工。PA56/PHMG共混纤维可纺性良好,纤维力学性能随着PHMG添加量增加而下降。PA56/PHMG共混体系及其纤维都表现出优异的抗菌性能,当PHMG添加量达到2%时,抑菌率可达到99.9%,具有非常优异的抗菌效果。
Polyhexamethylene guanidine hydrochloride(PHMG) with different proportions was blended with polyamide 56(PA56) to form PA56/PHMG blends system, and antibacterial PA56 fibers were prepared by melt spinning. The compatibility, thermal and antibacterial properties of PA56/PHMG blends, and the mechanical and antibacterial properties of antibacterial PA56 fibers were characterized and analyzed. The surface morphology of PA56/PHMG blends system was studied by SEM. The results showed that PHMG was dispersed in PA56 with tiny particles, no phase separation occurred, and the two blends had good compatibility. The results of DSC, TGA and viscosity showed that the melting point, thermal decomposition temperature and viscosity of PA56/PHMG blends decreased with the increase of PHMG content. The spinnability of PA56/PHMG blend fiber was good, and the mechanical properties of the fiber decreased with the increase of PHMG content. Both PA56/PHMG blends and its fiber showed excellent antibacterial performance.When the amount of PHMG was 2%, the antibacterial rate could reach 99.9%, had a very excellent antibacterial effect.
