摘要
为了提高界面结合能力,采用空气等离子体对芳纶纤维表面进行改性,通过扫描电子显微镜观察处理前后纤维表面形貌的变化情况,对纤维力学性能及摩擦性能进行测试,优选出最佳处理工艺。进一步研究了纤维表面改性处理方式对纤维集合体力学性能和防刺性能的影响。结果表明:表面改性后芳纶纤维的摩擦系数增大,但强力有所下降,空气等离子体处理最佳条件为50Pa、50W处理5min。芳纶纤维表面经过等离子体改性后,无纺布锥刺的最大压缩载荷同比未处理样品提高了5.27%。
In order to improve the interfacial bonding ability,aramid fiber surface was modified by air plasma.The surface morphology of fibers was observed by SEM.The mechanical and tribological properties of fibers were tested to find the optimum treatment process.Then the effect of surface modification on the mechanical properties and stab resistance of fiber aggregate was investigated.The results showed that the friction coefficient of fibers was improved and the strength was decreased after surface modification.The optimum conditions of air plasma treatment were 50 Pa pressure,50 W power and 5 min treatment duration.The awl pierce maximum compression load of non-woven fabrics was increased by 5.27% compared to the untreated sample.
