摘要
文章主要研究了复合导电聚酰胺单丝的纺丝及后拉伸工艺,采用差示扫描量热仪(DSC)对聚酰胺(PA6)切片进行了测试,确定了纺丝温度;采用了一定比例的导电母粒与PA6切片进行皮芯复合纺丝,通过对导电单丝力学性能、导电性能的测试,研究了复合比例、冷却温度以及后拉伸工艺对单丝断裂强度、断裂伸长率以及表面电阻的影响.结果表明:皮层导电母粒含量的增加会使单丝的可纺性变差,当复合比例为20∶80时,导电单丝具有较好的力学性能及导电性能,最终确定后续工艺,即冷却温度为40℃,拉伸倍率为3.5,一级拉伸温度为95℃,二级拉伸温度为160℃.
Abstract
This paper mainly studied the spinning and post-stretching process of composite conductive poiyamide monofilament,tested the polyamide(PA6)chips with differential scanning calorimeter(DSC)and determined the spinning temperature.A certain proportion of conductive masterbatch and PA6 chips were used for leather core composite spinning,and the effects of composite ratio,cooling temperature and post-stretching process on the breaking strength,elongation at break and surface resistance of the monofilament were studied through the testing of the mechanical properties and conductivity of the conductive monofilament.The results showed that the increase of conductive masterbatch content in the cortex made the spinnability of the monofilament worse,and the conductive monofilament had better mechanical and electrical conductive properties when the composite ratio was 20∶80.Finally,it was determined that the follow-up processes were a cooling temperature of 40℃,a stretching rate of 3.5,a first-stage stretching temperature of 95℃,and a second-stage stretching temperature of 160℃.
