摘　　要：为了进一步提高锦纶6的综合性能,文章通过熔融纺丝制得石墨烯/锦纶6(PA6)预取向丝(POY),然后将经石墨烯改性的PA6 POY拉伸假捻变形得到具有优异性能的PA6 DTY,并进一步研究了不同规格的石墨烯改性PA6 POY在制备过程中石墨烯含量、喷丝板、纺丝温度等工艺条件对其性能的影响,及后续DTY加工过程中加弹速度、拉伸比、D/Y等工艺参数对成品丝性能的影响。经表征,发现石墨烯均匀分散于基体PA6中,石墨烯/PA6 DTY具有优异的电导率、力学性能及抗菌性能。In order to further improve the comprehensive performance of PA6 filament,graphene/PA6 POY filament was prepared by melt spinning,and then PA6 DTY filament with excellent properties was produced by drawing and false twisting the modified PA6 POY filament.In addition,the effects of graphene content,spinneret,spinning temperature,and other process conditions on the preparation of graphene/PA6 POY filament with different linear densities were discussed.And the speed of texturing,draw ratio,and D/Y in the subsequent texturing in the DTY process were also discussed.The results showed that graphene was uniformly dispersed in the PA6 matrix,and graphene/PA6 DTY had excellent electrical conductivity,mechanical properties,and antibacterial properties.
