摘要(Abstract)：

采用低温干燥、低温低速短流程纺丝、双道上油、降低纺丝组件压力等方法优化纺丝工艺,并降低热箱温度、牵伸比以及加弹速度等,对原位聚合石墨烯改性涤纶长丝的生产技术进行了研究。试验证明,控制石墨烯切片干燥后含水率在2.5×10~(-5)～3.0×10~(-5),纺丝温度284～288℃,组件压力11～12 MPa,纺丝速度2 700～3 000 m/min,假捻变形第一热箱温度185～190℃,第二热箱165～170℃,牵伸比1.700～1.730,卷绕速度620～650 m/min,D/Y比为1.680～1.710,可以制备出使用性能良好、功能性强的石墨烯改性细旦涤纶拉伸变形丝(DTY),其织物具有抗菌抑螨、远红外发热、保暖、负离子保健等功能。
The spinning process was optimized by low temperature drying, low temperature, low speed and short process spinning, double channel oil feeding, reducing the pressure of the spinneret assembly, and the production technology of in-situ polymerized graphene-modified polyester filament was studied by reducing the heat box temperature, draft ratio and texturing speed. Experimental results show that after the drying of graphene slices, the moisture content is 2.5×10~(-5)～3×10~(-5), the spinning temperature is 284～288 ℃, the component pressure is 11～12 MPa, the spinning speed is 2 700～3 000 m/min, the temperature of the first heat box for false twist deformation is 185～190 ℃, the second heat box is 165～170 ℃, the draft ratio is 1.700～1.730, texturing speed is 620～650 m/min, the D/Y ratio is 1.680～1.710, graphene-modified fine denier polyester draw textured yarn(DTY) with good performance and strong functionality can be produced.The fabric has antibacterial and mite inhibition, far-infrared heating, heat preservation, negative ion health care and other functions.
