摘　　要：为实现低碳环保功能性色纺涡流纱的制备,将PHBV改性涤纶、冷轧堆染色棉纤维和普通涤纶混纺,通过两次纤维包混提高纤维的混和均匀度;开清棉工序遵循“勤抓少抓,多松少打,轻梳少落,充分混和,少伤纤维”的工艺原则,梳棉工序遵循“适中定量,加强分梳,柔性梳理,中等隔距,快速转移”的工艺原则,以改善生条质量;选用三道并条工序,采用“轻定量,多并合,中隔距,慢速度,合理牵伸分配”的工艺原则,以提升熟条质量;喷气涡流纺工序根据原料特性,合理设置纺纱速度、喷嘴气压等工艺参数;同时严格控制生产各环节车间的温湿度,减少生产质量波动。最终成功纺出涤纶/棉/PHBV改性涤纶50/35/1519.7 tex喷气涡流纺色纺纱,色纺纱表现出优异的力学性能和良好的抗菌抑菌功能,断裂强度达到18.55 cN/tex,对金黄色葡萄球菌的抑菌率达到97.29%,对大肠杆菌的抑菌率达到98.42%。In order to achieve low-carbon and environmental protection in functional colored vortex spun yarn preparation,blending uniformity of PHBV modified polyester fiber,cold pad-batch dyed cotton fiber and common polyester blended yarn was increased by twice fiber package blending.The process principle of“multiple and light quantitative grasp,more loosening and less beating,light carding and less falling,full blending and less damage to fiber”was followed in opening picking process.The process principle of“moderate weight per unit,strengthening carding,flexible carding,medium gauge and rapid transfer”was followed in the carding process to improve the quality of card sliver.Three drawing processes were selected,and the process principle of“light weight per unit,more doubling,medium gauge,slow delivery speed and reasonable draft distribution”was adopted to improve the quality of drawn sliver.According to the fiber characteristics,process parameters including spinning speed,nozzle pressure and so on were reasonably set in air-jet vortex spinning process.In addition,in order to reduce production fluctuations,the temperature and humidity in each workshop were strictly controlled.Finally,the polyester/cotton/PHBV modified polyester fiber 50/35/15 air-jet vortex colored spun yarn with 19.7 tex was successfully spun.The dyed spun yarn showed excellent mechanical property and better bacteriostatic function.The breaking tenacity was reached up to 18.55 cN/tex.The bacteriostatic rate of staphylococcus aureus was reached 97.29%and the bacteriostatic rate of Escherichia coli was reached 98.42%.
