摘　　要：以低熔点聚酯(COPET)为皮、普通聚酯(PET)为芯,介绍了开发COPET/PET低熔点皮芯型复合短纤维的复合纺丝生产工艺,探讨了COPET原料选择、COPET切片输送与干燥、真空双螺杆挤压机、纺丝组件、纺丝温度、卷曲机、烘干机和打包机等工艺条件和设备对生产的影响。结果表明,如选择合适的工艺和设备,可以生产出质量稳定、完全可以取代进口的低熔点皮芯型涤纶短纤维。The production process of low melting point polyester staple fiber in which COPET is for the sheath and PET is for the core is introduced. The effect of COPET chips selection, COPET/PET ratio, chips transport and drying, vacuum twin screw extruder, spin pack, spinning temperature, crimping machine, dryer and bate press on production are discussed. The results show that the low melting point fiber with quality can replace imported product via proper production process.
