摘　　要：采用聚对苯二甲酸乙二酯(PET)瓶片和废旧PET布料通过回收工艺生产再生PET和及生PET纤维。PET瓶片可以直接熔融挤出制成纤维,也可以转化成再生PET切片后熔融挤出制成纤维,还可以通过螺杆挤出机增加液相熔体黏度提高再生PET熔体质量。废旧PET纤维可以通过解聚反应、酯交换反应分离回收高纯度再生PET及再生PET纤维。再生PET纤维广泛应用于服装设计领域。Recycling polyethylene terephthalate(PET)and recycling PET fiber are produced by PET bottle flakes and wasted PET cloth.PET bottle flakes can be used to produce PET fiber directly by melting and extrusion,or make chips to produce fiber via melting and extrusion.Recycling PET melt quality can be improved by enhancing the viscosity of liquid-phase melt with screw extruder.Recycling PET and PET fiber with high purity can be recovered from wasted PET fiber via depolymerization and transesterification.Recycling PET fiber has been widely used for clothing design.
