【摘要】 就PTT、PET原料选择,纺丝组件设计,复合纺丝工艺及加弹工艺进行探讨。生产结果表明:选择特性黏度0.5～0.6dL/g的PET和特性黏度1.2～1.3dL/g的PTT切片,以40%/60%～50%/50%(PET/PTT)的复合比,可以生产出质量稳定、性能较好的PTT/PET并列型复合长丝,并实现了批量化生产。更多还原

【Abstract】 The raw material selection, spinpack designing, bicomponet spinning technology and texturizing were discussed. The results showed that good quality and better performance side by side PTT/PET composite filaments were made by commercial production with the conditions of PET with IV 0.5～0.6 dL/g, PTT with IV 1.2～1.3 dL/g and PET/PTT composite ratio 40 %/60 %～50 %/50 %.更多还原
