摘要(Abstract)：
采用POY-DT生产工艺路线,在POY纺丝线和经改造的平衡拉伸机设备上生产出PTT长丝。着重指出了PTT纤维生产在干燥、纺丝、卷绕、平行拉伸上和PET纤维的不同,并结合实例对POY—DT工艺的要求作了探讨。
The PTT DT fiber was produced by POY spinning line and modified parallel drawing equipment. The differences on drying, spinning, winding and parallel drawing between PTT fiber and PET fiber were pointed out. The production process of PTT DT was discussed.
