杜邦干热拉伸工艺对涤纶短纤维干热收缩率的影响

Effect of DuPont dry drawing process on the drying shrinkage of polyester staple

通过后加工工序的优化来降低1.33 dtex×38 mm涤纶短纤维的180℃干热收缩率。指出:合适的紧张热定型温度、冷却和松弛热定型的烘燥效果可以降低该纤维的干热收缩率。

Effect of DuPont dry drawing process on the drying shrinkage of polyester staple ZHANG Hai-bin,CHEN Ming （ Luoyang Shihua Through the afterprocessing optimization,the 180℃ drying shrinkage of 1.33 dtex × 38 mm polyester staple was reduced. It was pointed out that by selecting the suitable tension-setting temperature, cooling and relaxationsetting drying results, the fiber drying shrinkage can be reduced.
