分散染料常压低温易染异形聚酯纤维的研制

Study of disperse dyes normal pressure low temperature easy-to-dye profiled PET fiber

选用改性共聚酯切片(EDDP),在现有POY两部位高速纺实验机上进行异形易染纤维的纺丝实验,确定了最佳工艺条件。试验表明异形EDDP纤维可常压沸染,色谱齐全,性能优良。

The modified copolyester chip was selected. The spinning experiment of easy-to-dye profiled PET fiber was carried on the exist POY two positions high speed spinning machine. The optimum process conditions were determined. The experiments showed that the EDDP fiber can be dyed under normal pressue. The products had a complete range of colour spectrum and good performances.
