摘要/Abstract

摘要： 由于涤纶长丝、微孔涤纶两种纤维的纤维表面及性能有很大的差别，因此即使同浴染色也会出现色光不一致的现象。本课题通过耐碱性试验，确定了涤纶长丝及微孔涤纶的减量氧漂前处理工艺为：浴比1：30，烧碱浓度6g/L，高温去油剂0.4g/L，在1300C处理20min；为了减小两组分纤维的色差，通过分散染料筛选，确定了使两组份纤维表面得色深度K/S值相对较大，且色差ΔE相对较小、同色性较好的三原色分散染料：JRB兰、JFG黄、JFRB红，并且分别探讨了染料用量、染色时间、染色温度、染色pH值四个因素对涤纶长丝及微孔涤纶纤维染色同色性的影响。

Abstract: Because of the surface and the performance of polyester filament and microporous modified PET are very different, which lead to the inconsistent shade when even dying with one-bath process. Identified the reduction of oxygen bleaching pre-treatment process of polyester filament and microporous modified PET by alkali resistance tests: Ratio 1:30 , concentration of caustic soda 6g / L, degreasers of high temperature 0.4g / L,130℃ degrees for 20min; In order to reduce the inconsistent shade , filtering the disperse dyes, identified the tricolor dyes: JRB blue, JFG yellow, JFRB red, which gives the two fiber relatively higher surface color depth value K/S, smaller color difference Δ E , and the better union dying. And also discussed the impact of dye concentration , dyeing time , dyeing temperature , dyeing pH value on union dying of the polyester filament and microporous modified PET fiber.

Key words: polyester filament, microporous polyester fiber, one-bath process, homochromy
