摘要
为了完善PTT纤维的染整加工理论，确保PTT纤维织物的染色质量，针对分散染料对PTT、PET聚酯纤维染色差异问题，选用常用的中低温、高温型2类分散染料分别对PTT、PET织物染色，测试其在不同染色温度下及其在同浴染色时的上染率、K／S值、染色牢度，研究不同染料在PTT、PET织物上的染色机制及最佳染色工艺。结果表明：PTT与PET纤维相比，PTT纤维的染色性能更好；采用不同类型分散染料染色，PTT的最佳染色温度不同；PTT、PET纤维在100～110℃同浴染色可得到异色或闪色效果，在120～130℃同浴染色可获得同色效果。
In order to consummate the dyeing and finishing theory of PTT fiber, ensure the dyeing quality of PTT fabrics, this paper has investigated optima dyeing process and dyeing mechanism of disperse dyes to PTT and PET fabrics through dyeing them with two different types of disperse dyes and measuring the dye-uptake, K/S value and colorfastness, and discussed the difference of dyeing behaviour for PTT and PET polyester fibers. The result has showed that the dyeing behaviour of PTT fiber is better than that of PET. PTT fiber is a polyester fiber with excellent dyeability. The optimal dyeing temperature varies with disperse dyes used for dyeing PTT fibers; The two-tone effects of PTT and PET fibers will be obtained in one bath dyeing at 100 - 110 ℃, and the union-colour effects of PTT and PET fibers will be obtained in one bath dyeing at 120 - 130 ℃.
