In this paper, The influence of heat set and dyeing on the structure of PTT fiber was investigated by FT-IR, DSC, critical dissolution time. The influence of heat set on the dyeability of PTT fiber was discussed, too. Meanwhile, many experiments on the dyeing performance of PET fiber were carried out. The effect of different dyeing temperature on the uptake and visual color depth value and dyeing characteristics of different dyes with temperature increasing were discussed, and the influence of temperature on the dyeing depth were also evaluated when dyeing for PTT and PET fiber in the same dye bath condition. Especially the kinetics and thermodynamics of dyeing with disperse dyes were mainly studied.

目前，我国对PTT染色性能方面研究报道还少，本文用傅立叶红外光谱、差热分析、临界溶解时间等分析方法研究了热定型和染色对PTT纤维结构的影响，探讨了热定型对PTT纤维可染性的影响，同时进行了多项PTT纤维的基本染色性能试验，探讨了不同染色温度对上染百分率及表观色深值的影响、不同染料的升温上染特性、不同染料的移染性能和染深性能以及PTT和PET纤维同浴染色时染色温度对它们的染色深度的影响。
