摘要/Abstract

摘要：

为提高聚酯纤维的染色性能，采用阳离子染料对ECDP纤维进行染色，系统研究纤维的染色性能。结果表明：ECDP纤维的等温吸附曲线属于L型（Langmuir型）；与常规PET、CDP及腈纶相比，其染色饱和值较高，染色深度可达到染PAN纤维的水平；ECDP纤维的上染曲线均呈S型，纤维在较低的温度下就有一定的上染率，最终上染率也较高；染浴的pH值应控制在4~5左右；升高温度及延长保温时间都能增加纤维的上染率。

Abstract:

In order to improve the dyeing performance of polyester fibers, ECDP fibers were dyed with cationic dyestuff, and their dyeing properties were studied systematically. The results showed that the isothermal adsorption curve of ECDP fibers was in accordance with L-type (Langmuir-type). The dyeing saturation values of ECDP were higher than those of PET, CDP and PAN fibers. Its dyeing depth was comparable to that of PAN. ECDP fibers showed S type adsorption curve, high dye-uptake rate which could be further enhanced by rising the temperature or extending the holding time. The pH of the dye bath should be controlled at around 4 - 5.
