Resumen

The gradient in the change of temperature of the dyeing process is a variable that must be controlled to optimize the dyeing of polyester fibers. The aim of this paper is to evaluate the gradient in the change of temperature on the dyeing of polyester fibers. There were developed three tests of polyester fibers dyeing process considering that the dye curve is the same in all three tests, in which only varies the gradient in the temperature rise. The tests were performed with 100 % polyester fabric 150/34, samples of 100g, red dye (light shade - 1.760 gr Terasil SD Yellow and Red Terasil SD 0.192 gr). The tests were developed in the Mathis machine, the hydroextractor and stove for drying the samples. The results show that the use of dispersants and anti-breakage agents works to prevent breakdowns and improve the matching colors, but still high gradient causes an increased dye migration and breaks in the fibers, but at low gradients (2 ° C / min) the diffusion and dyeing quality is better, and thus avoids reprocessing in the dyeing step.
