Abstract

The invention discloses a polyester fiber disperse dye low-temperature coloring accelerant BENTE and a technique. The accelerant BENTE comprises the following components by the weight percentage: 85 to 97 percent of organic compound BLB and 3 to 15 percent of compound emulsifier. The compound emulsifier comprises the components with the following weight percentage: 98 to 60 percent of hydrophilic nonionic surface active agent, 0 to 30 percent of hydrophobic nonionic surface active agent, and 2 to 10 percent of assistant emulsifier. The coloring technique thereof is as follows: 0.1 to 5 percent (o.w.f) of disperse dye and 1 to 10 percent (o.w.f) of the accelerant BENTE are dyed under the temperature between 50 and 60 DEG C with the pH value of 4.5 to 7 and a bath ratio of 1:10 to 1:50; the temperature is raised to the temperature between 90 and 110 DEG C at a speed of 2 DEG C / min and then the temperature is maintained for 60 and 80 min. The coloring technique not only is convenient to be used, but also endows the coloring benefit of the coloring stage of the polyester fiber disperse dye, lowering the coloring temperature and reduces pollution and cost.

Description

technical field [0001] The present invention relates to a kind of accelerator BENTE with aromatic ester compound as the main component, which is suitable for the low-temperature dyeing of polyester fiber disperse dyes. The accelerator BENTE is used to reduce the dyeing temperature of polyester fiber and achieve a better dyeing effect. . Background technique [0002] Polyester is a hydrophobic synthetic fiber with poor dyeability under normal pressure. The traditional polyester dyeing process mainly includes high temperature and high pressure dyeing, hot melt method, carrier dyeing and so on. High-temperature and high-pressure dyeing requires high-pressure-resistant processing equipment, consumes a lot of heat energy, and has the disadvantage of easy precipitation of oligomers; the hot-melt method consumes a lot of energy, and the hand feeling and color brightness of the dyed product are not ideal; the carrier used in the carrier method has unpleasant Odor or toxicity, diff...
