Abstract

The invention discloses a preparation method and application of a leveling agent XDR for high-temperature and high-pressure dyeing of polyester fibers by disperse dyes. The preparation method is mainly characterized in that fatty alcohol-polyoxyethylene ether, alkyl sodium sulfonate, alkyl sulfate sodium, fatty amine polyoxyethylene ether, urea and purified water are uniformly mixed to obtain the leveling agent XDR for high-temperature and high-pressure dyeing of polyester fibers by disperse dyes. The invention also discloses a method for dyeing polyester fibers and polyester fiber blended products by use of the leveling agent XDR for high-temperature and high-pressure dyeing of polyester fibers by disperse dyes. After adoption of the prepared leveling agent XDR for high-temperature and high-pressure dyeing of polyester fibers by disperse dyes, the oriented adsorption density of surfactant molecules on the surfaces of disperse dyes particles is remarkably improved, the interfacial tension between the dye particles and water and the average grain diameters of the dyes particles are obviously reduced, the solubility of the dyes and the dyeing percentage of the dyes to the fibers are remarkably improved, and agglomeration of the dyes and nonuniform dyeing can be dramatically reduced.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and specifically relates to a preparation method of a high-temperature and high-pressure dyeing leveling agent XDR for polyester fibers with disperse dyes. And its application in the dyeing process of blended products. Background technique [0002] When disperse dyes are used to dye polyester fibers and their blended products, there are usually problems of poor level dyeing and relatively low dyeing percentage of the fibers, and these problems often easily lead to unqualified dyeing quality and low dye utilization rate. Not high and dyeing wastewater CODcr higher consequences. [0003] In the production process of commercial disperse dyes, in order to ensure fine and uniform dye particles and dispersion stability under high temperature conditions in the dye bath, dispersants with anionic surfactants as the main body are often added. [0004] In the dyeing process, in order ...
