Abstract

The invention discloses a dispersed dye in-situ mineralization and deep water conservation emission reduction dyeing aftertreatment method which comprises the following steps: firstly, putting a fabric to be dyed into dyeing equipment, adding dyeing water into the dyeing equipment, and keeping circulation of a dye bath; performing conventional dyeing processing on the fabric to be dyed in the dyeing equipment by using dispersed dye and using a high-temperature high-pressure dyeing method, and after dyeing is completed, retaining the residual dyeing bath; further simultaneously performing in-situ mineralization treatment on the residual dyeing bath and the dyed fabric; finally storing the residual dyeing bath obtained after the treatment as later dyeing water, and dehydrating and drying the dyed fabric, thereby completing the whole aftertreatment process. The invention further discloses three additives used in the dyeing aftertreatment method. By adopting the aftertreatment method disclosed by the invention, later reduction washing and water washing after dyeing can be avoided, the residual dyeing liquid after the in-situ mineralization treatment can be further reused in later dyeing treatment, and thus the water consumption and the pollutant discharge amount of the whole dyeing treatment can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing methods, and relates to a post-dyeing treatment method for in-situ mineralization of disperse dyes, deep water saving and emission reduction, and the post-dyeing treatment of three disperse dyes used in the above-mentioned post-dyeing treatment method Auxiliaries XBD, XYD, XCD and their respective preparation methods. Background technique [0002] The residual dyeing bath after dyeing polyester fibers and polyester fibers and other fiber blended products with disperse dyes often contains a large amount of residual dyes and residual surfactants, and there are also residual dyes that have not been fixed on the surface of the dyed fibers . The discharge of dyeing residue can cause higher dyeing wastewater treatment costs, and there are hidden dangers of environmental pollution. In addition, in order to ensure the color fastness, reduction cleaning and corresponding washing proc...
