Problems solved by technology

However, after dyeing, there is still a certain amount of residual dye in the dyeing residual bath and on the dyed fiber, and the discharge of pollutants and a large number of soaping and washing steps are indispensable.
Therefore, the above studies still cannot fundamentally solve the problems of high water consumption and high pollution in cellulose fiber dyeing and processing.
[0006] To sum up, for the dyeing process of cellulose fiber, a feasible new dyeing technology for deep water saving and emission reduction has not been found at home and abroad.

Abstract

The invention discloses a cellulosic fiber in-situ mineralization deep water-saving and 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 dyeing processing on the fabric to be dyed by using a common deying method for the cellulosic fiber, and after dyeing is completed, retaining the residual dyeing liquid; further simultaneously performing in-situ mineralization treatment on the residual dyeing liquid obtained after cellulosic fiber dyeing processing and the dyed fabric by using cellulosic fiber aftertreatment additives XAC, XBC and XYC; storing the residual dyeing liquid obtained after the mineralization treatment as later dyeing water; dehydrating and drying the dyed fabric, thereby completing dyeing and aftertreatment on the fabric. The invention further discloses the cellulosic fiber dyeing aftertreatment additives XAC, XBC and XYC. By adopting the dyeing aftertreatment method disclosed by the invention, the water consumption problem and the wastewater discharge problem in the cellulosic fiber dyeing processing can be fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and specifically relates to the in-situ mineralization and deep water-saving and emission-reducing post-dyeing treatment method for the dyeing residual bath and dyed fibers after dyeing of cellulose fibers. The invention also relates to the above-mentioned in-situ The cellulose fiber dyeing post-treatment auxiliary agent XAC, the cellulose fiber dyeing post-treatment auxiliary agent XBC, and the cellulose fiber dyeing post-treatment auxiliary agent XYC involved in the mineralization and deep water-saving and emission-reducing dyeing post-treatment method. Background technique [0002] A certain amount of residual dyes and residual dyeing auxiliaries often exist in the dyeing residual bath of cellulose fibers after dyeing, and a certain amount of residual dyes also exist on the dyed fibers. In the traditional dyeing process of cellulose fiber, the above-mentioned dyeing residu...
