Problems solved by technology

In fact, in the in-situ mineralization dyeing process of cellulose fibers, if soda ash is used for color fixation, the subsequent in-situ mineralization efficiency will decrease, mainly manifested in the ineffective removal rate of various organic pollutants including residual dyestuffs. High, the color fastness of the dyed product is also lower than that of the traditional dyed product
In addition, in the above-mentioned published invention patents, the post-treatment process disclosed uses dyeing post-treatment auxiliary XAC, dyeing post-treatment auxiliary XBC and dyeing post-treatment auxiliary XYC respectively, and the combination of the above-mentioned post-treatment aids often lead to low mineralization efficiency

Abstract

The invention discloses a cellulose fiber in-situ mineralization dyeing method based on a fixation alkali agent and a mineralization acid agent, and is a supplement and innovation based on dyeing post-processing methods and additives of cellulose fiber in-situ mineralization deep water saving and emission reduction in the invention patent. The cellulose fiber in-situ mineralization dyeing method based on the fixation alkali agent and mineralization acid agent comprises the following steps that the developed fixation alkali agent XGA and the mineralization acid agent XKH are used, so that reactive dye can normally fix the color of cellulose fibers, and the efficiency of an in-situ mineralization link after dyeing further can be improved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to an in-situ mineralized dyeing method for cellulose fibers based on a color-fixing alkaline agent and a mineralizing acid agent. Background technique [0002] In the Chinese invention patent cellulose fiber in-situ mineralization deep water-saving emission reduction dyeing post-treatment method and auxiliary agent (patent number: ZL201510106886.2, publication number: 104695253, publication date: June 10, 2015) Disclosed are specific post-dyeing treatment methods and related auxiliaries used. In the disclosed dyeing process, the dyeing method mentioned therein is a general dyeing method of reactive dyes on cellulose fibers, and the color-fixing alkali agent used in the above dyeing method is generally soda ash. In fact, in the in-situ mineralization dyeing process of cellulose fibers, if soda ash is used for color fixation, the subsequent in-situ m...
