Abstract

The invention discloses an in-situ mineralization and water-saving emission-reduction dyeing post-treatment method for polyacrylonitrile fibers. The method comprises the following steps: putting a to-be-dyed textile into dyeing equipment, adding dyeing water, keeping dye bath recycling, and making preparations before dyeing; performing dyeing processing on the to-be-dyed textile with a general polyacrylonitrile fiber dyeing method, and not discharging dyeing residual liquid after finishing dyeing; performing mineralization treatment on the dyed textile by utilizing polyacrylonitrile fiber dyeing post-treatment auxiliary agents XAQ, XBQ and XYQ; performing treatment on the obtained residual dyeing bath and the dyed textile, and finishing the whole dyeing post-treatment process. The invention further relates to respective formulae and preparation methods of the polyacrylonitrile fiber dyeing post-treatment auxiliary agents XAQ, XBQ and XYQ. The in-situ mineralization and deep water-saving emission-reduction dyeing post-treatment method for the polyacrylonitrile fibers and the auxiliary agents solve problems of high water consumption and high wastewater discharge amount in a polyacrylonitrile fiber dyeing processing process.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and specifically relates to a method for in-situ mineralization and deep water-saving and emission-reducing post-dyeing treatment of the dyed residual bath and dyed fibers after dyeing of polyacrylonitrile fibers. The invention also relates to the above-mentioned dyeing method Three kinds of post-treatment auxiliaries XAQ, XBQ and XYQ used in the post-treatment method for polyacrylonitrile fiber dyeing. Background technique [0002] There is often a certain amount of residual dye and residual dyeing auxiliaries in the dyeing residual bath of polyacrylonitrile fiber after dyeing, and there is also a certain amount of residual dye on the dyed fiber. In the traditional dyeing process of polyacrylonitrile fibers, the above-mentioned residual dyeing bath must be discharged, resulting in high dyeing wastewater treatment costs, and there are hidden dangers of environmental pollution...
