Abstract

The invention discloses a method for polyamide fiber in-situ mineralization deep water-saving and emission-reducing dyeing after-treatment. The method comprises the following steps: putting a to-be-dyed textile into dyeing equipment, adding dyeing water, and keeping dye-bath cycling to perform preparation before dyeing; performing dyeing processing on the to-be-dyed textile according to a general dyeing method of polyamide fibers; synchronously performing in-situ mineralization treatment on a dyeing residual bath and the dyed textile by using polyamide fiber dyeing after-treatment auxiliary agents XAJ, XBJ and XYJ; storing the dyeing residual bath subjected to the mineralization treatment to serve as water for subsequent dyeing; and dehydrating and drying the dyed textile to finish the whole dyeing after-treatment processing. The invention also discloses the polyamide fiber dyeing after-treatment auxiliary agents XAJ, XBJ and XYJ. By adopting the method for the polyamide fiber in-situ mineralization deep water-saving and emission-reducing dyeing after-treatment, the problems of water consumption and wastewater discharge during dyeing processing of the polyamide fibers are fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and specifically relates to a post-dyeing method for in-situ mineralization of polyamide fibers, which is deeply water-saving and emission-reducing. XAJ, polyamide fiber dyeing post-treatment auxiliary XBJ and polyamide fiber dyeing post-treatment auxiliary XYJ. Background technique [0002] There is often a certain amount of residual dye and residual dyeing auxiliaries in the dyeing residual bath of polyamide fiber after dyeing, and there is also a certain amount of residual dye on the dyed fiber. In the traditional dyeing process of polyamide 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. In addition, in order to ensure the color fastness of the dyed fiber, soaping and washing must be carried out. In general, including dyeing, soaping and was...
