Abstract

The invention discloses a preparation method of a high-fixation-rate nano liquid disperse dye. The method comprises the following steps of: mixing a grinding aid with a certain amount of deionized water to fully swell the grinding aid; adding a disperse dye, propylene glycol, a basic dispersing agent and a wetting agent, carrying out pre-grinding; and adding the residual deionized water; adding ahyperbranched dispersant into the ground system, and perform further grinding; carrying out suction filtration by using a filter screen; adding an anti-flocculating agent and a preservative into a filtrate; and carrying out high-speed shearing emulsification to obtain the high-fixation-rate nano liquid disperse dye. The liquid disperse dye is applied to the printing process of polyester fiber fabric; the fixation rate of the liquid disperse dye on the fabric can be increased; color flooding on the surface of the fabric is prevented; the effect of wash-free printing is achieved; the printed fabric can be endowed with good wearing fastness; the soft hand feeling of the fabric can be guaranteed; and the discharge amount of printing and dyeing wastewater can be reduced.

Description

technical field [0001] The invention belongs to the field of disperse dyes and their preparation and application, in particular to a high-fixation-rate nano-liquid disperse dye and its preparation method and application in printing, especially to the application of the high-fixation-rate nano-liquid disperse dye in polyester wash-free application in printing. Background technique [0002] Polyester is the largest and most widely used synthetic fiber variety in the world. Currently, polyester accounts for more than 60% of the world's synthetic fiber output. Disperse dyes for polyester dyeing are the most important category in the dye industry. Conventional disperse dyes require cumbersome and lengthy post-washing and reduction cleaning processes in the polyester dyeing or printing process in order to obtain better color fastness for fabrics. However, a large amount of printing and dyeing wastewater will be produced in the subsequent cleaning process, which contains a large ...
