Problems solved by technology

The non-steaming and cleaning superfine disperse dye color paste provided by the present invention does not need to adopt the high bath ratio required by high temperature and high pressure in the traditional method during pad dyeing, nor does it need to use reduction cleaning and water washing, thereby solving the traditional high temperature problem. In high-pressure dyeing, the water consumption is large, the process is complicated, the energy consumption is large, and the environmental pollution and economic problems caused by the large amount of sewage discharge

Abstract

The invention discloses a steam-cleaning-free ultrafine disperse dye color paste preparation method, and belongs to the field of polyester short-flow dyeing. Dispersing agents are added into dispersedyes and grinded to prepare ultrafine disperse dye dispersions, the ultrafine disperse dye dispersions are mixed with migration inhibitors, curing agents, penetrating agents and high-temperature leveling agents to prepare ultrafine disperse dye color paste. The color paste can be used for steam-cleaning-free padding and dyeing of polyester fabrics, and fabric dyeing fastness improving effects areobvious. The preparation method is simple in process, strong in operability and suitable for batch dyeing treatment of the polyester fabrics, water is saved, and the requirement of modern industrial environmental protection is met.

Description

technical field [0001] The invention relates to a preparation method of non-steaming and washing superfine disperse dye paste, which belongs to the field of polyester short-process dyeing. Background technique [0002] Disperse dyes should be ground into fine particles of 0.1-2.0 μm with the help of dispersants, and then dispersed and suspended in the dye bath as fine particles. The dye bath of disperse dyes is a suspension composed of these fine particle dye crystals. The solubility of disperse dyes is extremely important for dyeing. Disperse dyes will also undergo crystal lattice growth in the dyeing solution, making the dyeing solution become a supersaturated solution and precipitate out, and sometimes crystal transformation will occur during the dyeing process. Therefore, when the dye is commercialized, often Add some additives to prevent these phenomena from happening. [0003] Disperse dyes are the main colorant for dyeing and printing acetate fiber and polyester fib...
