Problems solved by technology

The disadvantage of this method is that the amount of sodium salt polymerizable emulsifier COPS-1 and SVS in the emulsification system is too high, which affects the water resistance of the emulsion film, and the dye migration of the emulsion film is serious in a humid environment; and HA, SIPOMER WAMⅡ, V-70M composed of one or more crosslinking systems, the emulsion prepared by it has slow self-crosslinking speed at room temperature and low elongation at break, which is not suitable for application in textile pigment printing

Abstract

The invention relates to a polyacrylate emulsion for delaying dye migration, comprising the following components: anti-dye migration functional monomer, crosslinking monomer A, crosslinking monomer B, post-crosslinking monomer C, anionic ammonium salt emulsification agent, sodium salt emulsifier, polymerized monomer, buffering agent, initiator, post-elimination agent, pH regulator, deionized water; wherein, the cross-linking monomer B is ethyl methacrylate acetoacetate, diacetone propylene Any one or a combination of at least two of amides; the post-crosslinking monomer C is any one or a combination of at least two of adipic dihydrazide and hexamethylenediamine. The polyacrylate emulsion for delaying dye migration provided by the present invention is used on fabrics such as polyester with severe dye migration. During the service life of the textile, the printing coating will not appear color spots and streaks caused by dye migration, and the color of the coating will be maintained. It has a good application prospect in the fields of leather, textile, paint and so on.

Description

technical field [0001] The invention belongs to the field of printing and dyeing of textiles, and in particular relates to a polyacrylate emulsion for delaying dye migration and a preparation method thereof. Background technique [0002] With the development of the textile industry, various pigment printings emerge in endlessly, and the quality is also uneven. Pigment printing uses adhesives to bond insoluble pigments and fillers to textiles to form coatings with different patterns and shapes. It has the advantages of convenient operation, complete color spectrum, energy saving and environmental protection. In the actual production process, when printing polyester and polyester / cotton fabrics, dye migration will occur during curing in the drying tunnel, which will cause yellow spots, black spots or other color patterns on the coating, which will seriously affect the printing coating. The appearance is commonly called "sublimation" in the printing material industry. The rea...
