Abstract

The invention provides a deep dyeing promoter for a dyed polyester textile fabric and a preparation method thereof. The deep dyeing promoter is prepared from a cationic emulsifier, a nonionic emulsifier, methyl methacrylate, styrene, acrylonitrile, glycol methacrylate, a fluorine containing monomer, an organic silicon monomer, an initiator and deionized water by using a semi-continuous seed emulsion polymerization method, wherein the organic silicon monomer is added into a pre-emulsion in the second half stage for emulsification and dropwise-adding polymerization to obtain the deep dyeing promoter emulsion with a core-shell structure. The deep dyeing promoter provided by the invention has good deep dyeing effect; meanwhile, the textile fabric treated by using the deep dyeing promoter has good flexibility, stitch slipping resistance and slippage resistance.

Description

technical field [0001] The invention relates to a finishing agent for textiles, in particular to a darkening finishing agent emulsion for dyeing polyester fabrics and a preparation method thereof. Background technique [0002] Polyester is the largest and most widely used synthetic fiber variety in the world. However, because there is no specific dyeing group on the polyester molecular chain and the polarity is small, it is difficult to dye, and the dyeability is poor, and the dye molecules are not easy to enter. , plus polyester has a high refractive index and smooth surface, its dyeing depth is poor, and it needs to be darkened in the finishing process. [0003] Fabric darkening agent, when used in fabric finishing, the auxiliary agent can be adsorbed in large quantities on the surface of the fabric to form deposits, causing uneven pits on the surface of the fabric, so that the light incident on the surface of the fabric will be generated on the deposition layer of the dar...
