Problems solved by technology

[0003] CN103255618A discloses "A Polyester Fabric Deepening Agent Copolymer Emulsion and Its Preparation Method". The invention uses cationic and nonionic emulsifiers to make the emulsion cationic in general, but uses an alkylphenol polyoxyethylene ether (APEO) structure The emulsifier is a chemical banned in the field of textiles, which does not meet the requirements of environmental protection
[0007] Most of the darkening agents are cationic because they neutralize the negative ions on the surface of the fiber during dyeing and improve the affinity between the fiber and the coating and the dye. The darkening effect is not ideal, and the cationic darkening agent has certain limitations in actual use. If anionic additives such as anionic pigment printing adhesives are used in the post-treatment process of the cloth surface, the darkening effect will be obvious. If the drop is worse, foaming and flocculation will occur
[0008] There is no production technology disclosure of non-ionic acrylate darkening agent

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing auxiliaries, in particular to a nonionic acrylate darkening agent used on polyester fabrics and a preparation method thereof. Background technique [0002] Polyester fiber is currently the largest synthetic fiber variety at home and abroad. Polyester fiber has good mechanical properties. The garments made of polyester fiber have a crisp appearance, high strength, good wearing stability, and good anti-corrosion, moth-proof, and abrasion resistance. It is also a simulated silk product. The most preferred fabric. However, due to the unique molecular structure of polyester fiber, the crystallinity of the surface of the fabric is relatively large, especially the development and application of fine denier filaments, resulting in poor dyeability of polyester fiber, especially the poor dyeing depth. Even if the amount of dye is increased, it cannot reach the expected However, it causes problem...
