Abstract

The invention discloses a polyester fiber treating agent prepared from hydroxyethyl methylacrylate, and relates to the technical field of chemical industries. The polyester fiber treating agent is prepared from the following raw materials in parts by weight: 15-20 parts of hydroxyethyl methylacrylate, 10-15 parts of polyvinyl alcohol, 5-10 parts of glycidyl methacrylate, 3-6 parts of chlorinated polyvinyl chloride, 3-6 parts of polyvinyl acetate, 2-4 parts of hydrogenated ester gum, 2-4 parts of hexamethoxymethylmelamine, 2-4 parts of a static inhibitor, 1-2 parts of rice bran wax, 1-2 parts of lanolin alcohol, 1-2 parts of cetyl alcohol, 0.5-1 part of hydrogenated palm oil, 0.5-1 part of dipentaerythritol, and 0.3-0.5 part of a maleic anhydride grafting compatilizer. On one hand, by adoption of a static electricity eliminating way, the flexibility of a polyester fiber is effectively improved, and the problem of pilling is solved, and on the other hand, the dye-uptake of a dye on the polyester fiber is remarkably improved, and the color fastness of the dye is strengthened.

Description

[0001] Technical field: [0002] The invention relates to the technical field of chemical industry, in particular to a polyester fiber treatment agent prepared by utilizing hydroxyethyl methacrylate. [0003] Background technique: [0004] Hydroxyethyl methacrylate is produced by the reaction of ethylene oxide and methacrylic acid, often referred to as HEMA. Hydroxyethyl methacrylate is a colorless, transparent and easy-flowing liquid, soluble in common organic solvents and miscible with water. Mainly used in the production and modification of resins and coatings, lubricating oil washing additives, fabric adhesives and synthetic medical polymer materials, etc. [0005] Polyester fiber is currently the largest type of synthetic fiber. It has the advantages of good wrinkle resistance and shape retention, high strength and elastic recovery ability, but the biggest disadvantage is that it is easy to pill and fluff and has poor dyeability. In order to improve these shortcomings, p...
