Problems solved by technology

[0002] During the production, processing and finishing of polyester-cotton fabrics, there will be more fluff on the surface of the fabric, coupled with electrostatic reaction, after wearing for a period of time, the surface of the fabric is prone to pilling, which affects the appearance and comfort. At present, fabric anti-pilling finishing The main problem of the agent is low economic benefit, poor stability, high cost, long processing time, and some processes will affect the color and strength of the handle. Therefore, the quality of the anti-pilling finishing agent needs to be improved

Abstract

The invention discloses an anti-pilling finishing agent for polyester cotton garment fabric and a preparing method thereof. The anti-pilling finishing agent is prepared from, by weight, 30-35 parts of polyester polyhydric alcohol, 20-25 parts of isophorone diisocyanate, 10-15 parts of organic tin, 16-19 parts of dihydroxy methyl propionate, 5-8 parts of N-methyl pyrrolidone, 12-15 parts of sodium hydrogen sulfite, 11-14 parts of carboxylic acid, 13-17 parts of triethylamine and 30-35 parts of deionized water. The preparing method includes the steps that polyester polyhydric alcohol is heated, dehydrated in vacuum and naturally cooled to 20 DEG C-25 DEG C, isophorone diisocyanate and organic tin are added and react with the polyester polyhydric alcohol for 1.5-2.5 h at the temperature of 60 DEG C-70 DEG C, then a solution prepared by mixing dihydroxy methyl propionate and N-methyl pyrrolidone for 5-10 min is added, and a polyurethane prepolymer containing carboxyl hydrophilic groups are prepared after reaction is conducted for 20-40 min. The anti-pilling finishing agent has an excellent anti-pilling function, the preparing process is simple, easy to operate and low in cost, a chemical method is used in the finishing process, the garment fabric is stable in performance after being treated, the treatment effect is good, the operation of finishing the garment fabric is simple, and finishing time is short.
