Abstract

The invention discloses a polyester cotton sizing aid and a preparation method thereof. The polyester cotton sizing aid comprises the following raw materials in percentage by weight: 10.00-15.00 wt% of ethylene glycol, 3.00-8.00 wt% of polyethylene glycol (PEG), 1.50-3.00 wt% of sorbitan fatty acid ester polyoxyethylene ether, 1.50-3.00 wt% of fatty alcohol-polyoxyethylene ether, 0.80-2.50 wt% of antistatic agent, 3.0-7.0 wt% of degreasing agent, 0.05-0.3 wt% of defoamer, 0.1-0.5 wt% of preservative and the balance of water. The preparation method comprises the following steps: sequentially adding the ethylene glycol, polyethylene glycol (PEG), sorbitan fatty acid ester polyoxyethylene ether, fatty alcohol-polyoxyethylene ether, the antistatic agent and the degreasing agent into water which is being stirred; heating and fully stirring; adjusting the pH value to be neutral; and adding the defoamer and the preservative. The cost is lower, the adhesive force of the sizing agent is stronger, the viscosity of the sizing agent is stable, and a sizing film is flexible and excellent in performance.

Description

Technical field[0001]The present invention relates to the field of textile depassing, and more particularly to a polyester coil aid and a method of preparation.Background technique[0002]At present, PVA, starch, polyacrylic acid is three large slurrys on the slurry. During the surface of natural fibers such as cotton, since the fiber structure is rich in a large amount of hydroxyl group, similarity to the slurry structure such as starch, acrylic, auxiliary agent, is easy to form hydrogen bonds and better compatibility. It greatly enhances the affinity and adhesion between fibers and slurry, which has completely realized no PVA overlooking, or even low cost without PVA depassry.[0003]However, in the polyester, PVA is still the best choice of the upper paste material, which brings severe challenges and pressure to the downstream printing and dyeing enterprises. At the same time, my country's polyester and polyester blend products have ranked first in the world. Exports to foreign count...
