preparation example Construction

[0021] The preparation method of the water-based high anti-velvet finishing agent of the present invention is as follows, first add calcium oxide to 3-4 parts of water, stir evenly, then add water-based polyurethane resin, add organosiloxane to 3-4 parts of water, stir well and then Add the mixture of calcium oxide, water-based polyurethane resin and water that is stirred evenly, and finally add bridging agent and crosslinking agent to the mixed solution in turn, after stirring evenly, add 2-4 parts of water to adjust the viscosity of the mixed solution to 18000cps -23000cps. Adding calcium oxide into water for hydrolysis and then adding water-based polyurethane resin can prevent calcium oxide from being directly added to water-based polyurethane resin with too high viscosity to cause agglomeration, ensure water-resistant performance and reduce drilling wool. Stir the water and organosiloxane evenly first, the purpose is to disperse the organosiloxane evenly in the water-based...

Abstract

The invention aims to solve the problems in the prior art that during fabric after-treatment of a down-proof finishing agent and a down-proof finishing method, the environmental friendliness and the fabric strength are low, the water resistance is poor and the down-proof performance is low, and provides a water-based highly down-proof finishing agent, a preparation method thereof and a down-proof fabric after-treatment method. The water-based highly down-proof finishing agent comprises 60-85 parts of polyurethane resin, 3-13 parts of organosilicone, 5-10 parts of nanoscale calcium oxide, 3-10 parts of water, 3-6 parts of a bridging agent, and 1-2 parts of a cross-linking agent. As water serves as the solvent, no pollution and good environmental friendliness are realized in the treatment process; the water-based polyurethane resin, the organosilicone and the nanoscale calcium oxide serve as main components, so that an integral protecting film is formed on the fabric surface, the weave clearances between fabric warps and wefts can be made up while down feather is prevented from getting out of the fabric surface, and the anti-tearing capability of the fabric cannot be reduced.

Description

technical field [0001] The invention relates to a finishing method of polyester fabric. Background technique [0002] With the advent of the 21st century and the continuous development of social economy, people pay more and more attention to their own safety, especially the environmental protection of clothing. At the same time, people are increasingly pursuing light clothing and getting rid of the shackles of bulky clothing, so lightweight down jacket fabrics have emerged as the times require. Lightweight down jacket fabric refers to the fabric made of 10D-20D yarn. The down jacket made of this lightweight down jacket fabric, including down filling and accessories, has a total weight of less than 200 grams, which is only equivalent to the weight of an apple, so it is very light. , It is very convenient and comfortable to wear. [0003] At present, oily PA resin or PU resin is used to coat the ultra-light down fabric of the present invention. Well-known oily PA resin or P...
