Pilling resistant agent emulsion for wool fabrics and preparation method thereof

Abstract

The invention discloses pilling resistant agent emulsion for wool fabrics and a preparation method thereof. The emulsion comprises the following raw materials in percentage by weight: 2-8 percent of ethyl hexyl acrylate monomer, 6-16 percent of butyl acrylate monomer, 2-8percent of hydroxyl ester acrylate monomer, 0.1-1.5 percent of anionic surfactant, 0.1-1.5 percent of non-ionic emulsifier, 0.01-0.1 percent of initiator, 0.8-5 percent of siloxane monomer, 5-15 percent of vinyl-contained silane coupling agent, 0.1-1 percent of silane hydrolysis inhibitor and 50-70 percent of de-ionized water; and the emulsion is prepared by adopting the semi-continuous seed emulsion polymerization technique. The pilling resistant agent emulsion has the characteristics of small particle size, low emulsion dosage, easy control of reaction process, no environmental pollution and the like. The pilling resistant grade of the wool fabrics which are treated by the pilling resistant agent emulsion is improved by more than 2 grades; the hydrophily is basically not changed; and the original hand feel and style of the fabrics are little influenced.

Description

technical field [0001] The invention belongs to the field of textile auxiliaries, and relates to an anti-pilling agent emulsion for woolen fabrics and a preparation method thereof. technical background [0002] During the wearing process of woolen fabrics, due to the fabric itself and various external forces and external frictions, it is easy to produce pilling before obvious damage occurs. Pilling on the surface of the fabric generally occurs on natural fiber and chemical fiber fabrics, especially when wool-polyester and wool-acrylic blended fabrics are used as outerwear. Fabric pilling affects the appearance of clothing and reduces wearing performance. With the improvement of living standards, people have higher and higher requirements for the appearance and wearing performance of fabrics. Therefore, anti-pilling finishing of fabrics to improve the wearing comfort and quality of fabrics has become increasingly popular among domestic and foreign dyeing and finishing worker...

Problems solved by technology

However, the problem is that the anti-pilling agent forms a layer of interpenetrating network structure of silicone block acrylate resin on the surface of the fabric to produce anti-pilling effect, while branched chain sulfonic acid, dodecyl Benzenesulfonic acid, persulfate, sulfite, etc. are easy to remain on the surface of the fabric, which will have a negative impact on the service life of the fabric and will hurt human skin

[0006] In order to solve the deficiencies in the prior art, this research group has done more in-depth research on the anti-pilling finishing of woolen fabrics for many years, adopted a variety of methods, and also published a related paper "Preparation of Anti-pilling Agent for Wool Fabrics" and Application Research" (see: "Wool Spinning Science and Technology" 2006 Issue 09 Authors: Ye Mei, Xu Yan, Xie Hongde, etc.), this article preliminarily discussed the use of vinyl-containing silane coupling agents and acrylates for block copolymerization as an anti- Pilling agent is used for finishing, which provides a reference for subsequent anti-pilling finishing research and actual production, but the paper does not mention the relevant ratio, and the polymerization method used is block copolymerization
