Method for improving sizing adhesive formula by means of ammonium dihydrogen phosphate and silane coupling agent

Abstract

The invention relates to a method for improving a sizing adhesive formula by means of ammonium dihydrogen phosphate and a silane coupling agent, and belongs to the field of textile processing. The method comprises the step of adding the ammonium dihydrogen phosphate and the silane coupling agent to the sizing adhesive formula containing phosphate ester starch, acrylic ester and water, wherein the mass of the phosphate ester starch is 3%-5% of the total mass of the sizing adhesive formula, the mass of the acrylic ester is 3%-5% of the total mass of the sizing adhesive formula, the mass of the ammonium dihydrogen phosphate is 0.1%-1% of the total mass of the sizing adhesive formula, and the mass of the silane coupling agent is 0.1%-2% of the total mass of the sizing adhesive formula. Due to the fact that the ammonium dihydrogen phosphate and the silane coupling agent are added into an adhesive, containing the phosphate ester starch and solid acrylic ester, for mixed sizing, the permeability of the adhesive for mixed sizing and the coating property of the adhesive for yarn surface sizing can be significantly improved, and the sizing membrane property is enhanced.

Description

technical field [0001] The invention relates to a method for improving the formula of an adhesive for sizing by using ammonium dihydrogen phosphate and a silane coupling agent, and belongs to the technical field of textile processing. Background technique [0002] During weaving, the effect of the warp yarn on the heald frame will produce about 4000 reciprocating motions during the process from the warp beam to the fell. In this process, the role of the binder that protects the performance of the warp yarn is to increase the strength and reduce hairiness. The three types of adhesives commonly used in the textile processing industry are: starch, acrylic and polyvinyl alcohol. The properties of the binder play an important role in the properties of the warp after padding the binder. Therefore, in order to protect the warp yarn, the warp yarn is padded with adhesive. The adhesive protects the warp yarn mainly from two aspects: one is that the adhesive penetrates into the yarn...

Such as the Chinese publication "Macromolecular Materials Science and Engineering", the publication date is August 2009, the title of the article is the texture structure and performance of the phosphate starch / polyacrylate blend film. Supplemented with polyacrylate size to improve the flexibility of the size film, the disadvantage is that only phosphate starch supplemented with acrylic polyacrylate to improve the flexibility of the size film still cannot meet the requirements of the warp yarn during weaving. The requirements of surface size film flexibility, such as the Chinese publication "Cotton Textile Technology", the date of publication in November 2010, the title of the article is the study of maleic anhydride esterified acrylate grafted starch size, and this document introduces a The method of utilizing maleic anhydride to esterify acrylate grafted starch to improve the flexibility of the size film has the disadvantages that the starch grafting process is long, time-consuming, and energy-consuming, such as Chinese Patent Publication No. CN102329437A, disclosed On January 25, 2012, the name of the invention was a degradable starch composite slurry. The application disclosed a slurry compounded with plant starch, acetylated distarch phosphate, polyacrylic acid, starch and PVA. The disadvantage is that although the toughness of the size film is increased, the PVA cannot be degraded quickly after desizing and pollutes the environment.

Such as China's public publication "Cotton Textile Technology", the publication date was July 2012, and the title of the article is the modification of water-based polyurethane to starch size. This document has explained that adding water-based polyurethane components to starch size can make adhesion Improve the strength of the size film and improve the mechanical properties of the size film. The disadvantage is that the improvement of the performance of the size film by adding water-based polyurethane still cannot meet the conditions of warp sizing.
