Method for improving formula of binding agent for sizing by using ethylene glycol phenyl ether

Abstract

The invention relates to a method for improving a formula of a binding agent for sizing by using ethylene glycol phenyl ether and belongs to the field of textile processing. The method comprises the following steps: adding ethylene glycol phenyl ether to the formula of the binding agent for sizing, which contains phosphate starch, acrylate and water, wherein the mass of the phosphate starch accounts for 3-5% of the total mass of the phosphate starch, the acrylate, the ethylene glycol phenyl ether and the water; the mass of the acrylate accounts for 3-5% of the total mass of the phosphate starch, the acrylate, the ethylene glycol phenyl ether and the water; and the mass of the ethylene glycol phenyl ether accounts for 0.1-2% of the total mass of the phosphate starch, the acrylate, the ethylene glycol phenyl ether and the water. According to the binding agent for mixed sizing of the phosphate starch and solid acrylate, the ethylene glycol phenyl ether is added, and the permeability of the binding agent for mixed sizing and the coverage of the binding agent for sizing on surfaces of yarns can be obviously improved, so that the starching effect is improved.

Description

technical field [0001] The invention relates to a method for improving the formula of an adhesive for sizing by using ethylene glycol phenyl ether, which 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, increases the cohesion be...

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.
