Embodiment Construction

[0007] Take 1.5 parts of a-amylase plant starch, 50 parts of acetylated distarch phosphate, 30 parts of polyacrylic acid, 40 parts of starch slurry, 5 parts of PVA slurry, and 3 parts of wax flakes, and prepare a total amount of 750L. It is 16Pa.S.

[0008] The comparative test of the sizing results is as follows;

[0009] Serosa breaking strength: 31N.m;

[0010] Abrasion: 15mg / mm;

[0011] Adhesion: 68N;

[0012] Sizing rate of sizing: 8.5%;

[0013] Slurry permeability: 38%;

[0014] Serosa integrity rate: 70%.

[0015] The degradable starch composite size greatly reduces the environmental pollution of the original size, has excellent adhesion and film-forming properties, and the size film is flexible, wear-resistant, smooth, elastic, and easy to degrade. Polyester, hemp, viscose, silk and other fibers have very good results.

Abstract

The invention relates to a degradable starch composite size which mainly comprises the following components in parts by weight: 1-2 parts of alpha-amylase plant starch, 45-55 parts of acetylated distarch phosphate, 10-40 parts of polyacrylic acid, 35-45 parts of stearic polyoxyethylene ester, 5-10 parts of PVA (polyvinyl acetate) size, 1-3 parts of wax slice and the like. By using the degradable starch composite size, the pollution of the original size on environment can be greatly reduced; the degradable starch composite size has good adhesive power and film forming ability, and a size film is flexible, wear-resisting and slippery, has high resilience, is easy to degrade and has good effects on fibers such as cotton, polyester, flax, viscose, silk and the like.

Description

technical field [0001] The invention relates to a degradable starch composite slurry, which is a starch material for making fragrance, and belongs to the technical field of composite modified starch. Background technique [0002] In warp sizing in the domestic textile industry, modified starch has been used for more than 20 years. Although modified starch manufacturers and scientific research units have made a lot of efforts to develop many varieties of modified starch, modified starch can only play a role. Partially replace the role of PVA, and cannot become the main slurry or the main component of the slurry. [0003] PVA sizing is called "unclean sizing" because it is resistant to acid, alkali, and microorganisms and is difficult to degrade in nature. European countries and other countries have set environmental protection restrictions and strictly prohibit the use of PVA sizing in textile production. However, since denim is a medium-coarse and high-density product, it r...
