Degradable starch composite size

[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.
