Environment-friendly spinning size and preparation method thereof

Abstract

The invention provides environment-friendly spinning size and a preparation method thereof. The environment-friendly spinning size comprises native starch, polyester, polyacrylate, refined salt, urea, peregal O, phosphate, borax and viscosity reducer. The preparation method includes: stirring and mixing raw materials except for the native starch, adding the native starch, and mixing and stirring well to obtain the environment-friendly spinning size. The spinning size is simple in size mixing, high in stability and permeability and suitable for various yarns, and the preparation method is simple, low in cost and good in application prospect.

Description

technical field [0001] The invention relates to the technical field of textile sizing, in particular to an environment-friendly textile size and a preparation method thereof. Background technique [0002] In the textile industry, the currently commonly used textile size mainly includes: starch size, PVA and acrylic size. [0003] As the earliest used textile size, starch size has the advantages of easy acquisition of raw materials and low price. However, starch size has obvious disadvantages, such as poor fluidity, unstable viscosity, poor adhesion to synthetic fibers, and hard and thick size film. crisp. [0004] PVA size has strong adhesion to fibers, good wear resistance of size film, good miscibility, excellent sizing effect, but poor yarn separation, secondary hairiness, difficult to desizing, difficult to degrade, easy to cause environmental pollution, Using less or not using PVA is an inevitable trend in the development of slurry. [0005] Acrylic size also has goo...

Problems solved by technology

[0003] As the earliest used textile size, starch size has the advantages of easy acquisition of raw materials and low price. However, starch size has obvious disadvantages, such as poor fluidity, unstable viscosity, poor adhesion to synthetic fibers, and hard and thick size film. crisp

[0004] PVA size has strong adhesion to fibers, good wear resistance of size film, good miscibility, excellent sizing effect, but poor yarn separation, secondary hairiness, difficult to desizing, difficult to degrade, easy to cause environmental pollution, Using less or not using PVA is an inevitable trend in the development of slurry

[0005] Acrylic size also has good size film strength, good penetrability, and easy desizing after several times of replacement, and there are many varieties of acrylic size with different characteristics. However, acrylic size has moisture absorption and stickiness. Sticky, and the preparation process of acrylic slurry is complex and costly
