Abstract

Starch textile size is made from, by weight, 10 to 16 parts of acrylic acid, 8 to 22 parts of vinyl acetate, 1 to 4 parts of carboxymethyl cellulose, 6 to 9 parts of maleic anhydride, 12 to 20 parts of methyl acrylate, 8 to 15 parts of polyoxyethylene alkylphenol, 8 to 14 parts of cassava starch, 3 to 5 parts of beta-glucan, 4 to 12 parts of phosphate starch, 5 to 8 parts of guar gum, 10 to 20 parts of modified starch, 4 to 10 parts of polyacrylate emulsion, and 2 to 5 parts of sodium sulfamate. The starch textile size is good in film-forming ability, viscosity stability and gel resistance, sizing cost is lower, desizing is easy, and the starch textile size is pollution free.

Description

A kind of starch textile size

Technical field

The present invention relates to a kind of starch textile size.

Background technology

Sizing is the critical process of weaving engineering, and the object of sizing mainly improves the ABRASION RESISTANCE of yarn, reduces filoplume, suitably increases the brute force of yarn, reduces degree of stretching, and to bear yarn mechanism ability complicated in weaving process, improves the weavability energy of yarn.Mainly use three major types spinning sizing agent both at home and abroad now: starch, polyvinyl alcohol (PVA) and acrylic size three major types, polyvinyl alcohol (PVA) and acrylic size respectively have advantage, but also there is the defect that some are serious, such as polyvinyl alcohol critical defect is the pollution to environment, desized wastewater causes larger environmental pollution, in today that mankind's environmental consciousness is more and more strong, existing country starts to prohibit the use PVA slurry in the world, and PVA slurry can by replacement slowly.The defect of acrylic size is that serous coat is soft, and hygroscopicity, again viscosity are higher, and poor fluidity uses inconvenience, makes it in application, be subject to a definite limitation.It is with a long history that starch is used for warp sizing, because starch is a kind of aftergrowth, aboundresources source is wide, and cheap, have good adhesion property to hydrophilic fibre, therefore in three major types slurry, consumption is maximum.Starch textile size advantage is good film-forming property, and serous coat brute force is high, but serous coat is crisp and hard, and degree of stretching is little, and slurries use viscosity B coefficent comparatively large in a long time, affect sizing quality.Starch environmental protection and energy-conservation in occupy very large advantage, performance needs further improve to improve performance, and then meets the need of market.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of starch textile size, has good film forming, and viscosity stability and anti-gel property, reduce sizing cost, is easy to destarch, and pollution-free.

For solving prior art problem, technical scheme provided by the invention is, a kind of starch textile size, and it is made up of the raw material of following parts by weight:

Acrylic acid 10-16 part, vinylacetate 8-22 part, carboxymethyl cellulose 1-4 part, maleic anhydride 6-9 part, methyl acrylate 12-20 part, polyoxyethylene alkylphenol 8-15 part, tapioca 8-14 part, β-glucan 3-5 part, phosphate ester starch 4-12 part, guar gum 5-8 part, converted starch 10-20 part, polyacrylate dispersion 4-10 part, sulfamic acid sodium 2-5 part.

The invention has the beneficial effects as follows: starch textile size of the present invention, have good film forming, viscosity stability and anti-gel property, reduce sizing cost, is easy to destarch, and pollution-free.
