Abstract

The invention provides an improved starch textile sizing agent. The improved starch textile sizing agent is prepared from the following raw materials in parts by weight: 8-17 parts of ethylhexyl-2-acrylate, 9-13 parts of dibutyl diacrylate, 10-15 parts of diallyl phthalate, 5-8 parts of hydroxypropyl methylcellulose, 4-7 parts of nano-silicon nitride, 6-8 parts of hydroxypropyl distarch phosphate, 4-9 parts of lauryl alcohol polyoxyethylene, 7-10 parts of polyacrylate, 15-26 parts of modified starch, 18-27 parts of polyvinyl alcohol, 20-26 parts of nano-silicon dioxide modified starch, 8-14 parts of protein size, 3-5 parts of kaolin, 6-15 parts of wheat starch and 2-3 parts of polyacrylate. The improved starch textile sizing agent has the beneficial effects that the sizing yarn quality is improved, the sizing agent high in strength and low in tension is easy to desize, the adhesiveness of the sizing agent is improved, and the sizing yarn quality is improved; besides, the improved starch textile sizing agent is quick to biodegrade and small in environmental pollution.

Description

A kind of starch textile size of improvement

Technical field

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

Background technology

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, utilize starch conversion, performance need further improve to improve performance, and then meet 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 of improvement, improve the slurry of the high-strength flatness of sizing quality, be easy to destarch, improve slurry adhesive performance, improve sizing quality, and biodegradation is fast, environmental pollution is little.

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

Acrylic acid-2-ethyl caproite 8-17 part, two acrylic acid fourth diester 9-13 part, diallyl phthalate 10-15 part, hydroxypropyl methylcellulose 5-8 part, nano-silicon nitride 4-7 part, hydroxypropyl PASELLI EASYGEL 6-8 part, ethoxylated dodecyl alcohol 4-9 part, polyacrylate 7-10 part, converted starch 15-26 part, polyvinyl alcohol 18-27 part, nano SiO 2 modified starch 20-26 part, albumen slurry 8-14 part, kaolin 3-5 part, wheaten starch 6-15 part, polyacrylate 2-3 part.

The invention has the beneficial effects as follows: the starch textile size of improvement of the present invention, improve the slurry of the high-strength flatness of sizing quality, be easy to destarch, improve slurry adhesive performance, improve sizing quality, and biodegradation is fast, environmental pollution is little.
