Problems solved by technology

The advantages of starch textile size are good film-forming properties and high strength of the size film, but the size is brittle and hard, and the elongation is small. The viscosity of the size changes greatly after a long period of time, which affects the sizing quality.

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

technical field [0001] The present invention relates to an improved starch textile size. Background technique [0002] At present, three major categories of textile size are mainly used at home and abroad: starch, polyvinyl alcohol (PVA) and acrylic size. Polyvinyl alcohol (PVA) and acrylic size have their own advantages, but there are also some Serious defects, such as the fatal defect of polyvinyl alcohol is the pollution of the environment, the desizing wastewater causes greater environmental pollution, and today, with the increasing awareness of human environmental protection, countries in the world have begun to ban the use of PVA slurry, PVA The slurry will be slowly replaced. The disadvantages of acrylic size are soft size film, high hygroscopicity and re-viscosity, poor fluidity and inconvenient use, which limit its application. Starch has a long history of being used in warp yarn sizing, because starch is a regenerated plant with abundant resources, low price, and...
