Problems solved by technology

Starch size has good film-forming properties, strong affinity with natural fibers, and is easy to desizing; but starch size sizing is not strong enough, easy to break, and poor wear resistance
Polyvinyl alcohol size film has strong strength and good flexibility, and is often used for sizing pure cotton, but it is difficult to desizing polyvinyl alcohol, and the desizing wastewater is not easy to degrade, causing great environmental pollution
Polyacrylic acid slurry has low viscosity, good fluidity, and good adhesion to synthetic fibers. In actual production, it can be mixed with starch and polyvinyl alcohol slurry, but the price of polyacrylic acid slurry has always been high. Conducive to textile enterprises to reduce production costs

Embodiment 1

[0012] An environmentally friendly slurry for pure cotton yarn is made from the following raw materials in mass ratio: 50% of dried distiller's grain powder, 25% of sodium hydroxide solution, 10% of triethanolamine, 5% of epichlorohydrin, and 10% of butyl acrylate. Among them, dry distiller's grains is a by-product of the beer industry, which is the residue after fermenting and extracting soluble carbohydrates in the seeds with barley as raw material.

Embodiment 2

[0014] An environmentally friendly slurry for pure cotton yarn is made from the following mass ratio raw materials: 65% of dried distiller's grain powder, 20% of sodium hydroxide solution, 5% of triethanolamine, 5% of epichlorohydrin, and 5% of butyl acrylate. Among them, dry distiller's grains is a by-product of the beer industry, which is the residue after fermenting and extracting soluble carbohydrates in the seeds with barley as raw material.

Embodiment 3

[0016] An environmentally friendly slurry for pure cotton yarn is made from the following mass ratio raw materials: 75% of dried distiller's grain powder, 5% of sodium hydroxide solution, 6% of triethanolamine, 8% of epichlorohydrin, and 6% of butyl acrylate. Among them, dry distiller's grains is a by-product of the beer industry, which is the residue after fermenting and extracting soluble carbohydrates in the seeds with barley as raw material.

Abstract

The invention discloses an environmentally friendly slurry for pure cotton yarn, which is made of the following mass ratio raw materials: 50-75% of dried distiller's grain powder, 5-25% of sodium hydroxide solution, 2-10% of triethanolamine, epoxy chlorine Propane 3-8%, butyl acrylate 1-10%. The invention adopts powdered beer dried distiller's grains powder as a raw material for preparing composite slurry, not only effectively utilizes waste protein resources, but also shortens extraction time, improves yarn strength and reduces yarn hairiness.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an environmentally friendly size for pure cotton yarn. Background technique [0002] The purpose of sizing is to saturate and cover the yarn with sizing material to increase its strength, improve wear resistance, and reduce hairiness, thereby reducing or preventing warp yarn breakage in the weaving process and improving weaving efficiency. It is a must in the textile industry. An indispensable process. At present, the three main varieties in the size industry are: polyvinyl alcohol, modified starch and acrylic size. Starch size has good film-forming properties, strong affinity with natural fibers, and is easy to desizing; but starch size has insufficient sizing strength, is easy to break, and has poor wear resistance. Polyvinyl alcohol sizing film has high strength and good flexibility, and is often used for sizing pure cotton. However, it is difficult to desizing polyvinyl al...
