Problems solved by technology

However, since the price of polyvinyl alcohol (PVA) sizing is much higher than that of starch sizing, coupled with polyvinyl alcohol (PVA) sizing and some refractory sizing, it is difficult to treat the sizing wastewater after desizing, causing environmental pollution. Pollution

Embodiment 1

[0024] Put 85kg of cornstarch, 10kg of trimethylamine hydrochloride, 3kg of calcium hydroxide, and 2kg of calcium persulfate into the reaction tank respectively, carry out the compound mixing reaction at 38°C for 1.5h, then terminate the reaction, unload the package, and put it into storage . When the customer is using it, add clear water to gelatinize and heat up to 95°C or add clear water in a high-pressure tank to heat up to 125°C and keep warm for 30-45 minutes to carry out etherification and oxidation compound reactions to obtain an emulsion for sizing fabrics.

Embodiment 2

[0026] Put 88kg of cornstarch, 8kg of trimethylamine hydrochloride, 2kg of calcium hydroxide, and 2kg of potassium hydrogen persulfate into the reaction tank respectively, carry out the compound mixing reaction at 38°C for 1.5h, and then terminate the reaction. library. When the customer is using it, add clear water to gelatinize and heat up to 95°C or add clear water in a high-pressure tank to heat up to 125°C and keep it warm for 30-45 minutes to carry out etherification and oxidation compound reactions to obtain a fabric sizing emulsion.

Embodiment 3

[0028] Put 92kg of cornstarch, 6kg of trimethylamine hydrochloride, 1kg of magnesium hydroxide, and 1kg of ammonium persulfate into the reaction tank respectively, carry out the compound mixing reaction at 38°C for 1.5h, then terminate the reaction, unload and pack, and store . When the customer is using it, add clear water to gelatinize and heat up to 95°C or add clear water in a high-pressure tank to heat up to 125°C and keep it warm for 30-45 minutes to carry out etherification and oxidation compound reactions to obtain a fabric sizing emulsion.

[0029] All or part of the emulsion size obtained in the above examples is used to replace the polyvinyl alcohol, high-performance starch and ordinary starch in the existing size formula, and the fabric is sized in actual production, and the existing formula is used for comparative experiments . The formulations and production conditions of each group are shown in the table below.

Abstract

The invention discloses cation high-performance size which is made from the following raw materials: corn starch, hydroxides, trimethylamine hydrochloride and persulfate through a hybrid reaction, wherein corn starch accounts for 80%-95% by weight, calcium hydroxide and / or magnesium hydroxide account(s) for 1%-10% by weight, trimethylamine hydrochloride accounts for 1%-15% by weight, and persulfate accounts for 0.1%-15% by weight. The cation high-performance size has the advantages of strong adhesive ability, good film forming property, tough size film, and excellent elasticity; the flexibility (fatigue endurance) is improved by 3-4 times in comparison with common modified starch size; the cation high-performance size is excellent in wear-resisting and anti-aging properties; and the size has good flowability under the condition of normal temperature, and is stable in viscosity. Polyvinyl alcohol is not used. When pure cotton yarns are sized during spinning, 60-count yarns of common tightness do not need polyvinyl alcohol, and when polyester or pure cotton yarns higher than 60-count are sized, no polyvinyl alcohol is needed or only a small amount of polyvinyl alcohol is needed, so that desizing is easy, the size waste is easy to process and causes small pollution to the environment; and zero pollution emission is realized in a production process.

Description

technical field [0001] The invention belongs to the field of textile industry, and in particular relates to a size in the yarn sizing process of the textile industry. Background technique [0002] In the yarn sizing process in the textile industry, because polyvinyl alcohol (PVA) size has excellent film-forming properties, adhesion and better compatibility with other sizes, it is considered to solve the problem of polyester-cotton blending. The most ideal size for spinning and pure cotton fine size, high density and high difficulty varieties. However, since the price of polyvinyl alcohol (PVA) sizing is much higher than that of starch sizing, coupled with polyvinyl alcohol (PVA) sizing and some refractory sizing, it is difficult to treat the sizing wastewater after desizing, causing environmental pollution. pollute. The damage to the environment and pollution problems have attracted widespread attention, especially the fabrics sized with polyvinyl alcohol (PVA) sizing have...
