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 sodium hydroxide, and 2kg of calcium persulfate into the reaction tank respectively, carry out 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 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 sodium hydroxide, and 2kg of potassium hydrogen persulfate into the reaction tank respectively, carry out the compound mixing reaction at 38°C for 1.5 hours, then stop 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.

Embodiment 3

[0028] Put 92kg of cornstarch, 6kg of trimethylamine hydrochloride, 1kg of sodium hydroxide, and 1kg of ammonium persulfate into the reaction tank, carry out compound mixing reaction at 38°C for 1.5 hours, then stop 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 slurry. The slurry is formed by commixture reaction of raw materials including corn starch, sodium hydroxide, trimethylamine hydrochloride and persulfate with the following quality content: 80-95% of the corn starch, 1-10% of the sodium hydroxide, 1-15% of the trimethylamine hydrochloride, and 0.1-15% of persulfate. The cation high performance slurry has the advantages of strong adhesive force, good film formation property, tenacious chorion and good elasticity, the flexibility (anti-fatigue property) is improved by 3-4 times compared with common modified starch slurry, the cation high performance slurry has good wear-resisting property and ageing resistance, and a serous fluid has good liquidity and stable viscosity under an I normal temperature condition; and the slurry contains no polyvinyl alcohol, when a spinning purified cotton yarn is subjected to a sizing process, a variety with 60 yarns with common compactness can be processed without polyvinyl alcohol, when sash cotton or purified cotton yarn with more than 60 yarns is subjected to sizing process, little polyvinyl alcohol or no polyvinyl alcohol is used, desizing is easy, waste water of serous fluid is easy to process, pollution of the waste water to the environment is small, and zero-pollution discharge in the production process is realized.

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...
