Embodiment 1

[0025] Put 70kg of corn starch, 17kg of creatine phosphate sodium, 8kg of phosphorus oxychloride, 3kg of Tween, and 2kg of calcium persulfate into the reaction tank respectively, carry out compound mixing reaction at room temperature for 1 hour, terminate the reaction, unload and pack, and store . When the customer is using it, add water to gelatinize and heat up to 95°C or add water in a high-pressure tank to heat up to 120°C and keep it warm for 15-30 minutes to carry out oxidation, cross-linking, esterification, emulsification, and polymerization to prepare the emulsion.

[0026] The mass ratio of clear water to multi-component high-performance slurry is 82:18.

Embodiment 2

[0028] Put 80kg of cornstarch, 12kg of diammonium phosphate, 5kg of chloroxypropane, 2kg of Tween, and 1kg of potassium hydrogen persulfate into the reaction tank respectively, carry out compound mixing reaction at room temperature for 2 hours, then terminate the reaction, unload and pack, and store . When the customer uses it, add clear water to gelatinize and heat up to 95°C or add clear water in a pressure cooker to heat up to 120°C and keep warm for 15-30 minutes to carry out oxidation, cross-linking, esterification, emulsification, and polymerization to obtain an emulsion.

[0029] The mass ratio of clear water to multi-component high-performance slurry is 85:15.

Embodiment 3

[0031] Put 90kg of cornstarch, 5kg of potassium dihydrogen phosphate, 2kg of phosphorus oxychloride, 2kg of Tween, and 1kg of ammonium persulfate into the reaction tank respectively, carry out compound mixing reaction at room temperature for 3 hours, then terminate the reaction, unload and pack, and store . When the customer is using it, add water to gelatinize and heat up to 95°C or add water in a high-pressure tank to heat up to 120°C and keep it warm for 15-30 minutes to carry out oxidation, cross-linking, esterification, emulsification, and polymerization to prepare the emulsion.

[0032] The mass ratio of clear water to multi-component high-performance slurry is 88:12.

[0033] Specific implementation of the product application program:

[0034] 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...

Abstract

The invention discloses a multi-component high-performance sizing agent. The sizing agent is prepared from various raw materials by a mixing reaction, wherein the raw materials comprise corn starch, phosphate, tween, persulfate, and at least one of phosphorus oxychloride and epoxy chloropropane. The sizing agent has the characteristics that the adhesion force is high, the film-forming ability is high, a serous film is coriaceous, the elasticity is high, the bending resistance (fatigue resistance) is improved by 3 to 4 times compared with a common modified starch sizing agent, and the abrasion resistance and the ageing resistance are high. The serous liquid is not frozen, caked or layered at normal temperature, and has high liquidity and stable viscosity. The sizing agent has no polyvinyl alcohol; when the sizing agent is sized on spinning cotton yarns; for the variety with general tightness, the polyvinyl alcohol does not need to be used for less than 50 yarns; or no or less polyvinyl alcohol is used for sizing on polyester cotton or over 50 cotton yarns; the yarns are easy to desize; the serous liquid waste water is easy to treat; the environment pollution is low; and the production process has zero pollution emissions.

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, because the price of polyvinyl alcohol (PVA) size is much higher than that of starch-based size, in addition to polyvinyl alcohol (PVA) size and some refractory size, the slurry wastewater after desizing is difficult to treat, causing environmental pollution. Pollution. The damage to the environment and the pollution problem have attracted widespread attention, especially the fabrics sized with polyvinyl alcohol (PVA) sizing ...
