Problems solved by technology

[0002] Nylon and nylon / spandex fabrics are often used as sports and leisure fabrics and women's underwear fabrics. They are soft to the touch, comfortable to wear, breathable and elastic, etc. However, as people's sports and leisure fabrics and underwear fabrics become more and more demanding Its own performance cannot meet the higher demand of people for clothing. Nylon, nylon / spandex sports and leisure and underwear fabrics not only require soft, plump and elastic but also good hydrophilic properties. The improvement of these wearing properties needs to be passed. The method of finishing is achieved by adding some finishing agents
[0003] The use of similar finishing agents is seen in the prior art, but the hydrophilic performance and hand feeling of existing similar finishing agents on nylon, nylon / spandex knitted fabrics still cannot meet the requirements of high-end products, and similar The washability of the finishing agent on the fabric is not good, and it is necessary to add a crosslinking agent to improve the washability of the finishing agent on the fabric. There is no public report on the related technology involved in the present invention.

Embodiment 1

[0028] The reaction kettle is dried to remove water, and 300Kg EO / PO block polyether glycol (molecular weight: 1950) is injected. The temperature is slowly raised to 120°C to remove water under reduced pressure for 2h, and the temperature is reduced to 30-40°C. Slowly add 41Kg diisocyanate IPDI, and increase the temperature. After reacting at 80℃ for 2h, slowly add 7.1Kg of capping agent methyl isobutyl ketoxime and react at 80~85℃ for 4h, cooling to obtain a colorless and transparent capped thermally reactive polyurethane prepolymer, and cooling to 40 Add 200Kg of diethylene glycol monobutyl ether, 150Kg of stearic acid polyoxyethylene ether (9EO), 301.9Kg of deionized water at ℃, and stir to get it.

Embodiment 2

[0030] The reaction kettle is dried to remove water, and 300Kg EO / PO block polyether glycol (molecular weight: 1950) is injected. The temperature is slowly raised to 120°C to remove water under reduced pressure for 1h, and the temperature is reduced to 30-40°C. 46.2Kg of diphenylmethane is slowly added Diisocyanate MDI, heated to 80℃ and reacted for 2h, slowly added 2.7Kg of blocking agent methyl ethyl ketoxime, reacted at 80~85℃ for 4h, cooled to obtain a colorless and transparent blocked thermoreactive polyurethane prepolymer, and cooled to 40 Add 200Kg of diethylene glycol monobutyl ether, 100Kg of polyether hydrophilic silicone oil, and 351.1Kg of deionized water at ℃, and stir to get it.

Embodiment 3

[0032] The reaction kettle is dried and dewatered, and 300Kg EO / PO block polyether glycol (molecular weight 1950) is injected. The temperature is slowly raised to 120°C to remove water under reduced pressure for 2h, and the temperature is lowered to 30-40°C. 31Kg diisocyanate HDI is slowly added, and the temperature is raised After reacting at 80℃ for 2h, slowly add 7.0Kg of end-capping agent cyclohexanone oxime, react at 85℃ for 4h, and cool to obtain a colorless and transparent end-capped thermoreactive polyurethane prepolymer. When the temperature is lowered to 40℃, add 200Kg Glycol monobutyl ether, stearic acid polyoxyethylene ether (9EO) 150Kg, deionized water 312Kg, stir well to get.

Abstract

The invention discloses a preparation method and application of a moisture-absorbing sweat-releasing quick-drying finishing agent applied to nylon or nylon / spandex fabric. The method comprises: taking diisocyanate, EO / PO block polyether glycol and an end-capping reagent ketoxime as raw materials to prepare colorless transparent end-capped heat-reactive polyurethane prepolymer, compounding with stearic polyoxyethylene ether or hydrophilic silicone oil, and adding diethlyeneglycol monobutylether as a solvent and water to prepare the finishing agent. The developed finishing agent helps finished nylon or nylon / spandex fabric to have the soft, full, smooth and good-drapability handfeel, and the finished fabric has excellent hydrophilic performance and moisture absorption performance and is applicable to leisure sportswear fabric, woman underwear fabric and the like, so that the added value of products is improved. The developed moisture-absorbing sweat-releasing quick-drying finishing agent applied to nylon or nylon / spandex fabric does not need an additional cross-linking agent when used, and has extremely good washing resistant performance after applied to fabric.

Description

【Technical Field】 [0001] The invention relates to a preparation method and application of a moisture wicking and quick-drying finishing agent, in particular to a preparation method and application of a moisture wicking and quick-drying finishing agent for nylon or nylon / spandex fabrics. It belongs to the technical field of textile chemical industry. 【Background technique】 [0002] Nylon, nylon / spandex fabrics are often used as sports and leisure fabrics and women's underwear fabrics. They have soft hand feeling, comfortable wearing, good breathability and elasticity. However, as people's sports and leisure fabrics and underwear fabrics have higher and higher requirements, these fabrics The performance itself is not enough for people's higher demand for clothing. Nylon, nylon / spandex sports leisure and underwear fabrics not only require soft hand feeling, fullness and elasticity, but also require good hydrophilic properties. The improvement of these wearing properties needs to be ...
