AI Technical Summary

Problems solved by technology

However, polyester fiber is hydrophobic, and its moisture absorption and perspiration performance is poor. It produces electrostatic effect and makes it easy to be stained. Moisture absorption and perspiration finishing agent came into being
[0003] There are also different types of products on the market, but they have disadvantages such as high cost, poor chemical properties, large foam, poor compatibility, cannot be bathed with polyester dyeing, and are not washable.

preparation example Construction

[0012] The invention discloses a preparation method of a hygroscopic quick-drying finishing agent that is washable and soft to the touch, comprising the following steps:

[0013] (1) Add 15g DMT into a 250mL three-necked flask, heat it to 150-160°C, add 80g PEG and 0.003g catalyst after the DMT is completely melted, continue to heat up to 230-240°C, and carry out the transesterification reaction until the methanol distillate is Until 95-98% of the theoretical value, the transesterification reaction is terminated; the catalyst is chromium oxide.

[0014] (2) Add 155g PEG1500, TPP and 0.003g catalyst, pass nitrogen, and heat up to the polycondensation reaction temperature of 260°C, hold for one hour and then vacuumize, maintain the vacuum degree of 0.1MPa and the temperature of 260°C for the polycondensation reaction. After the reaction for 5 hours, the temperature is lowered. The material is discharged, then cooled and dried, and then pulverized into a block to obtain a hygrosc...

Abstract

The invention discloses a preparation method for a wash-fast and spongy moisture-absorbing quick-dry finishing agent. A product of the finishing agent adopts new raw materials of DMT and PEG, and a catalyst and an anti-oxidant are cooperatively used, cost of the product is greatly reduced, great production cost is saved for follow-up using of a printing and dyeing factory, and processing competitive advantage of the printing and dyeing factory is increased. The product is capable of cutting in cold water, less in foam, high-temperature-resistant, dyeing and co-bathing with dacron, in comply with technical requirements of energy conservation and emission reduction, and capable of reducing a pressure of an enterprise to environmental protection. Washable frequency of the product is up to more than 30 times, a washable problem of sportswear fabric for ordinary household is completely solved, and good hydrophilic and quick-dry functions can be still achieved after 30 times. The product hasgood fluffy and soft hand feeling, and is capable of reducing a dosage of a softening agent in a later stage. In addition, the product does not contain silicon, and is in comply with items of GOTS and ZDHC laws and regulations, and environment-friendly.

Description

technical field [0001] The invention relates to the technology in the field of textile chemicals, in particular to a preparation method of a hygroscopic quick-drying finishing agent that is washable and soft to the touch. Background technique [0002] With the rapid development of the economy in modern society, food problems have infringed people's health to a certain extent, and social survival competition has also brought certain pressure on people's body and mind. Exercise and fitness are particularly important and popular. . Exercise can not only expel physical pain, but also relieve psychological stress. With the improvement of living standards, people's requirements for the comfort of sports fabrics are also increasing. The fabric of sportswear requires good comfort, and also requires that once sweating occurs during activities, the clothing will not stick to the skin and produce a cold and wet feeling, so there is a requirement for moisture absorption and perspira...
