preparation example Construction

[0035] The embodiment of the present invention provides a method for preparing a cooling hydrogel, comprising the following steps:

[0036] A) under the effect of dispersant, peppermint oil and xylitol are mixed with water to obtain mixed solution;

[0037] B) mixing the mixed solution with N-vinylpyrrolidone, acrylamide, an initiator, a crosslinking agent and water, and performing in-situ free radical polymerization to obtain a cool-feeling hydrogel.

[0038] The invention adopts a coating process to prepare the cooling-feeling hydrogel, and the process flow mainly includes emulsification, polymerization, etc., and the method is simple and easy.

[0039] In the embodiment of the present invention, peppermint oil, xylitol, dispersant and water are mixed, preferably under the condition of stirring, to obtain a mixed solution by emulsification.

[0040]The present invention mainly uses peppermint oil and xylitol as ice-feeling raw materials, and the contents of the peppermint o...

Abstract

The present invention discloses a cool feeling hydrogel, which is a peppermint oil and xylitol wrapped acrylamide / N-vinylpyrrolidone copolymer hydrogel. The hydrogel uses the peppermint oil and xylitol icy feeling combination to bring the human body super strong icy cool feeling, and the icy cool feeling effect had good durability. Meanwhile, a textile fabric prepared from the hydrogel is always in a point contact with human body to ensure that textiles may not be pasted on the skin due to increase of the amount of sweat, and the hydrogel is used, to be equivalent, the inner layer of the textile is additionally provided with boss holes, an air layer may be exist in the boss holes, when the textile inner space is large, stack effect is easy to produce, the body heat loss is greatly increased, the body temperature is reduced, textile ventilation and breathability perspiration properties can be improved, and the textile microclimate comfort property can be improved. The present invention also provides a preparation method of the cool feeling hydrogel, and a cool feeling fabric and a preparation method of the cool feeling fabric.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a cooling hydrogel and a preparation method thereof, a cooling fabric and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's requirements for quality of life, functional textile fabrics have attracted more and more attention. Cool fabrics are functional textile fabrics, which can quickly diffuse body heat, accelerate sweat dissipation and lower body temperature after the human body touches the fabrics. It can provide people with a comfortable and cool quality of life. [0003] Most of the cooling fabrics currently on the market are processed in the following two ways: one is to use ice-feeling additives, which are realized by finishing and padding. The disadvantage of this method is that the durability of the ice-feeling effect is poor. The other is to use ice-fe...
