Problems solved by technology

In summer, when the sun shines strongly, people will sweat a lot outdoors due to the high ambient temperature. The sweat will soak through the clothing fabric and adhere to the surface of the skin. The air permeability is poor, which greatly affects the thermal physiological comfort of the human body.

Abstract

The invention provides a preparation method of hydrogel cooling cloth. The preparation method comprises the following steps: S1, carrying out reaction on octa-epoxy polyhedral oligomeric silsesquioxane, aluminum trichloride, trichloromethane and diethylamine to obtain modified POSS; S2, enabling reaction of the modified POSS obtained in the step S1, peppermint oil and trichloromethane to obtain a peppermint oil compound; S3, enabling reaction of sodium polyacrylate, carboxymethyl cellulose, montmorillonite, deionized water, malic acid and aluminum hydroxide to obtain hydrogel powder; S4, uniformly mixing the hydrogel powder obtained in the step S3, a microcapsule phase change material and the peppermint oil compound obtained in the step S2 to obtain a hydrogel cooling component for later use; S5, uniformly mixing the hydrogel cooling component obtained in the step S4, an adhesive, a thickening agent and a solvent to obtain printing paste for later use; and S6, printing the printing paste obtained in the step S5 on cloth, and transferring the cloth into a vacuum oven for drying to obtain the hydrogel cooling cloth. The hydrogel cooling cloth prepared by the invention can reduce the temperature of a human body, so that the human body is dry and comfortable.

Description

Technical field [0001] The present invention relates to a method of preparing a hydrogel clear cloth. Background technique [0002] With the improvement of living standards, people have higher requirements for clothing fabrics, and comfort is one of the main needs. Among them, people have great demand for the cool and comfortable functions of summer clothing, hoping that the body temperature can be kept in a comfortable time during outdoor activities. Summer sun is strongly illuminated, people will be excessive in the living temperature, the body is sweating, and the sweat will soake the clothing cloth, adhere to the skin surface, the gas permeability, greatly affect the thermophysical comfort of the human body. Inventive content [0003] The technical problem to be solved by the present invention is to provide a preparation method of hydrogel cleaning cloth, which is made of hydrogel cooling to reduce the human body, so that the human body is dry and comfortable. [0004] In or...
