Problems solved by technology

However, the principle of the heating fiber is to return the heat released by the human body to the human body, thereby reducing the heat loss of the human body and playing a role in keeping warm. Therefore, the self-heating in this way can improve the warming effect to a limited extent.

Abstract

The invention discloses a cloth with infrared heating function and a preparation method thereof. The surface of the cloth or cloth fiber contains an infrared absorbing coating, and the infrared absorbing coating is coated, sprayed or dipped with an infrared absorbing solution on the cloth or cloth fiber , obtained after UV curing. The cloth with infrared heating function and its preparation method provided by the present invention realize the infrared absorption of sunlight by clothes by adding an infrared absorbing coating on the cloth or cloth fibers, reduce infrared reflection, thereby realizing the self-heating function of clothes, phthalocyanine Dyes, nano-tungsten trioxide, nano-ATO, nano-GTO, nano-ITO, and nano-cesium tungstate can provide infrared absorption while retaining hydrophobic effect, which can increase the anti-fouling ability of clothes. After UV curing, the coating wear resistance High, simple and convenient preparation process, broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of functional fabrics, and in particular relates to a fabric with an infrared heating function and a preparation method thereof. Background technique [0002] Clothes with self-heating function have advantages in keeping warm and keeping out the cold in winter. In the prior art, in order to realize the self-heating of clothing, there are usually the following two ways to realize it: [0003] The first way is to add a heating module to the clothes, and the self-heating of the clothes can be realized through the heating of the battery. However, additional batteries and heating modules will not only increase the weight of the clothes, but also increase the risk of wearing and washing the clothes. [0004] The second way is to add heating fibers to the clothes or directly use the heating fibers to make clothes. Chinese invention patent, application number CN201810055988.X, discloses an anti-static self-heatin...
