Problems solved by technology

However, the electric heating wire and the electric heating tube are large in size, and there are problems of poor fit with textile materials and clothing, and poor comfort after wearing.
At present, technologies such as heating with graphene appear on the market, but graphene materials are not flexible, and cannot work normally under stress such as stretching and bending, especially in knees, elbows and other parts

Abstract

The invention provides a textile material with a flexible electric heating function and a preparation method of the textile material. The textile material is of a stack structure; the textile materialcomprises a first textile material layer, a first flexible insulation layer, a flexible heating layer, a second flexible insulation layer and a second textile material layer which are distributed sequentially from bottom to top; the flexible heating layer material is liquid metal and is electrically connected with one end of an electrode; and the other end of the electrode is connected with a power source. The liquid metal is heated under an electrified condition, so that the electric heating function of the textile material is realized. The textile material is comfortable to wear. The stability of the electric heating can be kept when the textile material is deformed. Therefore, the textile material has a bright application prospect in the field of clothes and other environments needingheating.

Description

technical field [0001] The invention relates to the technical field of textile materials and flexible electronic materials, in particular to a textile material with flexible electric heating function and its preparation method and application. Background technique [0002] Suitable temperature is a very important factor for human survival. Too low temperature can cause frostbite and even endanger human life. In the cold winter in northern my country, the traditional method of keeping warm is to wear thick cotton-padded clothes to prevent the loss of body heat and ensure that the body temperature is within the normal temperature range. However, the volume and weight of cotton-padded clothes are relatively large. On the one hand, wearing cotton-padded clothes has a strong sense of bloat, and on the other hand, it is not convenient to move freely. [0003] With the progress of society, people's requirements for clothing are gradually increasing, and clothing that is beautiful,...
