Abstract

The invention relates to a carbon fiber-containing electro-thermal fabric suitable for a severe environment. A main body of the fabric is formed by weaving yarns. Electric channels consisting of carbon fibers are formed in the main body, and can be energized for heating. The carbon fibers are arranged in the main body in a way that carbon fiber heating filaments made from the carbon fibers are woven in the main body or a part or all of the yarns contain the carbon fibers. Various functional layers can be arranged on the surface of the fabric according to needs. The electro-thermal fabric is effectively waterproof, resistant to high temperature and low temperature, uniform in internal heating, small in vibration, low in noise and adapted to equipment heat preservation in various outdoor environments and long-distance / large-area snow removal and deicing of rails and the like, the shortcoming that the electro-thermal fabric cannot be used for the severe environment is overcome, and little spark discharge in the fabric is favorably reduced.

Description

technical field

[0001] The invention relates to an electric heating fabric, in particular to an electric heating fabric containing carbon fiber which can be used in harsh environments. Background technique

[0002] At present, the common electric heating element is a metal electric heating wire, which can usually adopt a spiral structure, and its outer surface can be wrapped with a fabric sheath for protection and / or insulation. This metal electric heating wire is laid in the middle of the fabric interlayer to form an electric blanket or the like. Flat electric heating products, the defects of this kind of electric heating products are: (1) Since the conduction and heating are concentrated on the heating wire, other parts of the product are not conductive and do not generate heat, so not only the heating is uneven, but also the heating wire itself has a higher calorific value , it is easy to cause local high temperature aging or even burning near the heating wire; (2) Since ...
