Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the material of conductive fibers is mostly metal, and adding conductive fibers to the fabric will make the fabric feel harder. After the fabric is washed, the conductive fibers in the fabric will inevitably be damaged, resulting in conductive The fiber breaks and the anti-static performance of the fabric is reduced

Abstract

The present application relates to the technical field of fabrics, and specifically discloses an antistatic fabric and a production process thereof. The anti-static fabric includes a base layer and a surface layer, an anti-static layer is arranged between the base layer and the surface layer, and the anti-static layer is formed by coating the base layer with an anti-static coating, and the anti-static coating is composed of It is prepared from the following raw materials by weight: 20-30 parts of polyether polyol, 20-30 parts of polyester polyol, 10-15 parts of polyetheramine, 5-10 parts of graphene, and 4-6 parts of nano-tin dioxide , 10-15 parts of anhydrous ethanol, 0.5-1 part of film-forming aid, 1-3 parts of dispersant and 1-2 parts of sodium hypophosphite; the production process is: the base layer is steamed and shaped, and then the anti-static coating is applied Cover the base layer to form an anti-static layer, and then attach the surface layer to the anti-static layer, press and shape to obtain an anti-static fabric. The anti-static fabric of the present application still maintains a good anti-static effect after being washed with water for many times.

Description

technical field [0001] The present application relates to the technical field of fabrics, and more particularly, to an antistatic fabric and a production process thereof. Background technique [0002] Static electricity is a polarization phenomenon caused by the transfer of electrons from one object to another object under the action of external force or the influence of external electromagnetic fields, mainly caused by friction and motion. increase, and when it exceeds a certain value, spark discharge will occur. With the development of modern industry, static electricity is more and more harmful to production and life. Static electricity can lead to production failure, fire, explosion and secondary damage caused by electrostatic shock. In order to ensure the safety of people's lives and the safety of corporate products and corporate assets, it is necessary to use a large number of protective anti-static fabrics. [0003] Anti-static fabrics can be obtained by a variety o...
