Abstract

The invention relates to a nanometer semi-conductive non-woven fabric and a processing technology of the nanometer semi-conductive non-woven fabric. The nanometer semi-conductive non-woven fabric is made of carbon fiber new materials through the advanced technologies like the high-strength spun yarn assisted net new process, the nanometer technology, the foam terylene layer technology and vacuum drying. The nanometer semi-conducive non-woven fabric has the advantages of being superior in semi-conductive performance, high in anti-tension strength, low in surface resistance and volume resistance and not prone to fading under high temperature. Besides, 'C' black on the surface cannot drop, efficiency is high, energy is saved, and environmental friendliness is achieved in a manufacturing process. The nanometer semi-conductive non-woven fabric is mainly used in cable core insulating layers of mine cables with 6KV and more than 6KV high voltage, shipboard cables with 6KV and more than 6KV high voltage and large-cross-section power cables with 10KV or more than 10KV and copper conductor surface taped coverings, capable of resisting strong electric fields and static, and semi-shielding. The nanometer semi-conductive non-woven fabric is also applicable to the development of indoor anti-static devices and anti-radiation shielding layers of medical and maternity anti-radiation clothes.

Description

technical field [0001] The invention relates to a nano-semiconductive non-woven fabric and a processing technology thereof, belonging to cable wrapping materials. Background technique [0002] At present, the production of semi-conductive non-woven fabrics at home and abroad is made by impregnating polyester fibers in conductive liquid and drying them. The disadvantage is that the inside of the fiber itself is not conductive, and it only relies on the "C" black component on the surface to conduct electricity after dipping. . Contents of the invention [0003] In view of the above defects, the present invention aims to provide a nano-semiconductive non-woven fabric and its processing technology. [0004] For this reason, the technical solution adopted by the present invention is: the present invention comprises a fiber web formed by interweaving conductive carbon fiber short fibers; the fiber web is longitudinally parallel with reinforced carbon fiber polyester yarn; the...
