Method for preparing high-performance conductive fiber

Abstract

The invention relates to a process for preparing high-performance conducting fiber, which comprises first, preprocessing, washing out foreign matters on the surface of fiber, second, coursing, adopting coursing agent to immerse fiber, and to improve the surface structure of the fiber, leading the surface to be roughness which is beneficial for absorbing metallic ion, third, sensitizing, utilizing stannous chloride or cadmium chloride solution to immerse fiber, leading the surface of fiber to absorb a layer of tin ions and cadmium ions, thereby forming a layer of metal catalytic layer, fourth, chemically coating silver, fifth, solidifying, utilizing oxalic acid solution to immerse, and getting end products after drying. The invention is simple and is easy to be operated, compared with the traditional electric plating, conducting fiber which is prepared by the invention has excellent electrical conductivity property, specific surface area specific resistance reaches 2-10 Ohm, and the characters of the original fibers are kept, the hand feeling is soft, and the invention can be applied in various commingled yarn fabrics.

Description

technical field [0001] The invention provides a preparation method of high-performance conductive fiber. In the method, a metal conductive thin layer is plated on the surface of ordinary fiber so that the fiber has antistatic and radiation-proof functions. Background technique [0002] With the continuous improvement of social productivity and the rapid development of science and technology, the process of urban modernization and industrialization is also getting faster and faster, and the resulting environmental pollution problems are becoming increasingly prominent. The arrival of the era of electrical appliances has gradually caused electromagnetic radiation pollution. Become another source of pollution after water pollution, air pollution and noise pollution. Crisis and opportunity coexist. After the popularization of electronic products, various anti-electromagnetic shielding products are born accordingly. As the clothes that are most closely related to people's daily ...

Problems solved by technology

1) Traditional electroplating method: this method needs to consume a lot of power resources, and cyanide-containing electroplating is very polluting to the environment; 2, cyanide-free electroplating method: the deep plating ability and throwing ability of this method need to be improved; 3) Vacuum sputtering coating method: This method requires relatively sophisticated experimental instruments, which is not conducive to the popularization of large-scale industrial production, and electroplating steps are required after vacuum coating
