Embodiment 1

[0058] In this embodiment, nylon is used as the matrix fiber

[0059] The first step is pretreatment. Soak the fibers with a solution of commercially available white cat detergent and absolute ethanol at a ratio of 1:5 (mass / volume). The soaking time is generally 10 to 20 minutes, depending on the cleanliness of the fibers. Depends on to remove surface stains and other impurities.

[0060] In the second step, roughening, the fiber is soaked in 1,2-dichloroethane for 20 minutes, and its surface is treated to increase its surface area and roughen its structure.

[0061] The third step, sensitization, is to soak the fiber with 2.5g / L tin dichloride solution for 15 minutes, so that a very thin metal catalytic layer is formed on the surface.

[0062] The fourth step, activation, soaks the fiber with 0.02g / L palladium chloride solution for 20 minutes.

[0063] The fifth step, electroless copper plating

Abstract

The invention relates to a method for preparing a high performance conductive fiber, which comprises the following steps: V1ing, pretreatment and washing. V2ing, fiber is socked by coarsening agent to improve the surface structure of the fiber. V3ing, the fiber is socked by stannous chloride or cadmium chloride solution, and a layer of tin ions or cadmium ions are adsorbed on the surface of the fiber. V4ing, the fiber is socked by palladium chloride solution, and the tin ions or cadmium ions which are replaced by palladium colloid are adsorbed on the surface of the fiber. V5ing, electroless copper plating. V6ing, after being socked by oxalic acid solution, the fiber is dried. V7ing, the fiber which is plated with copper is socked and treated by tin dichloride solution. V8ing, the copper-plating fiber is socked by palladium chloride solution, and the tin ions or cadmium ions which are replaced by palladium colloid are adsorbed on the surface of the fiber. V9ing, chemical nickel plating. V10ing, after being socked by deionized water, the fiber is dried, and a product is obtained. The invention has small pollution to environment and less energy dissipation, and is easy to industrially produce. The conductive fiber which is prepared using the invention has excellent conductivity, the resistance of the specific surface area is 1-10 ohm, the original characteristics of the fiber is preserved, and the high performance conductive fiber is capable of being used for various non-woven 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 ...
