Embodiment 1

[0034] In this embodiment, polyester is used as the base fiber

[0035] The first step is pretreatment. Soak the fiber with a solution of commercially available white cat detergent and absolute ethanol at a ratio of 1:4 (mass / volume). The soaking time is generally 10 to 20 minutes, depending on the cleanliness of the fiber. Depends on to remove surface stains and other impurities.

[0036] In the second step, roughening, the fiber is surface-treated by soaking it in 1,2-dichloroethane for 20 minutes to increase its surface area and roughen its structure.

[0037] The third step is sensitization. The fiber is soaked in 2g / L tin dichloride solution for 20 minutes to form a thin metal catalytic layer on the surface.

[0038] The fourth step, electroless silver plating

[0039] Silver nitrate, ethylenediamine, sodium hydroxide and deionized water are mixed to form an aqueous solution, and potassium sodium tartrate solution is added before the reaction to form a silver-plating re...

Embodiment 2

[0048] In this embodiment, nylon is used as the matrix fiber

[0049] The first step, pretreatment, soaks the fiber with 1g / L sodium hydroxide solution for 10 minutes to remove surface stains and other impurities.

[0050] In the second step, roughening, the fibers are surface-treated by soaking them in xylene for 10 minutes to increase their surface area and roughen their structure.

[0051] The third step is sensitization. The fiber is soaked in 5g / L cadmium chloride solution for 20 minutes, so that a very thin metal catalytic layer is formed on the surface.

[0052] The fourth step, electroless silver plating

[0053] Mix silver nitrate, ammonia water, sodium hydroxide and deionized water to prepare an aqueous solution, and then add the prepared aqueous solution of tartaric acid, glucose and absolute ethanol before the reaction to prepare a silver plating reaction solution. The content of each of the above substances is:

[0054] Silver nitrate 3g / L

[0055] Ammonia 10m...

Embodiment 3

[0064] In this embodiment, high-elastic nylon is used as the matrix fiber

[0065] The first step is pretreatment. Soak the fibers with a solution of commercially available white cat detergent and absolute ethanol at a ratio of 1:2 (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.

[0066] In the second step, roughening, the fiber is surface-treated by soaking it in 1,2-dichloroethane for 15 minutes to increase its surface area and roughen its structure.

[0067] The third step is sensitization, soaking the fiber with 1.8g / L tin dichloride solution for 15 minutes to form a thin metal catalytic layer on the surface.

[0068] The fourth step, electroless silver plating

[0069] Silver nitrate, ethylenediamine, sodium hydroxide and deionized water are mixed to form an aqueous solution, and potassium sodium tartrate solution is added before the reaction to form a silv...

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 ...
