Nylon carbon fiber and preparation process thereof

Abstract

The invention provides a nylon carbon fiber. The nylon carbon fiber comprises a core layer and a skin layer, and is prepared by composite spinning of the core layer made of a nylon material and the skin layer made of a carbon black material through a composite spinning assembly; the core layer deviates from the circle center of the skin layer and is not completely wrapped in the skin layer; a concave transition area is formed in the adjacent connection position of the core layer and the skin layer, and the core layer area of the transition area is in a sticky state through physicochemical treatment and is coated with a metal coating; and the nylon carbon fiber forms anisotropic manifestation on the periphery of the cross section by taking the geometric center as the center. The nylon carbon fiber disclosed by the invention has excellent electrical conductivity and anisotropy, has dual characteristics of nylon and carbon fiber, also has the advantages of metal fiber, is convenient for later manufacturing and treatment, and has application prospects in various fields.

Description

technical field [0001] The invention relates to the technical field of composite conductive fibers, and more specifically relates to a nylon carbon fiber and a preparation process thereof. Background technique [0002] With the development of science and technology, various industries have higher and higher requirements for the conductivity, antistatic properties and electromagnetic shielding properties of fabrics or clothing, and various proposals have been made for the manufacturing methods of conductive fibers. There are many types of conductive fibers, including metal-based conductive fibers, carbon black-based conductive fibers, conductive polymer fibers and metal compound-based conductive fibers. The conductivity of the conductive fibers prepared by these methods basically meets the needs of production and life, but there are inevitably many shortcomings. [0003] For example, metal-based conductive fibers mainly include pure metal wires made by multiple multi-strand ...

Problems solved by technology

[0005] The metal plating method is to treat the surface of ordinary fibers first, and then deposit metal on the surface of the fibers by vacuum spraying or electroless plating, so that the fibers have the same conductivity as metal, while the complete coating method used in the prior art will make Conductive fibers do not have anisotropy, and the post-processing is too limited. The plating layer on the surface falls off during the weaving process and subsequent processes, or the plating layer is easily dissolved and removed during the dyeing or refining treatment of the cloth. Difficult to achieve long-lasting conductivity
