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

preparation example Construction

[0041] The invention also discloses a preparation process of nylon carbon fiber, which includes the following steps: step S1, heating nylon material and carbon black material to form a melt, and transporting the two melts into the composite spinning assembly through their respective delivery pipelines , independently distributed and conveyed through the respective flow channels of the melt inside the composite spinning assembly, and finally extruded through the special-shaped hole at the exit of the composite spinning assembly, and entered into the cooling liquid for forming; S2 step, the formed nylon carbon fiber is passed through electromagnetic induction Heating by means of heating, so that the skin layer 2 in the nylon carbon fiber is heated to 20-50 ° C, and the heat source in the transition zone 3 is deposited, causing the surface of the core layer 1 to expand when heated, and the micropores on the surface are opened to form a sticky layer that is easy to adhere to the met...

Embodiment 2

[0047] There are multiple core layers 1, which are symmetrically distributed around the center of the skin layer 2. The core layer 1 is compounded with the skin layer 2 through a unique composite spinning assembly, so that the prepared preliminary nylon carbon fiber is evenly spaced and arranged with multiple pairs of transition regions 3, and can be processed on the nylon carbon fiber at the same time The multi-point coating improves the overall performance of nylon carbon fiber. While ensuring the weight of nylon carbon fiber itself, it can obtain more excellent ductility, conductivity, wear resistance and electromagnetic shielding ability.

[0048] Except for the above distinguishing features, other technical features refer to Embodiment 1 and will not be repeated here.

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 ...
