Abstract

The invention discloses an antibacterial conductive fiber and a preparation method thereof. The antibacterial conductive fiber comprises a skin layer containing an antibacterial agent and a resin matrix, and a core layer containing an antibacterial agent, a conductive component and a resin matrix, wherein the content of the antibacterial agent is gradually reduced from the skin layer to the core layer, the area of the radial section of the core layer is gradually reduced by extending from the geometric center of the radial section of the fiber to the skin layer, at least three extending ends are formed, and the ends of the extending ends on the radial section are all curves with certain curvatures. The core layer of the provided antibacterial conductive fiber adopts the special-shaped section, so that electrostatic charges generated by the composite fiber in friction are concentrated at the extending ends of the core layer, the charges are dissipated by utilizing a point discharge phenomenon, and an antibacterial agent gradient formed from the core layer to the skin layer provides a lasting antibacterial effect for the fiber.

Description

technical field [0001] The invention belongs to the technical field of chemical fibers, and in particular relates to an antibacterial conductive fiber and a preparation method thereof. Background technique [0002] In the current manufacturing environment, electrostatic grounding is one of the main measures to prevent electrostatic hazards. Using a direct or indirect electrostatic grounding system can make the charge on the charged body leak and dissipate to the ground, thereby avoiding electrostatic hazards. However, in actual production, some occasions cannot achieve complete electrostatic grounding. In this case, it is generally necessary to adopt the method of equipotential connection, that is, to conduct conductive connection of multiple objects without good conductive paths between each other, so that each object They are roughly at the same potential with each other, but this measure still has certain risks. In order to solve these problems, anti-static supplies are ...
