Problems solved by technology

However, due to the poor interfacial bonding between the conductive particles and the matrix polymer, the conductive performance of the top fiber is poor
[0004] In view of the above-mentioned related technologies, the inventor believes that there is a problem of unsatisfactory conductivity when using the blend spinning method to prepare conductive top fibers, which limits its use and development.

Abstract

The invention relates to the technical field of fiber products, and particularly discloses a high-conductivity wool top fiber and a preparation method thereof. The high-conductivity wool top fiber comprises a skin layer and a core layer, and the skin layer and the core layer form an eccentric skin-core structure. The core layer is prepared from the following raw materials: polyamide-6, polymer coated carbon nanotubes, a dispersing agent, a lubricating agent and a compatilizer; the skin layer is prepared from the following raw materials: polyamide-6, a conductive polymer and 4-dodecylbenzene sulfonate ions. The preparation method of the high-conductivity wool top fiber comprises the following steps: respectively mixing and extruding the raw materials of the core layer and the skin layer, and performing composite spinning to prepare the wool top fiber. The electrical conductivity of the core layer and the electrical conductivity of the skin layer are improved respectively, so that the obtained wool top fiber has excellent electrical conductivity.

Description

technical field [0001] The present application relates to the technical field of fiber products, and more particularly, to a high-conductivity top fiber and a preparation method thereof. Background technique [0002] The accumulation of static electricity is inevitable. When the static electricity is serious, it will burn people's skin. When the electromagnetic waves and harmful rays of various electrical appliances are excessive, the people's endocrine system will be dry. With the improvement of people's living standards and the enhancement of environmental protection awareness, in order to prevent electrostatic interference, people have developed various electrostatic products. In particular, the conductive clothing made of conductive top fibers has the functions of conducting electricity, conducting heat, shielding, and absorbing electromagnetic waves. Electromagnetic shielding covers for aviation and precision electronics industries. [0003] The conductive top fibers ...
