Problems solved by technology

However, because the conductivity of the white conductive component is poorer than that of conductive carbon black, there is still a big gap between the conductive performance of this method and that of carbon black conductive fibers.

Abstract

The invention relates to a high-performance polyamide-based dyeable conductive fiber and a preparation method thereof, belonging to the field of composite conductive fibers. The fiber provided by the invention employs a three-layer concentric circle structure which comprises three components, i.e., a highly-conductive medium carbon black component, a shielding composite substance component and a white conductive component in a mass ratio of 5-30%: 20-30%: 50-65%, wherein an inner layer, a middle layer and an outer layer are the highly-conductive medium carbon black component, the shielding composite substance component and the white conductive component respectively, or are the highly-conductive medium carbon black component, the white conductive component and the shielding composite substance component respectively. The fiber provided by the invention has improved conductivity and maintains original whiteness and dyeability. According to the invention, a metal oxide and a conductive intrinsic polymer are blended and granulated during preparation of white dyeable conductive master batch, so the characteristics of the two white conductive additive are integrated; and polyamide carrier resin is added to adjust a fusion index, so fluidity is improved, and the conductivity of the eventually prepared fiber is improved.

Description

technical field [0001] The invention relates to a composite conductive fiber, in particular to a high-performance nylon-based dyeable conductive fiber and a preparation method thereof. Background technique [0002] In recent years, with the vigorous development of polymer materials, the three major synthetic fibers - polyester, nylon, acrylic and polypropylene, a rising star, have occupied an important position in the fiber market due to their excellent performance. However, the surface of synthetic fibers can only be wetted by liquid whose critical surface tension is smaller than itself, and its volume resistivity is mostly 10 13 More than Ω·cm, so synthetic fibers are prone to static electricity. The existence of static electricity makes it easier for clothes to absorb dust and entangle each other, which seriously affects the production of high-precision instruments, biomedicine, food and other industries, and also increases the possibility of fire and explosion in flamma...
