A kind of flexible conductive yarn with carbon fiber fluff structure and preparation method thereof

Abstract

The invention relates to a flexible conductive yarn with a carbon fiber fluff structure and a preparation method thereof. The flexible conductive yarn is composed of carbon fiber fluff (that is, a carbon fiber monofilament bundle), a core yarn, an annular adhesive and an outer filament; the carbon fiber monofilament bundle is composed of n bundles are arranged in sequence along the axial direction of the core yarn, and each bundle is wrapped around the core yarn; a total of n ring-shaped adhesives are arranged at intervals along the axial direction of the core yarn, and each bundle is wrapped around the core yarn; In the direction X parallel to the axis of the core yarn, the front ends of each bundle of carbon fiber monofilaments are connected to each ring-shaped adhesive one by one, and the rear end of the previous bundle of carbon fiber monofilaments covers the front end of the next bundle of carbon fiber monofilaments; The filaments are spirally wound on each bundle of carbon fiber monofilaments; the method is: firstly, the adhesive is coated on the core yarn, then the carbon fiber monofilaments are adhered, then the adhesive is shaped, and finally the outer filaments are wound. The method of the invention is simple, and the conductive yarn is excellent in flexibility, conductivity, structural strength and wear resistance.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a flexible conductive yarn with a carbon fiber fluff structure and a preparation method thereof. Background technique [0002] At this stage, there have been many studies on linear conductive structures, which have been applied in many fields such as smart wearables, nanogenerators, electromagnetic shielding, and touch screens. In particular, flexible conductive wires are undoubtedly hot and difficult research points. Taking the field of smart wearables as an example, most of the conductive wires used are metal wires and conductive polymer materials. Metal wires have good electrical conductivity, but are too flexible. Poor, a wide range of applications cannot meet the characteristics of clothing, and conductive polymers have a certain degree of flexibility, but the conductivity is too low. In addition, carbon-based materials are often used as suitable objects, such as graphene an...
