Production method of high-performance conductive fiber

Abstract

The invention relates to a high-performance conductive fiber which is prepared from PP resin slice and conductive master batch. The PP resin slice is always positioned in the core layer of the conductive master batch. The content of the conductive master batch in the conductive fiber is 15-35 wt%. The formula of the conductive master batch comprises: by weight, 65-85% of polyamide and 15-35% of a conductive powder. Raw materials of the conductive powder comprise: by weight, 65-85% of germanium particles, 10-20% of nickel particles and 5-15% of silver particles. The conductive powder comprises the following components of: by weight, 2-12% of a coupling agent, 1.5-6% of a dispersant and 0.01-0.25% of an anti-oxidant. A production method of the conductive fiber comprises the following steps of: carrying out cladding and dispersion on the conductive master batch, uniformly dispersing it on the outside surface of the fiber-grade PP resin slice, and spinning to obtain the high-performance conductive fiber. The conductive fiber has excellent softness, spinnability and compliance, is light in volume, has large tensile strength and good conductivity, is widely applied, can be used to manufacture various fabrics for heating, warming and conducting current, and also can be used in antistatic and health-care functional fabrics.

Description

technical field [0001] The invention relates to the technical field of functional fibers, in particular to a production method of high-performance conductive fibers. Background technique [0002] With the rapid development of the textile industry, textiles have also ushered in a new era of rapid changes, so the corresponding conductive fibers for textiles are also coming out, because conductive fibers not only maintain the flexibility of ordinary fibers, but also have the characteristics of electrical conductivity, electric heating, shielding, Functions such as absorbing electromagnetic waves are widely used in textiles, from early antistatic radiation protection, electromagnetic shielding, conductive work clothes to current conductive textiles such as heating and health care clothing. Therefore, the development and application of conductive fibers are getting more and more attention. Looking at the relevant domestic research, the existing conductive textiles are mostly wove...

Problems solved by technology

Resistance wire is a kind of metal material, and its anti-breaking performance must be limited to a certain extent. It is easy to break when it is used on textiles that often need to be folded and kneaded. Hard, even the resistance wire will protrude from the surface of the textile, which not only affects the appearance but also makes it uncomfortable to use

Although the above-mentioned carbon fiber filaments have high strength, they are brittle materials, and they will not be deformed but directly broken when the force is too large, so they are basically irreparable after damage, causing permanent damage, and their functions are relatively single, which cannot achieve ideal practicality.
