Aramid fiber and carbon fiber blended yarn and production method thereof.

Abstract

The invention discloses aramid fiber and carbon fiber blended yarn formed by blending aramid fiber and carbon fiber in a mass part ratio of 1:1. The production method of the aramid fiber and carbon fiber blended yarn adopts the aramid fiber and carbon fiber as raw materials in the mass ratio of 1:1 and comprises the following steps of: firstly, preprocessing the aramid fiber and the carbon fiber, i.e. preadding an oiling agent to release static electricity; and sequentially carrying out the working procedures of blending, blowing, carding, drawing, roving, spinning and self-winding to make the aramid fiber and carbon fiber blended yarn. By adopting the aramid fiber and carbon fiber blended yarn and the production method thereof, the blended yarn has the performances of low density, resistance of high temperature, corrosion, friction and aging, high vibration attenuation property, electric and thermal conduction and optical penetration, low heat expansion coefficient, electromagnetic shielding property by non-magnet, and the like.

Description

technical field

[0001] The invention relates to the technical field of blended yarns, in particular to a blended yarn of aramid fibers and carbon fibers and a production method thereof. Background technique

[0002] With the progress of society and the vigorous development of all walks of life, people's requirements for material life are getting higher and higher, which makes the requirements for raw materials in production and manufacturing higher and higher. Like various textile fabrics, its uses are more extensive, such as used to make arc protective clothing, fire fighting clothing, etc. Due to the particularity of the application field, arc protective clothing and fire fighting clothing require high strength, abrasion resistance, corrosion resistance, and high temperature resistance. , high insulation characteristics, and at the same time have the proper comfort, which makes higher requirements for the yarn in the production process, and the existing ordinary yarn is us...
