Carbon fiber yarn production process

Abstract

The invention relates to a carbon fiber yarn production process. The carbon fiber yarn production process uses carbon fiber yarn processing and manufacturing equipment, wherein the equipment comprises a water tank and a tensioning device arranged in the water tank, and a drying device is arranged on the outer side of the water tank. Through cooperation of a gear, an incomplete gear, a rotating plate, a flapping column and a telescopic spring, the incomplete gear can drive the gear to rotate intermittently, the gear drives the rotating plate to swing, the rotating plate can return to the original position under the action of the elastic force of the telescopic spring, and therefore water-washed carbon fibers are flapped; vibration is generated on the surfaces of the washed carbon fibers, so that moisture on the surfaces of the washed carbon fibers can be vibrated and sieved, and the surfaces of the washed carbon fibers can be conveniently dried in the later period; and through cooperation of a first transmission belt, cotton cloth and extrusion rollers, the first transmission belt can drive the cotton cloth to rotate together, and therefore secondary water removal can be carried out on the carbon fiber yarns obtained after vibration screening.

Description

technical field [0001] The invention relates to the field of fiber filaments, in particular to a production process of carbon fiber filaments. Background technique [0002] Carbon fiber is a composite material prepared from carbon fiber and related matrix resin. It is a special fiber composed of carbon elements, and its carbon content varies with different types. Carbon fiber has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. Orientation has high strength and modulus. The density of carbon fiber is small, so the specific strength and specific modulus are high. [0003] Carbon fiber filaments are composed of composite materials prepared from carbon fibers and related matrix resins, and are carbonized in a carbonization furnace. In order to be better used in the production of composite materials, it is necessary to use ammonium bicarbonate neutral electrolyte on the surface of c...

AI Technical Summary

Problems solved by technology

[0005] 1. During the winding process, due to insufficient tension, the surface of the carbon fiber filament will be in a loose state, and the surface cannot be fully contacted, which may easily cause position deviation;

[0006] 2. When using a fan or an oven to remove water from the surface of carbon fiber filaments, it is difficult to control the temperature, and it is easy to cause changes in the internal properties of carbon fiber filaments, and consume power, resulting in high costs
