Abstract

The invention provides a composite spinning device and a spinning method for covering rigid fiber filaments with chemical fiber filaments. The composite spinning device comprises a ring spinning frame, and is characterized by also comprising an unreeling roller, a positioning yarn guide, a tension disk and a multi-position yarn guide, wherein the positioning yarn guide is positioned behind a feed jaw of a front roller pair of the ring spinning frame; and the multi-position yarn guide is positioned in front of an output jaw of the front roller pair of the multi-position yarn guide. The rigid fiber filaments which unreeled from a rigid fiber filament drum pass through the unreeling roller and the positioning yarn guide in sequence and then are converged with two bundles of chemical fiber filaments which are unreeled from a chemical fiber filament drum, are fed into the front roller pair through the tension disk and the multi-position yarn guide and are output from the front roller pair at a convergent point; meanwhile, the chemical fiber filaments and the rigid fiber filaments are twisted at the convergent point to form a composite yarn under the action of rotation of a spindle of the ring spinning frame. Through the device and the method, the problems of high brittleness of carbon fibers and high probability of bending and brittle fracture of fibers during back-roll and weaving can be solved.

Description

technical field [0001] The invention relates to a composite spinning device and spinning method in which chemical fiber filaments are coated with rigid fiber filaments. Background technique [0002] Carbon fibers have long been known as fibers suitable as structural materials and reinforcing composite materials. Because carbon fiber has high strength, high modulus, and excellent properties such as light resistance, heat resistance, and corrosion resistance, it is compounded with other materials to strengthen and last. However, carbon fiber is very brittle, and it is very prone to bending and brittle fracture of the fiber during rewinding and weaving processing. Therefore, the commonly used carbon fiber composite materials are firstly preformed and then coated with resin to solidify the structure and composite materials into the desired shape. Due to the bending, friction and other damages in the weaving process, in order to protect the carbon filaments, dipping Glue, oilin...
