Abstract

The invention relates to a three-axis compound spinning process for symmetrically protecting carbon fibers and application thereof. The three-axis compound spinning process for symmetrically protecting carbon fibers is characterized in that: a positioning tension wheel for controlling the feeding flattening and tension of carbon endless tows and a pair of bunching devices for controlling symmetrical positioning of chopped fiber yarn bars are arranged on an ordinary ring spinning machine; compound spinning for twisting, wrapping and protecting a bunch of carbon endless tows is performed by using two bunches of chopped fiber yarn bars which are fed symmetrically; and two bunches of chopped fiber yarn bars and a bunch of endless tows are fed synchronously in a three-axis form to form compound yarns in which the carbon endless tows are tensioned and enhanced inside and the chopped fiber yarn bars are coated softly outside. Due to the adoption of the process, the problem of difficulty in spinning yarns of fragile fibers at high strength in a non-bending way is solved.

Description

technical field

[0001] The invention relates to a triaxial composite spinning technology and application for symmetrically protecting carbon fibers, which belongs to the high-performance fiber composite spinning technology. Background technique

[0002] Carbon filaments are widely used in the industrial field due to their excellent mechanical properties, but brittle carbon filaments, and similar other fibers, such as glass fiber filaments, carbon fiber filaments, basalt filaments, and aramid filaments Silk is easy to bend, brittle, or fibrillated and split during processing and use, and its use and processing are limited. Therefore, it is necessary to take effective protection measures to protect these fibers through processing and convenient use.

[0003] At present, the spinning of such high-performance fibers is mostly staple fiber blending. Jin Yonglu's invention patent (patent number: 01106890.60) ramie aramid fiber blended yarn and its processing technology is to ble...
