A low-hairiness vortex spinning method

Abstract

The invention relates to a method of low-hairiness vortex spinning. Fiber strands are led out from a feeding strand cylinder by a guide strand roller and a guide strand pressing roller; a solution with magnetic particles is sprayed on fibers in the fiber strands; the fiber strands with the magnetic particles are fed into the spinning device under effects of the roller; magnetic field pre-twisting is conducted on the fibers between a feeding roller and the fiber strand cylinder for once, so the fibers in the fiber strands are attached on fiber strand main bodies; the fiber strands obtained after pre-twisting are delivered into a drafting twisting device; the fiber strands are drafted and twisted to form yarns, and the yarns are led out by a front roller; the yarns are delivered into a vortex tube for re-twisting and are finally output by an output roller; and finished product yarns are obtained through winding of a reciprocating yarn guide device.

Description

technical field [0001] The invention relates to a novel spinning method, in particular to a low hairiness vortex spinning method. Background technique [0002] Yarn hairiness is mainly formed in the spinning process. When spinning on a ring spinning machine, there is a spinning triangle during twisting to form the yarn. Part of the fibers in the strands at the spinning triangle cannot be effectively controlled, and the ends of some free fibers cannot be twisted into the inner layer of the yarn during twisting and remain outside the main body to form hairiness. In addition, during the yarn forming process, the yarn is subjected to tension. The yarn tension causes the fibers in different positions in the yarn body to be subject to different centripetal pressures, resulting in repeated internal and external transfer of fibers in the radial direction of the yarn. During the transfer process, part of the fiber is squeezed out of the yarn body to expose the fiber end. These he...

Problems solved by technology

[0004] The above methods all use mechanical treatment to reduce the hairiness of the yarn, which has a certain effect, but also has a certain damage to the fiber, and will also damage the mechanical properties such as the strength of the yarn.
