Embodiment Construction

[0013] A vortex spinning method, the method sequentially includes the processes of picking cotton, blending, opening, carding, roving, and spinning, and the fibers are applied with auxiliary agents containing magnetic particles in the process of opening and carding, and the strands are fed into the The vortex spinning drafting and twisting device performs drafting and twisting to form a yarn that is output by the output roller. The yarn passes through the output roller and then passes through the rotating magnetic field device for another weak twisting, and the reciprocating yarn guide is wound into a finished yarn.

[0014] In the carding process, a small cylinder tooth pitch and a small tooth groove depth are used. The rotating magnetic field device includes a circular magnetic field generator, a magnetic field frequency controller, power supply equipment, an adjusting device, and a permanent magnet. The rotating magnetic field device uses an alternating current to form a st...

Abstract

The invention relates to a vortex spinning method, in particular to a low-hairiness-rate vortex spinning method. Fiber strands are guided out from a feeding can by a strand guiding roller and a strandguiding compression roller, fiber on the fiber strands is sprayed with a magnetic particle solution, the fiber strands with magnetic particles are fed into a vortex spinning device under the effect of the roller, the fiber strands are drafted and twisted in the vortex spinning device to form yarns, then the yarns are guided out by a front roller, enter a vortex tube to be twisted again and finally are output by an output roller, the yarns undergo one-time weak twisting again behind the output roller through a rotating magnetic field to make the fiber in the fiber strands further attached to yarn bodies, and finished product yarns are obtained through winding of a reciprocating yarn guider.

Description

technical field [0001] The invention relates to a vortex 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 h...
