Less-hairiness low-torque spinning method

Abstract

The invention relates to a novel spinning method, in particular to a less-hairiness low-torque spinning method. According to the method, fiber strands are pulled out by a strand guiding roller and a strand guiding and pressing roller from a strand feeding canister, a solution containing magnetic particles is sprayed on the fibers in the fiber strands, the fiber strands with the magnetic particlesare fed into a spinning device under the effects of rollers, and pre-twisting based on a magnetic field is conducted on the fibers between a feeding roller and a fiber strand canister once to make thefibers in the fiber strands attached to the fiber strand bodies; the fiber strands after pre-twisting are subjected to extension twisting in the spinning device to form yarn, and the yarn is pulled out by a front roller and discharged by a discharging roller; after discharged by the discharging roller, the yarn passes through a rotary magnetic field and is subjected to inverse weak twisting again, an inverse twist degree is generated between the outer layer fibers of the yarn and the inner layer fibers of the yarn, and therefore the outer layer fibers of the yarn inversely wind around the inner layer fibers of the yarn, so that less-hairiness low-torque yarn is spun finally.

Description

technical field [0001] This application relates to a novel spinning method, especially a low-hairiness and low-torque spinning method. Background technique [0002] The hairiness of the finished yarn is mainly formed in the spinning process, and the amount of hairiness has a direct impact on the production efficiency of subsequent processing and the appearance of the fabric surface. Too much hairiness on the surface of the yarn will not only cause problems such as unclear texture on the fabric surface and uneven dyeing, but also easily block the holes and gaps in the yarn guide and knitting parts, affecting the weaving process. Therefore, it is necessary to further take corresponding measures to reduce hairiness. [0003] To reduce hairiness in ring-spun yarns, various methods have been developed. The compact spinning technology has been widely used in the market. By reducing the spinning triangle area, the hairiness of single yarn above 3mm is greatly reduced. But this m...

Problems solved by technology

[0005] However, the above methods all use mechanical treatment to reduce the hairiness and torque of the yarn, and all have certain effects, but they also have certain damage to the fiber, and the mechanical properties such as the strength of the yarn will also be damaged.
