Problems solved by technology

However, the ironing device involved in this method is only limited to heating the fiber strands in the triangular region to reduce the fiber modulus; and the thicker fiber strands of high-speed spinning cannot effectively reduce the fiber modulus in an instant, which is very important for improving the middle and low count yarns. Spinning quality effect is poor

Abstract

The invention relates to a soft and clean spinning method which can be used for improving the performances of yarn, especially the performances of yarn hairiness and belongs to the technical field of textile processing. On each drafting mechanism of a ring spinning frame, a roving sliver subjected to drafting is output from a front jaw, and a heat and moisture treatment device is used for performing on-line heat and moisture treatment on the on-line twisted roving slivers which are output from the front jaws and enter into a twisting triangular area. Under the combined action of heat and moisture, bending modulus and rigidity of fiber of the on-line twisted roving slivers are greatly reduced immediately, the softening speed and the degree are greatly improved, soft twisting and yarn forming can be performed on the thicker slivers when the lower modulus and the lower rigidity performance are achieved, and the ends of the fiber are easier to transfer and wind under the action of twisting torsional force and finally twisted into yarn bodies or attached on the surfaces of the slivers, thereby effectively eliminating hair feather in the formed yarn and greatly improving the degree of finish of the surface of the formed yarn. Simultaneously, the residual torque and residual stress of the ring-spun yarn can be reduced, not only can the entanglement phenomenon in the formed yarn be effectively solved, but also the softness of the formed yarn can be improved.

Description

technical field [0001] The invention relates to a soft and clean spinning method for improving yarn properties, especially yarn hairiness, and belongs to the technical field of textile processing. technical background [0002] Yarn hairiness not only affects the production efficiency of weaving, knitting and other subsequent processes, but also determines the appearance quality of the final product, so hairiness is one of the important indicators to measure yarn quality. [0003] It is generally believed that yarn hairiness occurs in the spinning process, increases in the winding process, and decreases in the sizing process. For ring-spun yarns, the fiber bundles are twisted in the twisting triangle to form yarns; at the same time, yarn hairiness is also produced. This is mainly due to the fact that in the twisting triangle area, the flat fiber strands output from the front rollers are twisted into circular yarns under the action of torque, at this time, the inner and outer...
