Spinning method for bundling and pressing fiber strands

Abstract

The invention relates to a spinning method for bundling and pressing fiber strands, and belongs to the technical filed of textile processing. According to the invention, a bundling and pressing device is additionally arranged on a front drafting zone separation block of a ring spinning frame, so that the cross section width of fiber strands in a front drafting zone can be controlled in an on-line manner, the edge fibers of fiber strands in a twisting triangle area of spun yarns can be reduced, the diameter of the cross section of a resultant yarn is reduced, the structure of the resultant yarn is more compact; besides, the additional friction force field of the front drafting zone is vertically reinforced to control the variable motion of fibers in fiber strands of the front drafting zone. The spinning method provided by the invention can remarkably reduce the hairiness of the resultant yarn, improve the yarn evenness and strength of the resultant yarn, besides reduces the possibility of forming air bellow yarns caused by the fact that edge fibers in the twisting triangle area of spun yarns are absorbed by a yarn absorbing pipe, and facilitates improving the yield of spun yarns. The spinning method for bundling and pressing fiber strands, provided by the invention, is convenient to operate, and slightly influences the operation of tenders.

Description

Technical field [0001] The invention relates to a spinning method for performing bundling and pressure treatment on the whiskers, in particular by adding a device for bundling and pressurizing the whiskers on the existing spinning equipment, belonging to the technical field of textile processing. technical background [0002] Hairiness is one of the important indicators to measure yarn quality. Yarn hairiness not only affects the production efficiency of weaving, knitting and other post-processes, but also affects the appearance quality of the final product. Especially when shuttleless looms are commonly used today, reducing yarn hairiness is of great significance. [0003] In terms of controlling yarn hairiness, scholars at home and abroad have done a lot of research. There are two methods commonly used, one is to use conventional methods, and the other is to develop special hairiness reduction devices to eliminate hairiness. The conventional method is to reduce the generation o...

Problems solved by technology

The main difference of these studies is that the direction of force on the fibers on the surface of the yarn is different due to the different air injection devices, resulting in different winding effects and resulting in different yarn hairiness elimination effects.

At the same time, these devices must be equipped with special air compression equipment and pipelines, and the structure is complex. Installing on the spinning frame has a great impact on the joint operation of the car operator, and consumes a lot of energy.
