Method and device for improving fiber yarn forming performance

Abstract

A method for improving the spinning performance of fibres features that the fibres are modified by a thermal shape-fixating equipment in their spinning procedure. Said thermal shape-fixating equipment is composed of internal tube and external tube. When the fibres pass through the internal tube, they are acted by high-temp steam to make their macro-molecular chains flexible and extended.

Description

technical field [0001] The invention relates to a method, a device and a related process capable of fundamentally improving the yarn-forming performance of textile fibers. The method belongs to the textile processing technology. Background technique [0002] There are two kinds of spinning processes, one is to assemble fibers with a certain length (tens to hundreds of millimeters) into a linear material for further processing. This spinning process usually goes through links such as carding, merging, drafting, twisting and winding. The other is the direct spinning of chemical fiber into yarn. In the former spinning process, two pairs of rollers with different speed ratios are used to draw and thin the fiber bundles to spin thinner yarns with uniform thickness. However, in the drafting zone of spinning, the surface of the fiber bundles is not constrained by the periphery, and some slow-speed fibers are squeezed and pulled by the fast fibers in the middle and front. It is e...

Problems solved by technology

For example, when the warp yarns are woven on the loom, the hairiness of adjacent yarns is easy to form entanglement, which makes the warp yarns unable to pass through the warp stopper, heald eyes and reed teeth smoothly, which is easy to cause broken ends; it will also cause the warp yarn opening to be unclear on the loom , especially the influence of hairiness on shuttleless looms is more prominent than that on shuttle looms

In addition, because the hairiness protruding from the yarn body is easier to dye than the fibers in the yarn body, resulting in color difference after dyeing gray fabric

At present, the main methods used in spinning mills are to control the temperature and humidity in the workshop and add lubricants (such as crude oil, etc.) to the fibers. These methods have limited effects, are prone to rust equipment, and cannot fundamentally improve the internal molecular chain of fiber bundles. supple performance
