A kind of preparation method of single hole supersoft yarn

Abstract

The invention belongs to the technical field of fiber spinning, and in particular relates to a preparation method of single-hole super soft yarn. In this method, cotton fiber and soluble fiber are firstly subjected to cleaning, carding and pre-drawing processes respectively to obtain cotton fiber pre-drawing and soluble fiber pre-drawing, and then cotton fiber pre-drawing and soluble fiber pre-drawing are passed through the feeder at the same time. into the device for drawing, and then through the roving, spun, winding, and water-soluble processes to obtain the final product. The method of the invention can successfully place the soluble fiber in the cotton fiber to form a single-hole super soft yarn.

Description

technical field [0001] The invention relates to a preparation method of single-hole super soft yarn, which belongs to the technical field of fiber spinning. Background technique [0002] Hollow yarn fabric is a new type of textile, which has good softness, warmth retention, excellent moisture absorption and quick-drying performance, and is light and bulky, so it is very popular among consumers. During the development of this yarn, the known methods of embedding soluble fibers in the center of the cotton yarn, through the ring spinning frame system, are as follows: [0003] The first method is to place the soluble fiber yarn at the core of the cotton yarn on the spinning frame, and insert the soluble fiber spun yarn into the sliver of the cotton fiber in the drafting area of ​​the spinning process for spinning. In the weaving process, due to The cotton fiber in the outer layer of the yarn has a tendency to slip into bundles, so that the soluble fiber is unevenly spread on th...

Problems solved by technology

[0003] The first method is to place the soluble fiber yarn at the core of the cotton yarn on the spinning frame, and insert the soluble fiber spun yarn into the sliver of the cotton fiber in the drafting area of ​​the spinning process for spinning. In the weaving process, due to The cotton fiber in the outer layer of the yarn has a tendency to slip into bundles, so that the soluble fiber is unevenly scattered on the surface of the yarn, resulting in uneven thickness of the yarn, and the hollow soft effect after being made into a towel is not obvious

[0004] The second is the drawing process in the spinning system, which is a spinning method in which the soluble fiber sliver (formed by carding) is placed in the center of the cotton sliver (formed after carding) and blended, because the fibers are uniformly spun during this process. The mixing of cotton fibers cannot guarantee that the soluble fibers will be evenly wrapped to form a hollow structure.
