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.

Embodiment 1

[0054]A kind of preparation method of microporous super soft yarn, its specific steps are:

[0055] (1) Cotton fiber is made pre-drawing of cotton fiber through cleaning, carding and pre-drawing process;

[0056] (2) The soluble vinylon fiber is respectively prepared through the blowing, carding and pre-drawing process of the soluble vinylon fiber;

[0057] (3) The pre-drawing of cotton fiber and the pre-drawing of soluble vinylon fiber are carried out through the feeding device at the same time, and then the second drawing and the third drawing are carried out in sequence, and finally the roving, spun yarn, winding and water-soluble processes are processed. get the final product.

[0058] The length of the cotton fiber is 31.5mm, Micronaire A grade, and the short-staple rate is 8%; the main body length of the soluble vinylon fiber is 38mm, and the water melting temperature is 40°C.

[0059] In the drawing process, the cotton fiber pre-drawing mass percentage is 70%, and the...

Abstract

The invention belongs to the technical field of fiber spinning and particularly relates to a method for preparing multi-micropore super-soft yarn. The method comprises the steps of first causing cotton fibers and soluble fibers to respectively undergo blowing, cotton carding and pre-drawing to manufacture cotton fiber pre-drawing strips and soluble fiber pre-drawing strips; causing the cotton fiber pre-drawing strips and the soluble fiber pre-drawing strips to simultaneously undergo breaker-drawing through a feeding device and finally undergo secondary drawing and third-time drawing sequentially, and finally manufacturing the final product through roving, spinning, winding and water solution processes. By adoption of the method, the soluble fibers can be placed in the cotton fibers successfully, and the multi-micropore super-soft yarn is formed.

Description

technical field [0001] The invention relates to a method for preparing a microporous supersoft 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...
