Air vortex spinning method of multi-component full-colored spun yarns

Abstract

The invention discloses an air vortex spinning method of multi-component full-colored spun yarns, belonging to the technical field of novel spinning. The air vortex spinning method comprises the steps of: blending preprocessed dyed loose yarns according to a certain proportion, obtaining card slivers by cotton blending, blowing and cotton carding, obtaining drawn slivers by drawing and blending the card slivers for three times, and obtaining finished products by vortex spinning of the drawn slivers. The loose yarns comprise viscose, tencels, wools and spun silks at the mass percent ratio of 50:20:10:10; and 14 yarns for sweaters are spun. The air vortex spinning method of the multi-component full-colored spun yarns can meet multi-component full-colored spinning technical requirements and has the advantages of low cost, uniform coloring, no color difference and the like; and vortex spinning is applied to the color spinning field.

Description

technical field [0001] The invention relates to a spinning method for spinning multi-component full-color spinning yarn by using a novel vortex spinning technology, and belongs to the technical field of new spinning. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the individuation and comfort of clothing. In order to meet the market's demand for this aspect, the vortex spinning process is adopted with a short process, a high production rate, and a large saving The amount of labor required, the operation is relatively simple, and the strength and uniformity of the spun yarn are better than those of conventional technology. Not only can core-spun yarns be produced, but also double structures can be produced by using different lengths and shrinkages of fibers. The yarn can be spun into rich and colorful special yarns, so it is widely used. [0003] In order to meet consumers' requirements for the ...

AI Technical Summary

Problems solved by technology

[0003] In order to meet consumers' requirements for the diversification of fabric styles, various fibers are generally blended to obtain the advantages of different fibers. However, due to the different fiber properties of blended yarns, the temperature and pH required for dyeing Values ​​are different, multi-component yarn dyeing has always been more difficult, and it is difficult to level all the colors when registering

The method of color spinning can directly dye the fibers separately, avoiding the conflict of dyeing of fibers, and can also solve the conflict of color registration. As a new spinning technology, vortex spinning is widely used in knitting, sweater, weaving and other fields. In the field of color spinning, it is in its infancy. Traditional vortex spinning can only be used for polyester and viscose. This is because the characteristics of vortex spinning restrict fiber performance, and the influence of temperature and humidity on fiber requirements. Therefore, there is no successful precedent for color spinning of wool, spun silk and other fibers for semi-worsted spinning in vortex spinning production.
