Spinning process of combed cotton yarn

Abstract

An embodiment of the invention discloses a spinning process of a combed cotton yarn. The process comprises the steps of material selection, wherein the following raw materials in percentage by mass are selected: 20-30% of long stapled cotton, 20-30% of sea island cotton and 40-50% of Egyptian cotton; cotton cleaning; cotton carding, wherein combed noil fiber rolls are treated with a cotton cardingmachine to obtain cotton fiber slivers; drawing, wherein drawing is performed for three times; and spinning, wherein a full-automatic rotor spinning machine is adopted, the cotton slivers obtained bythe drawing process are fed into the rotor spinning machine, and air spinning is performed to obtain a cotton yarn product. An adopted spinning mode is compact siro spinning, the compact siro spinning combines the advantages of siro spinning and compact spinning, the spinning process is simple, the occupied area of a machine is small, the production cost is reduced on the basis of ensuring the product quality, and a theoretical basis is provided for development and research of preparation of an environment-friendly ordinary blended yarn. Furthermore, the rolling step in the cotton cleaning step can be reduced, so that the use of one machine is reduced and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a spinning process of combed cotton yarn. Background technique [0002] Cotton can be divided into three categories: the first category has long and thin fibers (within the range of 2.5 to 6.5 centimeters [1 to 2.5 inches] in length), lustrous, including sea-island cotton, Egyptian cotton and Pima cotton with excellent quality. Long-staple cotton has a low yield, requires a lot of labor, and is expensive. It is mainly used for high-grade gauze and knitwear; the second category includes general medium-length cotton, such as American upland cotton, with a length of about 1.3 to 3.3 cm (0.5 to 1.3 inches). The third category is cotton with thick and short fibers, about 1-2.5 cm (0.375-1 inch) in length, used to make cotton blankets and inexpensive fabrics, or blended with other fibers. Combed cotton itself is a kind of cotton. Combed is through the specific classification of the s...
