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.
