However, high-count yarns have fine yarn counts and low strength, and are prone to end breaks during production, especially ultra-high-count yarns above 200S. At the same time, high-count yarns are mainly used in the production of high-end clothing fabrics, which require high yarn quality, so It is more difficult to produce high-count yarn

Abstract
The invention discloses ultra-high-count pure cotton combing yarn and a spinning technology of the ultra-high-count pure cotton combing yarn. Raw cotton comprises, by weight, 15%-25% of Egypt cotton, 25%-35% of American cotton and 40%-50% of Xinjiang long stapled cotton, wherein the Egypt cotton, the American cotton and the Xinjiang long stapled cotton are blended to spin 200S to 300S pure cotton yarn. The spinning technology includes the following steps that the first procedure of blowing-carding, the second procedure of combing, the third procedure of drawing, the fourth procedure of roving yarn, the fifth procedure of spun yarn and the sixth procedure of spooling. With the blending scheme, the raw cotton can integrate the advantages of high fineness and good maturity of the Egypt cotton, the advantages of high strength and non-existing abnormal fibers of the American cotton, the advantage of large length of the Xinjiang long stapled cotton and the like. The raw cotton reaches the requirements for the fiber length, the length CV value, the Micronaire value, the fineness, the strength and other performance indexes of raw cotton in producing ultra-high-count yarn. According to the spinning technology of the ultra-high-count pure cotton combing yarn, the ultra-high-count yarn can be produced under a large ration of roving yarn, the spinning efficiency is improved and meanwhile, quality of resultant yarn is ensured.
Description
[0001] technical field [0002] The invention relates to an ultra-high-count pure cotton combed yarn and its spinning process. Background technique [0003] At present, ring spinning, which realizes twisting through spindle rotation, is the most traditional spinning method, and it is also the most widely used spinning method in the market. The technology is very mature. Short new spinning technologies, such as rotor spinning, air-jet spinning, etc., especially air-jet spinning, have completely changed the twisting mechanism of ring spinning by using high-speed swirling airflow to make fiber bundles false-twisted and wrapped into yarns. The yarn method still cannot replace ring spinning in terms of raw material availability and overall yarn quality. It can be seen that the application number is: 201010520259.0; the title of the invention is: a heat-generating blended yarn and its spinning process. At present, ring spinning is still the most important method of spun yarn pro...
