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.
