1088 results about "Combing" patented technology

Combing is a method for preparing carded fibre for spinning. Combing is divided into linear and circular combing. The Noble comb is an example of circular combing. The French comb is an example of linear combing. The process of combing is accompanied by gilling, a process of evening out carded or combed top making it suitable for spinning. Combing separates out short fibres by means of a rotating ring or rectilinear row of steel pins. The fibres in the 'top' it produces have been straightened and lie parallel to each other. When combing wool, the discarded short fibres are called noils, and are ground up into shoddy.

Technological process of ramie bast fiber

The invention relates to a technological process of a ramie bast fiber, which comprises a basic degummed ramie production route: raw ramie skin-sorting and derooting-mechanical ungluing-cage loading-biological ungluing-high-temperature rinsing-cage unloading-sub-fiber washing-soft rinsing-radio frequency drying- degummed ramie. Long ramie can be growth through the mechanical hemp oiling- infiltration and health care-stretch breaking and carding-pre-gilling-combing and sorting-final gilling of the degummed ramie. Short ramie can be produced through the combing and the sorting of combed noil. Oakum can be produced through biological ungluing-high-temperature stewing and ungluing-high-temperature rinsing-cage unloading-sub-fiber washing-soft rinsing-dehydration and drying-radio frequency drying-mechanical hemp oiling- infiltration and health care-opening and edulcoration- combing and sorting. Improving methods are adopted for the mechanical ungluing, biological ungluing, high-temperature rinsing, sub-fiber washing, stretch breaking and carding, combing and sorting and the like. The preparation process has the advantages of short process, high production efficiency, high mechanical automation degree, stable product quality, excellent fiber quality and strong operability of fiber length and fineness, and can be used in the production processes of various bast fiber raw material, gramineae fiber raw material, leaf fiber raw material and other fibers.

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.
