The invention relates to a blended
yarn of Shu elastic silk fibers and cotton fibers and a
spinning process thereof. The blended
yarn has the advantages of the Shu elastic silk fibers and cotton, is transcendental in size stability, natural, soft, high in air permeability and
abrasive resistance, capable of being widely applied in the fields of cowboy costume, formal clothes, sport suit, knitted underwear and home
textile, and broad in market prospect. According to the preparation process, the difficulties that the Shu elastic silk which serves as
raw material fibers is high in elasticity and uneasy to reel separately and has too much crimps are overcome, the Shu elastic silk fibers and the cotton fibers are blended according to a blending proportion, and a cotton
carding process, a roving process and a spun
yarn process in the later period are completed. According to the process, the spun yarn process is adjusted, and the problem is solved that since the rebound resilience of the Shu elastic silk is high, coiling strips serving as raw materials are difficult to shape; a big-ration high-drafting process is achieved, the supply in the early period and the supply in the later period can be ensured, and the prepared blended yarns are high in single yarn intensity, small in variable coefficient and high in stability of
fiber strength, show excellent rebound resilience, and meet demands of downstream manufacturing.
