The invention discloses a cotton fiber and jutecell fiber blended yarn and a spinning process thereof. The blended yarn comprises jutecell fiber with fiber content blending ratio as 70% and 30% fine staple cotton. The fibers are spun into yarns through the blended spinning process. Raw materials of the yarns are composed of the jutecell fiber and the fine staple cotton. Compared with the prior art where long staple cotton and jutecell fiber are used for blended spinning, the process is low in cost and high in cost performance. The blending mode of one pre-blending and three mixed-blending is adopted, so that the blending spinning ratio is accurate, and components are even. The blended yarns produced in the production process are high in single yarn strength, even in yarn levelness and few in nep and yarn fault. The yarn structure can further improve textile comfortableness, improve textile hand feel and improve lining grade.

The invention discloses a Siro-spinning core-spun yarn blended with soybean fiber and bamboo fiber and spinning technology. The blended yarn is produced by blending soybean fiber and bamboo fiber, wherein, the content of the soybean fiber is 1%-9%, and the residual is bamboo fiber. Siro-spinning is adopted; and spandex filament is added to produce Siro-spinning core-spun yarn. The blended yarn has the advantages of the soybean fiber and the bamboo fiber, at the same time, the spandex filament is added, so that the blended yarn has a good elasticity, a good shape-retaining ability, and has no wrinkling.

The invention relates to a yarn blended with silver fiber and cotton fiber and preparation technology, and the yarn is blended with silver fiber and combed cotton fiber through blending, wherein, the content of the silver fiber is 1-50%, and the balance is cotton fiber. The preparation technology comprises the steps of flower removing, cotton combing, preparation, fine combing, blending of silver fiber and combed cotton strip of combed cotton fiber, mixing, roving, spinning and automatic winding. The advantages are that the characteristics of both the silver fiber and the cotton fiber are provided; the yarn has high intensity, good wear resistance, moisture absorption, ventilation, strong antibacterial performance, and radiation hardening. The technology has the advantages that the blending ratio is accurate; the components are uniform; the blended yarn manufactured thereby has a strong force of a single thread, little hairiness, uniform strips, little cotton knobs and little yarn defects.

The invention discloses a cotton fiber and viscose blended yarn and a spinning technology thereof. The blended yarn comprises cotton fiber and viscose, and the fiber blending ratio of the cotton fiber to the viscose is 1:1; and the fibers are spun into yarns through a blending process. Card slivers formed by the processes such as blowing and carding and cotton fiber combed silvers are subjected to silver blending to form yarns, and a compact Silo spinning technology and the reasonable matching of raw materials are adopted, so that the problems such as the viscose can be deformed easily, has low elastic recovery performance and relatively low wear resistance, and is not acidproof are solved, and the advantages of the viscose and the cotton fiber are exerted. A pre-doubling and mixed doubling mixing mode is adopted, so that the accuracy of the blending ratio and the uniformity of ingredients are facilitated, produced single yarns have uniform yarn levelness and high strength, and few neps and yarn faults are produced.

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.
