A kind of elastic silk fiber and cotton fiber blended yarn and its spinning process

Abstract

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.

Description

technical field

[0001] The invention relates to the textile industry, in particular to a yarn blended with elastic silk fibers and cotton fibers and a spinning process thereof. Background technique

[0002] "Shu elastic silk" is a new type of biomass elastic fiber jointly developed by Haixing Material Technology Co., Ltd. and DuPont of the United States, and has been exclusively authorized by DuPont. It uses DuPont's biomass material Sorona polymer and unique Produced by advanced clean processing technology, it is a perfect combination of biotechnology and fiber technology, and is currently the only biomass elastic staple fiber that can be industrially produced in the world. Its birth has completely rewritten the history that elastic staple fibers cannot be used in textiles, leaving a huge creative space for the development of new fabrics and clothing, and it is a revolutionary change in the textile industry. It can be widely used in sweaters, shirts, formal wear, denim, sp...

Embodiment 1

[0023] The blended yarn is formed by blending stretchy silk fiber and cotton fiber through a blending process. The spinning composition of the blended yarn is: 30% by weight of stretchy stretchy silk, and the balance is cotton fiber. The stretchy stretchy fiber is Raw material performance indicators: linear density 2.0Dtex, length 38mm, moisture regain 0.4%, the cotton fiber performance indicators are: length 32.6mm, single fiber strength 18.4cN / tex, fiber maturity and fineness grade (micronaire value) 4.0, moisture regain 7.3%;

[0043] The difference between the present embodiment 2 and the embodiment 1 is that the drawing gauge of the draw frame is 7×19 mm.

[0044] Product 1, basis weight 1.690g / 100m, total draft / rear area draft multiple 36.1 / 1.30, front pressure bar of jaw 2.5mm, air pressure 0.1Mpa, steel ring PG1 4254, traveler 6903 3 / 0;

[0045] The performance indicators of product one are: single yarn strength variation coefficient 6.8%, single yarn strength 13.5cN / tex, evenness 14.23%, strand 1, twist 98.0, twist coefficient 418, hai...

Embodiment 3

[0050] The difference between embodiment 3 and embodiment 1 is that the spinning composition of the blended yarn is: 60% by weight of elastic yarn, and the balance is cotton fiber.

[0051] The difference between this embodiment and the embodiment lies in that the tension of the carding net is adjusted to 1.17, and the draw distance is 10×23 mm.

[0052] Product 1, basis weight 1.776g / 100m, total draft / rear zone draft ratio 34.1 / 1.25, front pressure bar of jaw 2.5mm, air pressure 0.1Mpa, steel ring PG1 4254, traveler 6903 3 / 0;

[0053] The performance indicators of product one are: single yarn strength variation coefficient 7.3%, single yarn strength 13.0cN / tex, evenness 14.9%, strand 1, twist 100, twist coefficient 429, hairiness H value 4.02.

[0054] Product 2: Quantitative weight 1.419g / 100m, total draft / draft ratio of rear area 41.3 / 1.35, 2.5mm front pressure bar plus rear pressure bar at the jaw, air pressure 0.1Mpa, steel ring PG1 4254, traveler 6903 6 / 0;
