Production method of combed polyester cotton yarn

Abstract

The invention discloses a production method of combed polyester cotton yarn. The production method comprises the following steps that 1, polyester staple fibers of 0.6-0.8 denier and soybean fibers of 1.1-1.2 deniers are subjected to a first blowing-carding process and a second blowing-carding process respectively for usage; 2, fine velvet cotton yarn is subjected to a third blowing-carding process, a pre-drawing process, a sliver and lap doubling process and a combing process for usage; 3, the polyester fibers and the soybean fibers obtained in the step 1 and the combed fine velvet cotton yarn obtained in the step 2 are subjected to a mixing and blending process, a roving process and a spinning process to be spun into 100-120 combed polyester cotton, wherein the combed polyester cotton comprises 60% of fine velvet cotton, 32-35% of polyester fibers and 5-8% of soybean fibers. According to the production method of the combed polyester cotton yarn, through an optimized cotton assorting method, the fibers cooperate with one another and are complementary in performance, the blending effect is good, the yarn strength is high, the hand feeling is good, the combed polyester cotton yarn has no cotton knots, compared with the same variety produced by originally using long velvet cotton, the Uster quality level of the produced combed polyester cotton yarn is higher, and the raw material cost is reduced by more than 2000 yuan per ton.

Description

technical field [0001] The invention belongs to the technical field of spinning and weaving, and more specifically relates to a production method of combed polyester-cotton yarn. Background technique [0002] With the improvement of people's quality of life and the change of aesthetic concept in recent years, the demand for polyester-cotton yarn products is increasing. In the traditional polyester-cotton carded yarn process route, the blending of polyester and cotton is completed by drawing frames. After the polyester-cotton and pure polyester staple fibers produced by the traditional process route pass through the carding process, the degree of carding cannot be achieved. Carding into a single fiber state, and electrostatic phenomena are prone to polyester neps. With the continuous advent of a variety of new fibers, especially green fibers, many new multi-component fiber blended yarns have emerged. These blended yarns can give full play to their respective fiber characteri...

Problems solved by technology

However, the raw material cost of long-staple cotton is relatively high. In order to ensure the quality of combed cotton and polyester yarn, the use of low-cost multi-fiber blending has become a research hotspot.
