Problems solved by technology

Moreover, during the blending process, the fibers are seriously damaged and the short staples increase, resulting in a decrease in the quality of the obtained polyester-viscose blended yarn, which in turn brings hidden dangers to the subsequent dyeing and finishing processes.

Embodiment 1

[0017] Using ordinary polyester medium-long fiber, viscose medium-long fiber, and cross-type polyester medium-long fiber as raw materials, the ordinary polyester medium-long fiber and viscose medium-long fiber are mixed, and the drawing is made by opening, carding, and drawing. A. Roving, viscose medium-long fiber and cross-type polyester medium-long fiber are mixed, after opening and cleaning cotton, carding, and drawing to make draw frame B, roving, draw frame A and draw frame B after roving are mixed into a frame Draw C, draw sliver C is spun yarn, automatically winded into yarn, inspected and packaged, and put into storage. Among them, the weight ratio of ordinary polyester medium-long fiber to viscose medium-long fiber in Draw A is 50:15. Take and feed into the opener, using a three-wing comb needle beater, the beater speed is 500r / min, the distance between the beater and the dust stick in the opener: the inlet is 12mm, the middle is 13mm, and the outlet is 16mm; dust The ...

Embodiment 2

[0019] Using ordinary polyester medium-long fibers, viscose medium-long fibers, and cross-type polyester medium-long fibers as raw materials, ordinary polyester medium-long fibers and cross-type polyester medium-long fibers are artificially loosened, and 2wt% of antistatic agent is added to wet Add milk and stack the warehouse for 24 hours to make it evenly permeate and control the moisture regain within 3-5%. The antistatic agent is made by making 2wt% sodium alginate aqueous solution from sodium alginate extracted from kelp, and then adding 1wt Made of% mussel mucin. Mix ordinary polyester medium and long fibers with viscose medium and long fibers, and make draw A and roving after opening, carding and drawing. The viscose medium and long fibers are mixed with cross-type polyester medium and long fibers, and the cotton is opened and cleaned. , Carding and drawing to make draw frame B and roving. Draw frame A and draw frame B after roving are mixed into draw frame C. Draw frame...

Abstract

The invention discloses a polyester-viscose blended yarn production technique. Ordinary polyester medium staple fiber, viscose medium staple fiber and cross-shaped polyester medium staple fiber are used as raw materials, ordinary polyester medium staple fiber and viscose medium staple fiber are mixed and subjected to blowing, cotton carding, drawing to obtain combined sliver A and roving, viscose medium staple fiber and cross-shaped polyester medium staple fiber are mixed and subjected to blowing, cotton carding, drawing to obtain combined sliver B and roving, the combined sliver A after roving and the combined sliver B after roving are mixed into combined sliver C, the combined sliver C is subjected to spinning and automatic winding to obtain yarn, and the yarn is detected, packaged and then stored. The weight ratio of ordinary polyester medium staple fiber to viscose medium staple fiber in the combined sliver A is (40-60):(10-20), and the weight ratio of viscose medium staple fiber to cross-shaped polyester medium staple fiber in the combined sliver B is (5-7):(10-20). The obtained yarn is straight, smooth and high in toughness.

Description

Technical field [0001] The invention relates to a production process of polyester-viscose blended yarn. Background technique [0002] Blended yarn refers to a yarn made by mixing two or more different fibers in a certain proportion, such as polyester-cotton blended yarn, polyester-viscose blended yarn, etc. In the current spinning project, the production process of polyester-viscose blended yarn usually adopts the following mixing methods: small amount of cotton, cotton grabbing machine mixing, and drawing and mixing. This kind of mixing method is evenly mixed, but after the spun yarn is woven into a fabric and dyed, the fabric surface cannot show the hazy layering formed by the dyeing of different fibers. At the same time, most of the polyester fibers used are conventional, single-variety fibers, and the spun yarns have their own characteristics. Moreover, in the blending process, the fiber is seriously damaged and the lint is increased, resulting in a decrease in the quality ...
