A kind of roving method ab yarn production process

Abstract

The invention discloses a rough-yarn-method AB yarn production technology.The technology comprises the following steps that 1, mixed fibers of silver A are prepared according to the ratio and subjected to blowing, cotton carding and drawing to prepare drawing silver A; 2, mixed fibers of silver B are prepared according to the ratio and subjected to blowing, cotton carding and rough yarn to prepare rough yarn silver B; 3, the drawing silver A obtained in the step 1 and the rough yarn silver B obtained in the step 2 are subjected to the rough yarn combining working procedure to be prepared into rough yarn C; 4, the rough yarn C is subjected to the spun yarn working procedure and the spooling working procedure to prepare a finished product AB yarn.According to the AB yarn production technology adopting the rough yarn method, while the rough yarn working procedure is carried out, one piece of rough yarn and one piece of silver are fed from a rear roller and then spun into rough yarn, then the rough yarn is spun into yarn through a fine yarn machine, the color layers of the yarn are rich, hand feeling is full and smooth, tension is uniform, and less hairiness is generated; compared with a fine yarn method in the prior art, the requirement of the rough yarn for the fiber composition difference between yarn A and yarn B is low.

Description

technical field [0001] The invention relates to textile technology, in particular to a production technology of AB yarn by roving method. Background technique [0002] AB yarn production methods in the prior art are spinning method and drawing method. The spinning method is to use the Siro spinning technology on the spinning frame, and feed two rovings at the same time to make yarn; the drawing method is to feed two different components or colors in the drawing process to spin the mature strips, and then pass through the rovings. , The spinning process is spun into yarn. The synchronous twisting in the same direction of siro spinning makes the yarn have a special structure. The surface fibers of siro spinning are arranged neatly, the yarn structure is tight, the hairiness is less, and the anti-pilling is good. Compared with ply fabric, siro fabric has a softer and smoother feel. Siro spinning can be used in woven and knitted fabrics, and can also replace strands in high-c...

Problems solved by technology

The mixed color of AB yarn produced by drawing frame is relatively uniform, and the color level is not rich enough

In order to realize the spinning method production of AB yarn, it is necessary to modify the spinning machine, such as adding hanging spindles and replacing the double-hole yarn guide horn, increasing the original 6 rows of hanging spindles to 8 rows, and the roving supply is prone to shortage during the spinning process There may even be a phenomenon that the roving supply of a certain raw material is out of joint due to the large difference in the speed of the roving due to the thicker yarn count and the difference in the properties of the AB raw materials; As close as possible, the maximum difference is not more than 10%, otherwise it is easy to cause skewing of the spun yarn rubber roller and single spinning; after the AB yarn is formed into a yarn, the two colored yarns are alternately distributed, and the longitudinal direction is spiral, and the color of the whole yarn The uniformity is not stable enough, and it is easily affected by the uniformity of single yarn thickness
