Segment color yarn spinning device and segment color yarn spinning method

Abstract

The invention provides a segment color yarn spinning device and a segment color yarn spinning method. The segment color yarn spinning device comprises a front roller, a middle roller and a rear roller, wherein the middle roller comprises a roller shaft; the roller shaft is connected with a first roller sleeve and a second roller sleeve from left to right; the front roller, the middle roller and the rear roller are driven by a first server motor, a second server motor and a third server motor respectively; a first bell mouth, a second bell mouth and a third bell mouth are additionally arranged at the upper parts of the front roller, the middle roller and the rear roller; the first roller sleeve is integrally connected with the roller shaft; the second roller sleeve is connected with the roller shaft through a bearing; and the bearing is connected with an electromagnetic switch. In the production process, main body rough yarns are fed into the rear roller from the first bell mouth, and auxiliary rough yarns are fed into the second roller sleeve of the middle roller from the second bell mouth; and the spinning of white yarn segments and colored yarn segments is realized by switching on / off of the bearing.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a segment colored yarn spinning device and spinning method. Background technique [0002] Segment colored yarn is a kind of fancy yarn, which is spun with fibers of different colors or raw materials. The color of the yarn is composed of a variety of colored fibers in the same cross section of the yarn. The fibers are in an irregular and intermittently changing distribution state. Duancai yarn fabric has soft and plump color, various patterns and strong sense of hierarchy, satisfying consumers' pursuit of fashion. At present, there are mainly four types of segment-colored yarn production technologies that are mainly used at home and abroad. These four segment-colored yarn production technologies all need to install a segment-colored yarn device on the corresponding production equipment, that is, a computer program controller to control the speed or operating cycle of t...

AI Technical Summary

Problems solved by technology

This mechanism can spin segment colored yarn with relatively evenness, but the adjustment and control of the roving weight and the draft ratio in the rear area are not convenient enough.

Three-roller spinning frame and four-roller spinning frame section colored yarn production device are only suitable for producing section colored yarn of two-color roving, the yarn color is relatively single, and the adjustment of color cycle is not flexible enough, and the dry quality of yarn needs to be improved
