A kind of production device and production method of two-color colored yarn

Abstract

The invention provides a double-color-section colored yarn production device and method. The double-color-section colored yarn production device comprises a front roller, a middle roller and a rear roller, wherein a front leather roller, a middle leather roller and a rear leather roller are arranged at the upper parts of the front roller, the middle roller and the rear roller respectively; the middle roller comprises a middle roller shaft; the middle roller shaft is connected with a left middle roller sleeve and a right middle roller sleeve; the left middle roller sleeve and the middle roller shaft are integrally connected; the right middle roller sleeve is connected with the middle roller shaft through a bearing; the bearing is connected with an electromagnetic switch; the rear leather roller comprises a left rear leather roller and a right rear leather roller; the diameter of the left rear leather roller is greater than that of the right rear leather roller; the front roller, the middle roller and the rear roller are independently driven by a servo motor respectively; a rear bell mouth is additionally arranged at the upper part of the rear roller; the rear bell mouth comprises a left rear bell mouth and a right rear bell mouth; and a front bell mouth is additionally arranged at the upper part of the front roller. In a production process, first rough yarns are fed from the left rear bell mouth and second rough yarns are fed from the right rear bell mouth; and the first rough yarns and the second rough yarns are discontinuously fed through on / off switching of the bearing.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a production device and production method for double-color colored yarn. 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 operati...

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
