Multi-moire-color blended yarn and production device and method thereof

Abstract

The invention discloses a multi-moire-color blended yarn and a production device and method thereof. A rough yarn is fed into a super-draft spinning frame through a front-middle roller, and three fine yarns are fed into the super-draft spinning frame through a rear roller, a rear-middle roller and the front-middle roller respectively, wherein the super-draft spinning frame comprises four rollers, four rubber rings and three draft regions. A hollow gathering roller with the diameter of 50 mm is adopted as the front roller, and strip-shaped grooves or round holes are formed in the surface of the hollow gathering roller; meanwhile, the rear roller, the rear-middle roller, the front-middle roller and the front roller are controlled by independent servo motors respectively, and the gathering region of the front roller is open and is connected with a fiber conveying pipe. In this way, the multi-moire-color blended yarn is produced. Three identical main rough yarns and three kinds of fine yarns with different colors are adopted and fed in through the rear roller, the rear-middle roller and the front-middle roller respectively, in cooperation with independent servo motor control over the four columns of rollers, production of the yarn with three different moire colors can be achieved, and the additional value of the yarn can be increased; the fiber conveying pipe is adopted for evenly drawing villous fibers difficult to spin into yarn bodies of the main fine yarns, and therefore production of the functional blended yarn can be achieved.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a multi-moiré color blended yarn and its production device and production method. Background technique [0002] Ring spinning, which achieves twisting through spindle rotation, is the most traditional spinning method, and it is also the most widely used and most common spinning method in the market. The technology is very mature. New spinning technologies, such as rotor spinning, air-jet spinning, etc., especially air-jet spinning, have completely changed the twisting mechanism of ring spinning by using high-speed swirling airflow to make fiber bundles false-twisted and wrapped into yarns, but these new spinning methods There is still no substitute for ring spinning in terms of raw material availability and overall yarn quality. Therefore, ring spinning is still the most important method of spun yarn production. The production of high-quality spun yarn by improving th...
