Device for machining compact siro covering yarns

Abstract

The invention discloses a device for machining compact siro covering yarns. The device comprises a rear roller, a middle roller, a front roller, a yarn traction device, thick yarn shaft tubes and a spandex yarn shaft tube, wherein the yarn traction device is fixed at the lower end of a rack and is connected with the front roller, the middle roller, the rear roller and the thick yarn shaft tubes upwards in sequence through yarns. The device is characterized in that an air sucking tube is further arranged between the front roller and the yarn traction device; the air sucking tube is sleeved by a grid loop; two air sucking grooves are formed in positions corresponding to the grid loop, on the air sucking tube; a buffer shaft is further arranged between a yarn guide roller and the air sucking tube; and under the traction of the yarn traction device, spandex yarns are led downwards to be twisted with yarns on the grid loop through the yarn guide roller and the buffer shaft. By adopting the device, resultant yarn hairiness can be greatly reduced, the strength of the yarns can be improved, an effect of tightening the yarns can be achieved, and a high-quality product can be provided for the high-end denim market.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, in particular to a processing device for compact Siro core-spun yarn. Background technique [0002] In the field of traditional yarn manufacturing, all kinds of fibers are directly spun on the textile machine. At the end of the 20th century, covered yarn appeared. After the spinning frame was transformed, the core-spun yarn was planted with special fibers to form a yarn core, and textile fibers such as cotton and fibers were wound outside the yarn core to form a core-spun yarn. Then it is woven into various elastic or non-elastic fabrics by loom, which is used in the field of clothing. The traditional core-spun yarn device is a production device that twists a roving sliver with fiber filaments in the form of ring spinning. The traditional core-spun yarn Yarn products have the defects that the yarn is not good for covering the filaments, and there is a phenomenon of dew, and there are a...
