A high-elastic double-core yarn production device and production method

Abstract

The invention provides a high elastic double-core-yarn production device and production method. The device comprises a rear traction roller pair composed of a rear roller and a rear rubber roller, a middle roller pair composed of a middle roller and a middle rubber roller and a front roller pair composed of a front roller and a front rubber roller, wherein feeding rollers are additionally installed at the upper parts of all rubber rollers, and are in connection transmission through gears, the front feeding roller is in tight pressing contact transmission with the front rubber roller, the middle feeding roller is provided with a groove, one chinlon filament is pressed by the rear feeding roller, afterwards passes through the groove of the middle feeding roller and then is pressed and output by the front feeding roller, the other spandex filament is pressed by the middle feeding roller and then is pressed and output by the front feeding roller, and then the chinlon filament and the spandex filament are delivered into a tong opening of the front roller to be converged with a pure cotton fiber strand obtained after traction. Therefore, synchronous feeding of the core filaments and the fiber strand and independent adjustment of the feeding tension of the two core filaments are achieved, and further the production of the high elastic double-core-yarn with an excellent core filament covering effect is achieved.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a high-elastic double-core yarn production device and production method. Background technique [0002] With the continuous advancement of the times, people's requirements for clothing materials continue to increase. At present, the textile and clothing industry is in an era of pursuing fashion, diversification and high quality. Therefore, new requirements have been put forward for the development of textile raw materials, among which fancy yarns have gradually entered people's field of vision and occupy an irreplaceable position. Fancy yarn refers to the yarn with special structure and appearance effect obtained by processing fiber or yarn with special raw materials, special equipment or special technology in the process of spinning and thread making. It is a decorative yarn in yarn products. A kind of yarn that works. Fancy yarn has unique structure, flexible shape, rich colo...

Problems solved by technology

The modification cost of this method is lower and the efficiency is higher, but the evenness of yarn dryness is poor

In view of this, in the Chinese patent "Segment Color Spinning Transmission Device (Patent No.: ZL200420081737.2)", a segment color yarn production device with four loops is given, but the device still uses double roving feeding, and at the same time , the first roller and the second roller are still controlled by the same motor, so the main draft cannot be adjusted freely
