Description

A three-color fancy yarn production device and production method

technical field

The invention relates to the technical field of spinning, in particular to a three-color fancy yarn production device and production method.

Background technique

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 color expression, diversified use of raw materials, and creativity. These make fancy yarn products easy to introduce new ones and produce more differentiated textile products. In today's pursuit of personalized consumption In this era, the market has endowed fancy yarn with a broad space. Among them, segment colored yarn is a kind of fancy yarn that is widely researched and applied at present. It has a new style of multi-color combination. It not only has thickness changes in the axial direction of the yarn, but also has fancy colors that appear alternately in discontinuous distribution. Presents irregular and unique flower and color effects. At present, the production of segment colored yarn is mainly carried out on the traditional spinning frame with three rollers. The white roving is continuously fed by the middle roller, and one colored auxiliary yarn is intermittently fed by the rear roller. Segment color effect. This method has lower modification cost and higher efficiency, but the yarn dryness uniformity 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 provided, but this 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.

In view of the above problems, the present invention provides a three-color fancy yarn production device and production method, which adopts four-row rollers driven separately, and has grooves on the rubber rollers, so that the fed rovings of three different colors can be separated into three different colors. Independent drafting in the drafting zone composed of rear roller and front roller, middle rear roller and front roller, middle front roller and front roller, then realizes the production of three-color fancy yarn, enriches the variety of yarns, and improves yarn quality. added value.
