Problems solved by technology

The processing method omits the dot making process, and realizes the spiral wrapping distribution of the silk segments on the main body of the yarn, but the three-dimensional effect of the yarn is insufficient, and the silk segments are disordered on the main body of the yarn. distributed

Embodiment 1

[0020] After the processes of blending, blending, blowing, carding, and drawing, the fiber strands are fed from the bell mouth and enter the four-roller drafting area, where they are drawn and broken at the middle roller with the warp spun yarn feeding device. The spun yarns are combined to complete the subsequent drafting and enter the twisting chamber together. The spun yarn segments are wrapped around the main structure of the yarn under the action of high-speed rotating airflow to form an air-jet vortex spun yarn with a fancy appearance.

[0021] The four-roller drafting area includes rear rollers, middle and rear rollers, middle rollers and front rollers, the total drafting multiple is 215 times, the main drafting multiple is 32 times, the rear drafting multiple is 3 times, and the upper roller spacing is 45mm, the bottom roller gauge is 39mm, and the feed ratio is 0.99.

[0022] The spun yarn feeding point is the middle roller, and the middle roller-front roller is the d...

Abstract

The invention provides a preparation method of jet vortex spun colored spun yarns capable of controlling and adjusting distribution of discrete points, which comprises the following steps of: additionally arranging a spun yarn feeding device above a four-roller drafting area of a fiber strand, and controlling spun yarns to be fed into a middle roller to finish equipment transformation; controllable adjustment of discrete points on the jet vortex spinning colored spun yarn is achieved by controlling changes of spun yarn density and twist. The method solves the ubiquitous problem of disordered distribution of neps in nep yarns, improves the added value of products, expands the development varieties of fancy yarns and jet vortex spinning colored spun yarns, has the characteristics of simple modification method, low cost, high yarn quality and the like, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of air-jet vortex spinning colored yarns capable of controllably adjusting the distribution of discrete dots. Background technique [0002] The color spun yarn is a new type of yarn, which is wrapped with scattered fiber clusters on the main body of the colored spun yarn. It is mainly through the direct mixing of colored fiber ideas (made by rubbing the modified carding machine) and ordinary colored fibers in the blowing process or the way that colored idea strips and ordinary colored spinning slivers are combined on the drawing frame to realize the fiber. The distribution of ideas on the main body of the yarn has problems such as a long point-making process, the mixing effect is affected by multiple factors, and the distribution of ideas is uncontrollable. [0003] Air-jet vortex spinning color-spun yarn is an important direction for the develo...
