Slubby yarn and production method thereof

Abstract

The invention discloses slubby yarn which comprises one part of parallel fiber bundles and one part of bamboo joint fiber bundles with raised bamboo joint sections. The invention further provides a production method of the slubby yarn. In the method, a ring spinning fine yarn machine provided with a slubby yarn device is adopted, wherein the ring spinning fine yarn machine comprises a front roller, a middle roller II, a middle roller I and a rear roller which are sequentially arranged for constituting a four-roller drafting device, and the production method comprises the following steps: inputting roving from the rear roller, and drafting by virtue of the front roller so as to form the bamboo joint fiber bundle; simultaneously drafting another type of fibers between the middle roller II and the front roller, and then forming the parallel fiber bundles; and converging the parallel fiber bundles and the bamboo joint fiber bundles at a front jaw, twisting the two into one yarn through a twisting structure, and outputting. The slubby yarn has the following beneficial effects: 1) the slubby yarn comprises one part of the parallel fiber bundles, thereby having great strength and enabling the slubby yarn to be applicable to being woven into a high-grade fabric; and 2) the four-roller fine yarn machine is adopted for production, the product fluctuation is small, the quality of the slubby yarn is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a slub yarn and a production method thereof, belonging to the technical field of textile processing. Background technique [0002] The traditional ring spinning frame has three rollers and can only spin plain yarn. The roving is input from the rear roller, and the speeds of the rear, middle and front rollers increase accordingly, and the drafting force is generated under the pressure of the pressurizing device to achieve the purpose of drafting and controlling the fiber movement, and the roving is drawn into a quantitative and twist direction. , twist and other plain yarns that meet the design requirements. With the development of technology, after adding bell mouth and other devices, two strands of roving can also be input from the back roller at the same time, that is, siro spinning technology. [0003] The three-roller ring spinning machine can spin slub yarn after installing other devices. Slub yarn is a single yarn with...

AI Technical Summary

Problems solved by technology

This form of slub yarn has the following problems: the twist at the slub section is relatively weak, showing low yarn strength and large strength unevenness; it is inconvenient to change varieties during production, and the product quality fluctuates greatly, often
