Embodiment Construction

[0012] Raw materials: pure cotton yarn with a basis weight of 5.22g / 10m. Spinning machine: CZJF-5 intelligent multifunctional spinning proofing machine. Spinning process conditions: the pressure (gauge pressure) at the inlet of the swirl nozzle is 0.2MPa, the distance from the swirl nozzle to the front jaw is 9cm, and the swirl nozzle is. The Z-twisted pure cotton spun yarn with a twist coefficient of 360 and a fineness of 30tex was spun 1200m for each sample, and the spindle speed was 12000r / min.

[0013] Yarn properties are tested in accordance with the national standard GB / T7243-1987 "Yarn Hairiness Determination Method Projection Counting Method", national standard GB / T3916-1997 "Determination of breaking strength and elongation at break of a single yarn of textile package yarn" , GB / T3292-1997 "Test Method for Uneven Yarn Dryness of Textile Yarns by Capacitance Method". Table 1 Comparison of properties of ordinary ring spun yarns and yarns installed with swirl nozzles. ...

Abstract

The invention discloses a device for improving the quality of ring-spun yarn by means of a swirl nozzle and belongs to the technical field of textile engineering. The device is called swirl nozzle for short. The swirl nozzle is mainly composed of a yarn path and an air path and is installed on a ring spinning frame and located between a front roller and a yarn guide wire. Airflow enters the yarn path through the air path after being injected in, so that rotational flow is formed to conduct untwisting and re-twisting on hairy yarn, and then hairiness is effectively reduced and the yarn evenness and strength of spun yarn are improved. The device is simple in structure, low in transformation cost, convenient to install and high in development and application value.

Description

technical field [0001] A device for improving the quality of ring spun yarn by using vortex, called a vortex nozzle, the invention belongs to the field of textile machinery, and relates to a new device for improving yarn quality. Background technique [0002] Ring spinning is currently the spinning method with the largest proportion in spinning production, which has the advantages of mature technology, stable yarn quality and good variety adaptability. However, on the ring spinning frame, there is a spinning triangle during the twisting and forming process of the yarn, and the fibers in the sliver in the spinning triangle cannot be completely controlled, and some free fiber ends are exposed because they cannot be involved in the yarn body. Hairiness is formed on the outside. On the other hand, under the action of yarn tension, the centripetal force on the fiber is different, and repeated internal and external transfer occurs in the radial direction of the sliver. During the ...
