Air-jet vortex polyester yarn spinning device

Abstract

The invention discloses an air-jet vortex polyester yarn spinning device. The air-jet vortex polyester yarn spinning device comprises a raw material supply device (1), wherein the raw material supply device (1) is connected with a yarn drafting device (2); the yarn drafting device (2) is connected with a yarn twisting device (3); the yarn twisting device (3) is connected with a finished-product winding device (4); the yarn twisting device (3) comprises a shell body (31); the shell body (31) is internally provided with a first nozzle (32); the first nozzle (32) is connected with a second nozzle (33); the first nozzle (32) comprises a first splitting pipe (321); a plurality of grooves (322) with a spiral structure are uniformly formed in an inner wall of the first splitting pipe (321). The air-jet vortex polyester yarn spinning device has the characteristics of increasing the crossing depth between yarns, improving the twisting uniformity of the yarns, improving the twisting strength and improving the spinning quality.

Description

technical field [0001] The invention relates to a textile machine, in particular to an air-jet vortex spinning polyester yarn device. Background technique [0002] The textile methods of polyester yarn generally include ring spinning, compact spinning ring spinning, air-jet spinning and rotor spinning. The surface of traditional ring spinning is disordered under the same twist condition, and a large number of fiber ends are not Twisted into the yarn body, single fiber protrudes outside the yarn body; the fiber arrangement on the rotor yarn is disordered, the fibers in the middle of the yarn show no clear spiral in the E direction and the S direction, and the fibers are straight. The advantage of air-jet spinning is that the spinning speed is not limited by the spinning linear density, the strength is lower than that of ring-spun yarn, and the CV value of evenness, coarse details, and yarn defects are better than that of ring-spun yarn. Therefore, in order to obtain better qu...

AI Technical Summary

Problems solved by technology

However, the quality of air-jet spinning depends on the adjustment of various parameters of the nozzle. Different yarns need to choose different nozzle parameters due to their different diameters. Due to the differences in nozzle parameters, existing polyester yarns on the market have The intersection depth between the yarns is small, the twisting between the yarns is uneven, etc., and because of the single nozzle structure, the twisting strength is not very large

Therefore, the existing technology has problems such as insufficient crossing depth between yarns, uneven twisting between yarns, low yarn twisting strength and poor spinning quality.
