Problems solved by technology

Since this kind of fiber is sucked by the negative pressure eddy current field, some fibers will be sucked away from the exhaust port 7 by the air flow during the processing, which seriously affects the uneven thickness of the yarn and the production rate of the product, and also affects the quality of the yarn.

Embodiment Construction

[0017] The present invention installs a newly conceived air-jet vortex spinning compound twister between the drafting zone and the winding zone of the spinning machine. The air-jet vortex spinning compound twister is composed of an upper twister and a lower twister. It uses a positive pressure airflow to generate a vortex field and a pipeline flow, and the fibers enter the vortex field through a conveying pipeline. The fiber strands rotate with the high-speed rotating air flow. While the fiber strands are rotating at high speed, the pipeline flow protects and guides the fiber strands being twisted to leave the eddy current field quickly. During this process, the fiber strands are twisted and produced at high speed. twist the yarn. Such as figure 1 As shown, the upper twister generates a positive pressure vortex field through the positive pressure airflow generated by the compressor, and the negative pressure in the center of the vortex field sucks the fiber flow and drives th...

Abstract

The complex twisting device for air-jet eddyc-current spining to twist fiber strand consists of the upper twisting unit and the lowr twisting unit. Positive pressure air flow is utilized to produce eddy-current field and pipe flow and the fiber is fed to the eddy-current field via the conveying pipe. Fiber strand rotates with the high-speed rotating air flow while the pipe flow protects and guides the twisted fiber strand to leave from the eddy-current field. During the process, fiber strand is twisted to produce twisted yarn in high speed. The present invention makes it possible to produce high-quality yarn at low cost and high speed.

Description

Technical field: [0001] The invention belongs to the textile field, and relates to an air-jet vortex spinning compound twister. Background technique: [0002] The existing vortex spinning is a negative pressure air twisting spinning technology, such as figure 1 As shown, it draws air through the exhaust port 7, the air flow enters from the air inlet 1, and the air flow entering the vortex tube 15 forms a negative pressure vortex 16, and the negative pressure vortex field sucks the fiber from the fiber inlet 5, and the rotating vortex The input fiber is twisted by the field, and the twisted yarn is output from the upper end from the yarn drawing tube 17 through the yarn outlet 14 . Since this kind of fiber is sucked by the negative pressure eddy current field, some fibers will be sucked away from the exhaust port 7 by the air flow during the processing, which seriously affects the uneven thickness of the yarn and the production rate of the product, and also affects the quali...
