Problems solved by technology

When the fiber moves to the vortex, it is easy to be involved in the vortex, resulting in fiber bending and entanglement, and even multiple fibers may be involved in the vortex at the same time, forming fiber knots, deteriorating the fiber shape, increasing yarn knots, In the end, the fiber arrangement in the yarn is poor and the strength is reduced

Abstract

The invention relates to a rotor spinning apparatus capable of eliminating eddy current. The rotor spinning apparatus capable of eliminating eddy current comprises an eddy current eliminating channel, wherein the eddy current eliminating channel comprises a fiber conveying channel and a bypass channel connected with an air supplementing pump; the axes of the bypass channel and the fiber conveying channel are positioned on the same straight line, and the bypass channel is positioned in the opposite direction of the fiber conveying direction in the fiber conveying channel; a fiber conveying channel inlet through which the fiber conveying channel is separated from the bypass channel is formed in one side of the eddy current eliminating channel; the eddy current eliminating channel is connected with a corresponding notch of a combing roller housing through the fiber conveying channel inlet, so that the bypass channel connected with the air supplementing pump is communicated with a rotor of the rotor spinning apparatus; the other side of the eddy current eliminating channel is a notch-free straight side; and pressure P of the air supplementing pump and negative pressure Pin in the rotor meet a numerical relationship of P=-37.33-0.0449Pin, wherein the unit of P and Pin is Pa.

Description

Technical field [0001] The invention relates to the textile field, in particular to a rotor spinning device capable of eliminating eddy currents. Background technique [0002] Rotor spinning is a new type of spinning technology, which has the advantages of short flow, high efficiency and labor saving. However, compared with the traditional ring-spun yarn, the strength of the rotor yarn is relatively low. This is due to the poor fiber arrangement in the rotor yarn and the large number of bent and hooked fibers. In the rotor spinning process, after the fiber sliver is combed into single fibers by the saw teeth of the opening roller, the fiber is stripped from the saw teeth of the opening roller by air flow and transported to the rotor cohesion groove to complete spinning. The air flow characteristics in this part of the space from the stripping zone of the opening roller to the fiber conveying channel are the key to affecting the fiber morphology. Poor air flow will deteriorate t...
