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 method for spinning of high-strength yarns. The rotor-spinning method for the spinning of the high-strength yarns is characterized in that the spinning is conducted by a rotor-spinning device which eliminates vortexes. The rotor-spinning device which eliminates the vortexes comprises a fiber conveying channel and a bypass channel connected to an air-supply air pump, wherein center axes of the bypass channel and the fiber conveying channel are located on the same straight line, and the bypass channel is located in the direction opposite to a fiber conveying direction; an entrance of the fiber conveying channel located on one side of a vortex elimination channel is connected to a corresponding gap of a carding roller cover shell by the entrance of the fiber conveying channel, and the other side edge of the vortex elimination channel is straight edge without a gap; and the fiber conveying channel is in arc transition connection with the carding roller cover shell. According to the invention, the carding roller cover shell is in arc connection with the fiber conveying channel, and the bypass channel is used to supply air flows by the air-supply air pump, so the vortexes at the entrance of the fiber conveying channel can be eliminated; harmful fiber forms such as bending, hooking and folding can be reduced; parallel straightness of fibers can be increased; and final yarn strength can be enhanced.

Description

technical field [0001] The invention relates to the textile field, in particular to a rotor spinning method for spinning high-strength yarns. Background technique [0002] As a new spinning technology, rotor spinning has the advantages of short process, high efficiency and labor saving compared with traditional ring spinning. However, for the same yarn with the same count, the strength of rotor-spun yarn is much lower than that of ring-spun yarn. The reason is that in the rotor-spun yarn, the straightness of the fiber is low, the proportion of bent, hooked and folded fibers is large, and the strength of a single fiber is not fully utilized, so the strength of the rotor-spun yarn is relatively low. One of the reasons for the poor fiber morphology in rotor-spun yarn is that the fibers are transported by air during their transfer from the opening roller via the fiber channel to the rotor collector. The structure of the rotor spinning device in the prior art is as figure 1 As...
