Description

False twister and method of use thereof

Technical Field

The invention belongs to the field of silk thread processing, and particularly relates to a false twister and a use method thereof.

Background

False twisters are widely used in the textile industry. The working principle of the false twister is as follows: because both ends of the yarn are controlled, twisting between both ends of the yarn can produce equal numbers of turns but different directions of twist on the yarn, can increase the strength of the same segment as the yarn is designed to twist, and can simultaneously cause untwisting or reverse twisting of the other segment of the yarn.

Currently, the common false twisters commonly used mainly comprise a rotor type, a friction disc type, a rubber ring type, a rubbing ring friction type and the like.

The existing false twister has the problem of yarn friction, and the yarn at the outlet end often has residual twisting. However, during certain thread processing processes, thread entanglement and friction is not allowed due to the special nature of the threads; also, some processes require twisting of untwisted filaments followed by processing, after which the filaments are required to be completely untwisted and reverse or after-twist is not allowed. Therefore, the conventional false twister cannot meet the above processing requirements.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1, an embodiment of the present invention provides a false twister 1 capable of processing a yarn 2, the false twister 1 includes a support 11 and three rotating wheels 12 mounted thereon and capable of cooperatively tensioning and conveying the yarn 2, the three rotating wheels 12 are respectively rotatable about their axes, and the support 11 is rotatable about its axis 13 and drives the three rotating wheels 12 to revolve synchronously about the axis 13. As shown in fig. 2 and 3, in actual use, the filament 2 sequentially winds around the three rotating wheels 12 to form an inverted omega shape and tension the filament 2, and the filament 2 is twisted and untwisted by the rotation of the three rotating wheels 12 and the revolution around the axis 13. The structure can ensure that the silk thread 2 has no friction damage in the twisting and untwisting processes, can precisely control the twist degree of twisting, and ensures that the untwisted silk thread is completely untwisted.

As a preferred embodiment, the three rotating wheels 12 are a first rotating wheel 121, a second rotating wheel 122 and a third rotating wheel 123 in sequence along the running direction of the silk thread, and the outer common tangent of the rims at one side of the first rotating wheel 121 and the third rotating wheel 123 is coincident with the axis 13. By means of the matching mode, the yarn can be guaranteed to be twisted and untwisted in the false twister 1 along the axis 13, the stability of the yarn processing process is guaranteed, and the yarn quality is improved.

As a preferred embodiment, the tread around which the thread 2 passes on the three wheels 12 is in the same plane to avoid deviation of the thread from the direction of conveyance, ensuring that the thread segments travel on the three wheels 12 in the same longitudinal plane.

Another embodiment of the present invention provides a method for using the above false twister 1, wherein the running mode of the silk thread 2 is as follows: after being guided by the input runner 3, the yarn 2 input from the input end (end a) passes through the process treatment area 4, then enters the false twister 1 from one end of the false twister 1 along the axis 13, and the yarn 2 sequentially winds around the first runner 121, the second runner 122 and the third runner 123 in the false twister 1, is tensioned to form an inverted V shape or an inverted omega shape, and then is output from the other end of the false twister 1 to the output runner 5 and then is output from the output end (end B); the using method specifically comprises the following steps:

pre-twisting: as shown in fig. 2, after one end of the yarn 2 passes out of the false twister 1, the passing-out end of the yarn 2 is temporarily tethered to the bracket 11, and the false twister 1 rotates about the axis 13 for a certain number of turns so that the yarn section between the input pulley 3 and the first pulley 121 generates a predetermined twist while the yarn section after the first pulley 121 is maintained in an untwisted state;

false twisting process: as shown in fig. 3, the end of the yarn 2 is untwisted, the yarn is continuously fed at a predetermined feeding speed according to the advancing direction of the yarn, and the false twister 1 is simultaneously rotated at a predetermined rotation speed to twist and untwist the yarn 2, so that the yarn section before the third rotating wheel 123 is twisted, and the yarn section after the third rotating wheel 123 is in an untwisted state.

The rotating wheels in the embodiment of the invention have the effect of twisting resistance on the silk thread. As shown in fig. 2, during the pre-twisting process, since the threading end of the yarn 2 is tethered to the bracket, the yarn section between the first pulley 121 and the threading end has no twist, while the yarn section between the input pulley 3 and the first pulley 121 generates a predetermined twist due to the rotation of the false twister 1. The original untwisted yarn 2 is subjected to a true twisting operation by pre-twisting, so that the twist of the yarn remains unchanged during the second stage of false twisting.

As shown in fig. 3, in the false twisting process, the yarn 2 is twisted between the input pulley 3 and the first pulley 121 (the twisting direction is defined as positive direction), the twist is kept unchanged by the pre-twisting process, only the yarn is fed between the first pulley 121 and the third pulley 123, the yarn is not twisted nor untwisted, and when the yarn 2 travels to the third pulley 123, the number of twists is cancelled, the twist is zero, and the yarn is output in a completely untwisted state due to the reverse twisting (the twisting direction is defined as negative direction).
