Description

A multi-channel ring spinning fancy twisting device and interactive asymmetric twisting method

technical field

The invention relates to a multi-channel ring spindle fancy twisting device and an interactive asymmetric twisting method, belonging to the technical field of digital twisting.

Background technique

Ring spinning fancy twister usually adopts two-step method to produce fancy yarn. The first step is to twist the decoration yarn and core yarn with Z twist and form overfeed to the core yarn. By controlling the overfeed amount, different flower patterns can be formed. In the third step, the plied yarn of the fixed thread and the decorated yarn core yarn is twisted twice with S twist to form a fancy thread. The main problems in the production of the fancy thread by existing ring spinning are as follows:

1. Single twisting method

The traditional ring twisting machine twists the two yarns output by the front and rear rollers respectively through ring twisting to form strands. Since the front roller and the rear roller are not on the same axis, one yarn is output from the front roller and directly enters the twisting zone, and the other yarn is output from the rear roller and then turns to the twisting zone through the guide bar. Under the action of the ring twister, the two yarns meet at the twist point and are twisted into a strand.

The difference between the two yarn delivery methods of the core yarn and the decorative yarn determines that the speed of the yarn output by the front roller can be greater than the speed of the yarn sliver output by the rear roller, and the yarn output speed of the rear roller cannot be greater than the yarn output by the front roller. speed. Therefore, the twisted strands are wound onto the spindle through the action of the program traveler, and the linear speed at which the strands are wound onto the spindle is generally equal to the speed at which the back roller outputs the sliver. For this reason, when spinning knot yarn, loop yarn and braided yarn, the yarn output by the front roller is used as the decorative yarn, and the yarn output by the rear roller is used as the core yarn, and the two cannot be switched, so the twisting method is single.

2. The variety of spinning fancy thread is single

Since the core yarn and the decorative yarn cannot be switched when the ring twisting machine is processing the fancy yarn, it is impossible to realize the interactive conversion between the decorative yarn and the core yarn in different twisting methods such as wrapped twist, twist twist, and circle twist. Also can't realize the interactive conversion between present decorated yarn and core yarn in fancy line structures such as wrapping, knot, circle, braid. Because the ring twisting machine is difficult to control the changes in the wrapping structure, shape, color, style and feel of the fancy thread during the spinning process of the fancy thread, it cannot meet the requirements of changing shapes, rich and delicate colors, and flexible styles. The demand for avant-garde fancy line clothing fabrics.
