Description

Strand twisting device for winding and strand processing method

technical field

The invention relates to a strand twisting device for winding and a strand processing method, in particular to a twisting device for multiple parallel yarns for winding and a strand processing method using the same.

technical background

Ply yarn is a thread formed by twisting two or more single yarns. Its strength and wear resistance are better than that of single yarn. , such as double-strand, triple-strand, and multi-strand. It is mainly used for sewing thread, braiding thread or other yarns for woven and knitted fabrics. The usual processing flow of strands is: bobbin (single yarn)→winding→doubling→twisting→winding→strands, and finally a strand product of a certain specification is formed. Since there are four processes from bobbin to ply, the processing process is long, resulting in relatively high cost.

Therefore, how to reduce the production process of strands is the direction that textile workers have been working on. Sirospun spinning technology, Sirofil spinning technology, and Solospun spinning technology all hope to directly generate strands similar to strands through the transformation of the spinning frame. Yarns with thread structure, but these technologies cannot completely replace the yarn processing and manufacturing process so far.

Contents of the invention

The technical problem to be solved by the present invention is to provide a strand twisting device for winding and a strand processing method to solve the defects in the prior art.

The object of the present invention is at first to provide a strand twisting device for winding, which device is a nozzle capable of forming a vortex field, including a housing, a suction port, an injection hole, an air chamber, an air inlet pipe, a yarn path and a diffusion port, Wherein the injection hole and the inner wall of the yarn path are arranged tangentially, the angle range of the tangential angle β is 0°～10°, 2～6 injection holes are arranged in the same plane, and the diameter of the injection hole is 0.2mm～0.5mm, The spray angle α ranges from 45° to 90°, and the diameter of the suction port is 2mm to 8mm.

In addition, the device is also provided with a yarn connecting port, which is arranged in parallel with the injection hole, and the width d is 0.2 mm to 0.4 mm.

The present invention also provides a method for strand processing using the above-mentioned device, the method comprising the steps of:

Install the device on the winding machine, and form a high-speed flow field in the inner cavity of the device;

Feed the yarn parallel to the device and that's it.

The specific steps and principle are: install the nozzle on the winding machine, use compressed air to enter the air chamber from the intake pipe, and distribute it to each injection hole through the air chamber. In the high-speed flow field of more than 100,000 revolutions, when 2 to 6 bobbins enter the inner cavity of the nozzle in parallel, the hairiness on the outside of each yarn is entangled and covered with each other under the drive of the vortex airflow, thus forming a unique strand The structure realizes the one-time forming process from bobbin to strand.

When the single yarn breaks, it can be spliced and enter the nozzle through the splicing port.

This device can also work in another way. The processing of the strands remains unchanged according to the traditional process of bobbin-winding-doubling-twisting. The difference is that the twisting only adds a lower twist to the strands to ensure The strands can go to the winding machine normally, and then install the nozzle on the winding machine, and the twisted strands pass through the nozzles, and the hairiness outside the strands is entangled and covered with each other under the drive of the vortex airflow, thus forming a unique Structure. Since the strands are already twisted, there is no single yarn breakage, so the nozzle does not require a splicing opening.

In the present invention, an air-jet vortex nozzle is installed on the winder to form strands with a unique structure through the hairiness of the yarn itself, so that the bobbins directly become strands after the winding process, that is: bobbin (single yarn)→( In addition, the air-jet vortex nozzle) winding→strand of the present invention greatly shortens the whole strand manufacturing process, the process is simple, and has greater market economic value.
