Description

Technical Field

[0001] The present invention relates to the technical field of twisting devices, in particular to a twisting method and a device for ultra-fine nylon stretch yarn. Background Art

[0002] The twisting device for ultrafine nylon stretch yarn usually includes the following parts: Stretch yarn supply system: used to feed pre-treated ultrafine nylon stretch yarn into the twisting machine. This system usually includes a stretch yarn take-up and pay-out device and a tension control device to ensure a stable supply of stretch yarn. Twisting machine: used to twist two or more strands of ultrafine nylon stretch yarn. The twisting machine usually includes two or more twisters and corresponding twisting wheels, as well as the main drive device of the twisting machine. The number and arrangement of twisters and twisting wheels will affect the twisting effect. Pay-off machine: used to place the twisted ultrafine nylon stretch yarn on it for winding and packaging. The pay-off machine usually includes a take-up drum and a tension control device to ensure stable pay-off of the stretch yarn.

[0003] When applying for this invention, the applicant searched and discovered a Chinese patent application numbered "CN201310217047.9" that discloses a "twist adjustment device and method for a rope twisting machine." This patent primarily utilizes a multi-porous disc to even out the angle between rope strands during twisting. The rotatable multi-porous disc evens out the tension on each strand, resulting in a uniform twist as the rope is formed. However, this device requires the placement of new yarn into the twisting device after a roll of yarn has been used, which affects the twisting process. Summary of the Invention
