False-twisting device and process method for single-spindle disc-type ring spinning

Abstract

The invention discloses a single-spindle disc-type ring spinning false twisting device and technique. The single-spindle disc-type ring spinning false twisting device comprises a rotary disc-type false twisting device body which is installed on a ring spinning frame and a separation rod. A spinning yarn section outputted by front rollers are falsely twisted by adopting two twisting points formed by one rotary disc, and the separation rod is installed between the two false twisting points and plays a role in separating the two false twisting points and increasing the pressure between the spinning yarn section and the selected disc. The twisting degree distribution of the spinning yarn section can be adjusted by controlling the rotation speed of the rotary disc and the output speed of a front roller yarn under the condition of determining the diameter parameter of the rotary disc; and the needed performance of a final yarn can be acquired by adjusting the oscillating angle of the separation rod and adjusting a contact angle of the yarn on the rotary disc. By adopting the single-spindle disc-type ring spinning false twisting device, the size of a spinning twisting triangular area can be reduced, the twisting degree of the yarn in the spinning triangular area can be increased, the strength of fiber beams in the spinning twisting triangular area can be improved, and finally the hairiness of the final yarn can be reduced.

Description

technical field [0001] The present invention relates to spinning technology for the manufacture of ring-spun yarns. The present invention particularly relates to the following device and process method, which utilizes disc-type false-twisting equipment to perform false-twisting on the spinning section of the existing spinning frame, so as to improve the strength, hairiness, twist and other properties of the final yarn. The system has convenient operation performance. Background technique [0002] Twisted yarns have twist instabilities resulting in residual torque. This residual torque of the yarn has an impact on the processing quality of the subsequent product, making the subsequent processing process more difficult. Therefore, such residual torque should be prevented to the greatest extent possible in the spinning industry. [0003] Since the spun yarn is made of fibers through twisting, the residual torque of the yarn is mainly affected by the type of fiber, the shape ...

AI Technical Summary

Problems solved by technology

In the spinning-in process of the above-mentioned devices, the yarn needs to pass through the hole of an additional false twister, which makes spinning-up extremely difficult

In the above-mentioned patent, when installed on the existing spinning equipment, the spatial position and spatial state of the existing spinning section will be changed, causing the encircling arc between the yarn and the front roller to increase, or changing the distance between the yarn and the yarn guide hook. The change of these parameters increases the actual length of the spinning section, which affects the application of the existing mature spinning process theory
