Splitting twisting-boosting type vortex spinner

Abstract

The invention belongs to the technical field of textile processing and relates to a splitting twisting-boosting type vortex spinner which is used for feeding fiber bundles into a vortex spinning area on a spinning machine in a splitting manner and boosts twisting for the fiber bundles in vortex spinning. The splitting twisting-boosting type vortex spinner is of a structure with a splitting feeding channel and a twisting-boosting device, a structure of a traditional vortex spinner with a single feeding channel and a single static spindle is improved, a vortex spinning mode of single-channel fiber feeding and static spindle pure vortex twisting of the traditional vortex spinner is changed, active holding type twisting is carried out for fiber bundles in the splitting channel, boosted twisting is carried out for fiber bundles guided in by the outer wall of a guide needle during vortex wrapping and winding, fiber control during vortex spinning is enhanced, requirement limit on number of fibers included in a fiber bundle and cohesive force during traditional vortex spinning is broken through, spinnable fiber variety and spinnable yarn count range of the vortex spinning technology are expanded. The splitting twisting-boosting type vortex spinner is reasonable in structure and convenient to use and operate.

Description

technical field [0001] The invention relates to a beam-splitting twist-assisted vortex spinning device that feeds fiber strands into bundles into the vortex yarn forming area on a vortex spinning machine, and at the same time assists in twisting the fiber strands in the vortex yarn formation. It belongs to the technical field of textile processing. technical background [0002] The traditional ring spinning method is to actively hold the end spinning, because of the disadvantages of long spinning process, low and limited spinning speed and package capacity, and low degree of automation, so many new non-free end high-speed spinning Methods continue to emerge, such as rotor spinning, friction spinning and vortex spinning. Among them, vortex spinning is a new spinning method that uses a fixed vortex spinning tube to replace a high-speed rotating spinning cup, spinning spindle, and traveler for spinning. The idea of ​​using air-flow spinning was first proposed by DuPont in 195...

Chinese Patent Publication No. CN2835273, publication date 2006.11.08, the name of the invention is a new air-jet vortex spinning nozzle device. The application provides a new type of air-jet vortex spinning nozzle device. Control the airflow power, reduce the unevenness of fiber breakage, and improve the quality of fiber yarn to a certain extent; however, the application still cannot solve the problem of spinning high-count yarns of short fibers by eddy current spinning machines

Chinese Patent Publication No. CN102108574, publication date 2012.04.25, the invention name is a method for producing hemp yarn by vortex spinning. This application case provides a method for producing hemp yarn by vortex spinning for the problem that hemp yarn cannot meet the requirements of high-count and high-density fabrics. The method is to improve the spinnability of ramie fiber by performing a series of pretreatments on the hemp fiber in the process before eddy current spinning, and then use the prepared ramie fiber raw material for conventional eddy current spinning, which improves the hemp fiber to a certain extent. The quality of the eddy current yarn and the spinnable count of the hemp fiber are improved; however, this method involves multiple pre-spinning processes such as the plucking machine, the mixing opener, the vibrating cotton box, the lapping machine, and the carding machine, resulting in the use of The production process of high-quality ramie fiber for eddy current spinning is too long and the cost is too high, which is not conducive to large-scale promotion and use

Chinese Patent Publication No. CN102691143A, publication date 2012.09.26, the name of the invention is a method for improving the yarn-forming performance of vortex spinning. The vortex spinning fiber strands are subjected to segmental heat and humidity softening treatment, and the spinning method that instantly reduces the fiber stiffness greatly improves the fiber's easy control, easy torsion and twisting performance, and effectively improves the vortex spinning yarn performance

However, the method of improving fiber vortex spinning yarn performance by greatly improving fiber performance cannot change the structural characteristics of vortex spun yarns. Therefore, the produced vortex yarn structure still has insufficient fiber internal and external transfer and poor fiber cohesion. , The yarn structure is fluffy, and the mechanical and mechanical properties of the yarn still cannot be fundamentally improved
