Description

Technical Field

[0001] This utility model relates to the field of false twisting technology of polyethylene fibers, and in particular to a false twisting device for bundling polyethylene fibers. Background Technology

[0002] During the processing of polyethylene fibers, a false twister can be used to create a spiral crimp structure in the fibers without changing the net twist, which can be used to manufacture polyethylene elastic yarn.

[0003] The friction disc false twister is one of the main components used for false twisting deformation. The polyethylene fiber bundle passes through the middle of three stacked friction discs, and the outer edge surface of the friction disc directly rubs against the surface of the polyethylene fiber bundle to achieve false twisting.

[0004] Friction discs are usually stacked one on top of the other on a rotating shaft. During rotation, there is a problem of relative sliding between the friction discs and the rotating shaft, making it difficult to ensure synchronization. This results in insufficient friction when the outer edge surface of the friction disc contacts the surface of the polyethylene fiber bundle, affecting the normal false twist effect, which needs to be improved.
