Description

Technical Field

[0001] This utility model relates to the field of polyester filament processing, specifically a stretching device for elastic polyester filament. Background Technology

[0002] Elastic polyester filament is a type of elastic filament produced from polyester. Polyester is a synthetic fiber, primarily made from polyethylene terephthalate (PET) obtained through esterification or transesterification and polycondensation reactions of terephthalic acid or dimethyl terephthalate and ethylene glycol. This PET is then spun and post-treated to form fibers. A stretching device is required during the processing of elastic polyester filament.

[0003] The existing technology has the following problems:

[0004] Most existing elastic polyester yarn stretching devices are not convenient for tension adjustment during use, which can easily cause the polyester yarn to break and become tangled when it is too tight or too loose, thus reducing the overall processing efficiency and affecting its use.
