Description

Technical Field

[0001] The utility model relates to the technical field of polyester covered yarn production, in particular to a tensioning wire rack for polyester covered yarn production. Background Art

[0002] Polyester covered yarn is a textile material made by combining polyester filament with other materials through a special process. It usually refers to a PVC (polyvinyl chloride) blend evenly coated on the periphery of high-strength polyester filament to form a PVC / PET (polyethylene terephthalate) composite core-spun yarn. This material combines the advantages of polyester and PVC, has excellent strength and wear resistance, and also has certain flame retardancy. It is widely used in outdoor products such as sunshades and furniture.

[0003] During the production and processing of polyester covered yarn, the tensioning force needs to be adjusted. Some existing tensioning wire racks used for polyester covered yarn production are not convenient for adjusting the tension of the polyester covered yarn according to needs. When the tension is too high, the polyester covered yarn is easily broken, and when the tension is too low, the polyester covered yarn is easily entangled. The device has poor flexibility. Therefore, a tensioning wire rack for polyester covered yarn production is proposed. Utility Model Content
