Description

Technical Field

[0001] The utility model relates to the technical field of composite fiber production, in particular to a spinning device for producing multi-layer composite short fibers. Background Art

[0002] Composite fiber is a type of multi-component fiber, which is a term for artificial fiber varieties. The presence of two or more unmixed polymer fibers on the same fiber cross section is called composite fiber. Sheath-core composite fiber is a more common composite fiber. Spinning equipment is used in the production process of composite fiber.
