Abstract
A spinning device for forming slub filament yarn in a fully-drawn yarn process comprises a hot roller box, a first hot roller and a second hot roller. At least one of the first hot roller and the second hot roller comprises a heat forming roller. The heat forming roller comprises a cylindrical body part, a heating device arranged on the body part, and a contact layer made of heat conductive material and wrapping the outside of the body part to make contact with filaments. A plurality of heating areas and a plurality of non-heating areas are formed on the contact layer. The heating areas and the non-heating areas extend in the axial direction of the heat forming roller and are alternately arrayed in the circumferential direction. The filaments making contact with the heating areas are heated into a viscoelastic state, the filaments making contact with the non-heating areas are kept in a solidified state, and therefore the filaments are stretched into initial slub filament yarns with thick joint parts and thin joint parts alternately arranged. By forming the lower-temperature areas and the heating areas on the surface of the heat forming roller, the slub filament yarns can be formed, the manufacturing process is simplified, and manufacturing cost is reduced.
