Abstract: The application relates to a method and apparatus for manufacturing a natural fiber based staple fibers. The application further relates to the staple fibers, staple fiber based raw wool and products comprising such. A method comprises providing a cellulose suspension (101, 310, 510) including water, refined cellulose fibrils and at least one rheology modifier, directing the cellulose suspension through a nozzle (102, 320, 520) onto a surface (300, 400, 500), drying the cellulose suspension onto the surface (103, 300, 400, 500) for forming a fiber (350, 550), and cutting the cellulose suspension on the surface for forming staple fibers (105).
