摘要： Disclosed embodiments describe a method for manufacturing a staple fiber based on natural protein fiber. The method may include: providing a protein suspension, the protein suspension comprising fibrils of the natural protein fiber; directing the protein suspension through a nozzle onto a surface for forming a protein based fiber; drying the protein suspension on the surface; extracting the fiber from the surface; and providing the staple fiber. Disclosed embodiments may further describe a fiber based raw wool. The raw wool may include staple fibers, wherein the staple fibers are reconstructed on the basis of protein fibrils and are mechanically subdivided from natural protein fibers, wherein the protein fibrils are interlocked by hydrogen bonds, and wherein the raw wool comprises an unoriented, entangled, fluffy network of staple fibers.

摘要： 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).
