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 invention relates to a method and system for manufacturing a fibrous yarn. An aqueous suspension having fibers and at least one rheology modifier is directed through at least one nozzle to form at least one fibrous yarn. The said nozzle is adapted to swirl the flow of the aqueous suspension around the main flow axis of the said nozzle. Then the aqueous suspension at the exit of the nozzle is merged with at least one annular flow comprising at least one cross linking reagent. Then the fibrous yarn is subjected to pressing mechanism. The pressing mechanism is adapted to dewater and twist the fibrous yarn. Finally, a fibrous yarn product having improved physical properties is produced.
