METHOD AND APPARATUS FOR MANUFACTURING A STAPLE FIBER BASED ON NATURAL PROTEIN FIBER, A RAW WOOL BASED ON THE STAPLE FIBER, A FIBROUS YARN MADE OF THE STAPLE FIBER, A NON-WOVEN MATERIAL MADE OF THE STAPLE FIBER AND AN ITEM COMPRISING THE STAPLE FIBER

摘要

A method for manufacturing a staple fiber based on natural protein fiber, the method comprising the steps of: - providing a protein suspension, - the protein suspension comprising fibrils of said natural protein fiber, - directing the protein suspension through a nozzle (520) onto a surface (500), - drying the protein suspension on the surface for forming a protein based fiber, - extracting the fiber from the surface and providing the staple fiber.
