Embodiment Construction

[0106] figure 1 Illustrated is a method for producing natural fiber based raw wool, according to one embodiment. At 101, a protein suspension is provided. The protein suspension comprises an aqueous suspension of mechanically separated protein fibrils. In other words, the protein fibrils themselves were considered natural fibrils. The protein suspension may comprise water, isolated protein fibrils and at least one rheology modifier. The fibrils of the protein suspension may be derived from mechanically shortened protein fibers. In a preferred embodiment of the invention, the protein fibrils are collagen fibrils derived from tanned pelt-based material. Thus, collagen fibrils may be derived, for example, from wetblue hides, i.e., pelts that have been tanned, and where the collagen fibers used as the basis for reconstituted collagen-based fibrils have been tanned according to conventional and well-known methods, (e.g., pretreated by chromium salts).

Abstract

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.

Description

technical field [0001] The present application relates to a method for producing staple fibers based on natural protein fibers, an apparatus for producing staple fibers, raw wool comprising staple fibers based on natural protein fibers, fibrous yarns, and Surfaces used in equipment for the manufacture of staple fibers. Background technique [0002] Products like yarns and fabrics can be made from natural or synthetic starting materials. Synthetic starting materials may negatively impact product recyclability or disposal stages. [0003] Another challenge associated with such materials is that synthetic starting materials are very attractive in terms of pricing, but are often viewed as inferior in terms of desired properties compared to natural fiber based applications. [0004] Natural starting materials may also have negative environmental impacts during their growth or processing. An example of such a natural starting material is cotton.
