Abstract: PROBLEM TO BE SOLVED: To provide a protein thin film and a protein fiber manufactured from S-sulfonated keratin derivatives, and to provide a method of manufacturing the protein thin film and the protein fiber. SOLUTION: The method of manufacturing the protein thin film by performing solvent casting of an solution of S-sulfonated keratin protein, and the method of manufacturing the protein fiber by extruding a solution of S-sulfonated keratin into an aqueous solution containing a reductant and salts that causes the protein in the solution to become insoluble are provided. Further, the protein thin film and protein fiber manufactured by the method of manufacturing the protein thin film and protein fiber are also provided. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: A process for the preparation of soluble proteins of high molecular weight with little or no damage to the structural integrity of the proteins. The process is economically and environmentally acceptable by virtue of the cost of reagents that are used, and the recycling of some of those reagents, and is suitable for the production of soluble proteins on a large scale. The proces s includes a first stage using oxidative sulfitolysis followed by a second sta ge using mild conditions to extract the soluble protein. In the case of wool as the protein source the process leads to the production of soluble keratin proteins fractionated into the classes S-sulfonated keratin intermediate filament proteins and S-sulfontated keratin high sulfur proteins.

Abstract: Disclosed is a process for the preparation of keratin derivatives of high molecular weight, the process comprising a first stage digestion step of sulfonating a keratin source by oxidation sulfitolysis followed by a second stage repetitive aqueous extraction involving separation of soluble and insoluble keratin and subsequent re-extraction of the insoluble keratin to thereby produce a highly S-sulfonated keratin derivative.

Abstract: Film, fibre, foam and adhesive materials are produced from soluble S- sulfonated keratins. Once formed, the films, fibres, foams or adhesives are treated to modify the properties of the materials, in particular to improve the wet strength of the materials. Treatments used include removal of the S- sulfonate group by treatment with a reducing agent, treatment with an acid o r treatment with a common protein crosslinking agent or treatment with a reduc ed form of keratin or keratin protein. The films are made by solvent casting a solution of S-sulfonated keratin proteins, the foam made by freeze-drying a solution of S-sulfonated keratin proteins and the fibres made by extruding a solution of a S-sulfonated keratin protein.
