Abstract
Proteins are treated with a fatty substance of animal or vegetable origin emulsified in an aqueous solution of urea, thiourea or a water-soluble substitution product of urea, and are subsequently wet-spun and hardened with an aldehyde such as formaldehyde. The amount of urea or urea derivative used for the treatment is insufficient to dissolve the protein or break the micellar linkages of the protein molecule. It is stated that the urea or urea derivative and the fatty substance become absorbed in the protein molecule and form a stable addition product therein. The fatty substance may be a glyceride or a free fatty acid, either saturated or unsaturated, and it may be one of those used in the process described in Specification 723,215. Preferred fatty substances are oils of fish or sea animal origin containing acids having at least four double bonds, such as whale oil. Drying oils containing acids having at least two double bonds also may be used. The protein may be phosphoprotein, globulin or prolamine (casein from milk) or one derived from peanuts, maize, cottonseed or soya beans. After treatment according to the invention, the protein may be dried and stored before being spun. The spinning baths may be aqueous solutions containing sulphuric acid and sodium sulphate, with addition of glucose or aluminium salts if desired. On leaving the spinning bath, the filaments may undergo known washing treatments in saline baths or treatment in pickling baths as described in Specification 719,319. In the examples, lactic casein is treated with whale oil emulsified in aqueous urea. Sodium hydroxide is used to dissolve the protein. The order in which the reagents are added is varied, and the water used is sometimes permutited water. In example 10, lactic casein is treated with an emulsion of whale oil in aqueous urea but no sodium hydroxide is added. After treatment, the casin is removed, dried and stored. After a month, it is dissolved in concentrated aqueous urea as solvent and spun in known manner and the filaments are washed and hardened with formaldehyde. Specification 723,214 also is referred to.
