Abstract

20,548. Helbrouner, A., and Vallee, E. A. Sept. 26, 1905, [date applied for under Patents Act, 1901]. Size; finishes for fabrics and the like.-Plastic .substances &c. can be produced from the transformation product obtained by digesting ossein in caustic alkali solutions, for example caustic soda. The product is soluble in cold water, and may be dissolved in any liquid suitable for the process, for example acetic acid or alkali (caustic or carbonated) solutions and ammoniacal solutions of metallic oxides (copper or nickel), and may be precipitated or coagulated by means of certain mineral or organic products, for example sulphate of ammonia, zinc chloride, copper sulphate, alkali persulphates, sodium chloride, alcohol, &c. The solution in caustic soda will take up cellulose.
