  • Reinforced cellulosic film
    Patent number: 5603884
    Abstract: Disclosed is a method of preparing an extruded cellulosic film which contains a uniform dispersion of hemp fibers by first adding the fibers to an amine oxide cellulose solvent to form a slurry, mixing the slurry with a molten aqueous solution of cellulose and amine oxide cellulose solvent extruding the mixture end then regenerating the dissolved cellulose.

  • Cellulose food casing manufacturing method
    Patent number: 5451364
    Abstract: In a method for forming a cellulose tube suitable for use as a food casing, in which a solution of nonderivatized cellulose, tertiary amine N-oxide and water is extruded through a die gap and the extruded tube downwardly flowed through an air length while being internally cooled, and passed into a water bath, the tube transverse direction tensile strength is substantially increased by drawing the extruded tube through an air length of at least about six inches.

    Assignee: Viskase Corporation
    Inventors: Paul E. Ducharme, Jr., Edward M. Kajiwara, Norman A. Portnoy
  • Method of making a cellulose food casing
    Patent number: 5277857
    Abstract: A cellulosic food casing formed by extruding a nonderivatized cellulose solution composed of cellulose pulp and an amine solvent into a seamless tube, contacting the inner and outer surfaces of the seamless tube with a nonsolvent liquid to precipitate a tube of nonderivatized cellulose and thereafter contacting the same with a water soluble softener. Apparatus for forming the food casing and a food casing of nonderivatized cellulose also are disclosed.
