  • Casing paper having alkali resistance
    Patent number: 4222821
    Abstract: Fibrous casing paper is treated with viscose, a polyamide-epihalohydrin resin and cationic polyethylene imine resin to provide a synergistic improvement in the alkaline wet tensile strength while maintaining satisfactory viscose absorbency.
    Type: Grant
    Filed: September 29, 1978
    Date of Patent: September 16, 1980
    Assignee: C. H. Dexter Limited
    Inventors: Newlyn Jones, Alistair C. Stewart, Colin Elston
  • Paper having good absorbency and alkali resistance and method of making said paper
    Patent number: 4218286
    Abstract: Fibrous paper webs of high water absorbency and improved alkaline wet tensile strength are obtained by treating the fibers prior to web formation or subsequent to web formation with aqueous solutions of a water-soluble thermosetting reaction product of a polyamide and an epichlorohydrin, a water-soluble nonviscose film-forming material such as hydroxy ethyl cellulose and a water-soluble polyethylene imine. The resultant absorbent sheet material maintains its absorbency upon aging, exhibits high wet caustic strength and can be used in the manufacture of tea bags or food casings.
