Abstract

602,470. Sizing paper pulp. BURGESS, A. F. (Institute of Paper Chemistry). May 22, 1945, No. 12745. [Class 96] Paper pulp is sized, e.g., in the beater, by adding as a powder or as an aqueous dispersion, mannan and galactan as obtained from seeds of the guar plant, i.e., in approximate proportions 58 :38. Other, usual sizing media may be included. Dilute borax solution, for hardening and increasing wetstrength may be applied just before drying the paper, in which case rosin sizing should be omitted.
