PULPING OF WET STRENGTH BROKE CONTAINING POLYVINYLAMIDE-GLYOXAL RESIN

摘要

Wet strength paper broke composed of fibers bonded together by a wet strength polyvinylamide-glyoxal resin in thermoset state is pulped by contacting the broke with an aqueous medium substantially free from oxidizing agent having a pH between 5 and 10 and a temperature above 100 DEG F. and subjecting the broke to mechanical pulping.
