摘要
Melamine or ammeline is added to wood or wood pulp so that paper produced therefrom has wet and dry strength, ink and pigment retention, improved color and brightness, soil and grease resistance, and electrical properties. The melamine may be added during bleaching of pulp, or during refining in a thermomechanical pulping process, or during beating of a pulp, which may be derived from waste paper. Salts thereof may also be used.
