Abstract

MÉTODO PARA AUMENTAR A RESISTÊNCIA DE UMA FOLHA DE PAPEL. A presente divulgação fornece métodos e composições para reforço de papel. Os métodos podem incluir uma etapa de pulverização de um polímero aniônico em uma folha de papel para aumentar a resistência da folha de papel. O polímero aniônico pode ter grupos amino, grupos amida ou uma combinação de grupos amino e grupos amida. Esses grupos podem ser funcionalizados com um aldeído. Os métodos também podem incluir uma etapa de adição de uma composição de extremidade úmida a uma extremidade úmida do processo de fabricação de papel.
