  • Strengthening compositions and treatments for lignocellulosic materials
    Patent number: 6114471
    Abstract: The strength of lignocellulosic materials is improved by treating them with water-soluble strengthening agents containing sulfonic units, and rendering these agents water-insoluble by reacting them with compounds containing azetidinium rings. Thus, a substantial reduction or elimination of the bleeding of said strengthening agents from the lignocellulosic materials when touched with wet hands or contacted under humid conditions is achieved.
