Abstract
Disclosed herein is a process for repulping or reclaiming fibers from latex-impregnated materials such as latex impregnated papers. The process involves treating the latex-impregnated material with an alkali solution for a sufficient period of time to separate the latex polymer from the fibers. This is followed by a washing step to rinse away the latex polymer thereby leaving the reclaimed fibers for subsequent use such as the formation of new paper stock.
