ABSTRACT:
An absorbent batt of non-delignified fibers is stabilized by applying a lignin solvent to an assemblage of such fibers to soften at least 10 percent of the fibers. When the fiber assemblage is compressed and the solvent is removed, the softened lignin of adjacent contacting fibers cause a lignin-to-lignin interfiber bond to occur at the fiber intersection.
