Abstract
Fibrous webs of improved bulk and softness are produced by subjecting hydrophilic papermaking fibers to mechanical deformation, e.g. hammermilling, sufficient to deform the fibers without substantial fiber breakage, dispersing the resulting curled or kinked fibers, preferably in admixture with conventional papermaking fibers, in an aqueous foam with minimal agitation and holding time and forming a wet laid web from the resulting fiber furnish.
