ABSTRACT:
Absorbent paper products, such as towels, absorbent wipes, toilet tissue, facial tissue and the like fibrous webs of relatively high bulk, are produced by a method comprising the steps of treating hydrophilic cellulosie fibers to impart kinks, curls, bends, twists, to the fibers; dispersing the treated fibers in an aqueous forming medium, and wet-forming a stratified single-ply web constituted of at least one stratum of the treated fibers and at least one stratum of conventional paper-making fibers. The treating step may consist of wet or dry mechanical working, chemical treatment or a combination of mechanical and chemical treatments. The web forming step comprises preparing a first aqueous furnish of the treated fibers, preparing a second aqueous furnish of the conventional fibers, and concurrently depositing the two furnishes in contiguous layers on a moving foraminous support.
