Abstract

VAPOR MODIFIED CELLULOSIC FIBERS An improved wet-lay papermaking process is provided which employs substantially modified cellulosic fibers, said fibers being characterized by improved properties, such as reduced swellability and reduced natural fiber-to-fiber bonding. The fibers are produced by a process which comprises treating dry fibers with formaldehyde vapor to react with and internally cross-link the fibers by reacting with the formaldehyde itself and with the fibers. The fibers, when employed as a component of a papermaking furnish, produce improved cellulosic sheet materials which exhibit increased bulk and reduced swellability and dry tensile strength.
