CA 2096978

ABSTRACT OF THE DISCLOSURE A paper sheet, especially suitable for use as a household paper towel, can be made using a modified wet pressing process by adding a wet strength resin to the papermaking fibers and, after initially forming the wet web, conforming the wet web to the surface contour of a relatively coarse fabric to give the web a textured surface. The web is dried to substantially preserve its texture and thereafter creped. The resulting web has an exceptionally high degree of bulk and absorbency not previously attained by non-throughdried paper products. - 21 -
