Abstract: A fibrous structure. The fibrous structure can be a paper product treated with a waterborne shape memory polymer. The waterborne shape memory polymer can include structural units, wherein each structural unit comprises: a) a switching segment comprising a semicrystalline or amorphous polymer; b) a chargeable unit comprising a cationically or anionically chargeable group; and c) a cross-linkable unit comprising a monomer, wherein the cross-linkable unit connects the switchable segment to the chargeable unit, wherein the waterborne shape memory polymer is dispersible in water.

Abstract: The invention relates to the making of a cellulosic fibrous structure by adding a waterborne shape memory polymer to cellulosic papermaking slurry and forming a web from the waterborne shape memory polymer containing slurry. The web can be optionally foreshortened.

Abstract: A method for making fibrous structures. The method includes the steps of: (a) providing a fibrous furnish comprising papermaking fibers, the fibrous furnish containing, in addition to water and cellulosic fibers, from about 0.1% to about 15% waterborne shape memory polymer; (b) depositing the fibrous furnish onto a foraminous member such that an embryonic fibrous web is formed; (c) associating the embryonic web with a molding member comprising discrete deflection cells or substantially continuous deflection conduits; (d) deflecting the fibers in the embryonic fibrous web into the discrete deflection cells or substantially continuous deflection conduit and removing water from the embryonic web through the discrete deflection cells or substantially continuous deflection conduit so as to form an intermediate fibrous web; (e) optionally, drying the intermediate fibrous web; and (f) optionally, foreshortening the intermediate fibrous web.
