Fibrous paper structures utilizing waterborne shape memory polymers

摘要

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; andc) 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.

1. A fibrous structure, the fibrous structure being a paper product treated with a waterborne shape memory polymer comprising 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 said cross-linkable unit connects said switchable segment to said chargeable unit, wherein said waterborne shape memory polymer is dispersible in water, and wherein said fibrous structure is an absorbent tissue-towel paper product, said tissue towel paper product being treated with about 0.1 to about 15% by weight of dry fibers of said shape memory polymer to have temporary three-dimensional structure.
