Method of producing absorbent structures with high wet strength, absorbency, and softness
A method of making an absorbent structure including forming a stock mixture of fibers, a cationic wet strength resin, an anionic polyacrylamide and a cellulase enzyme, and at least partially drying the stock mixture to form a web.
1. An absorbent structure that has a CD wet tensile strength value that is at least 35% of the value of a CD dry tensile strength value of the absorbent structure, the absorbent structure comprising cellulase.
2. The absorbent structure of claim 1 , comprising two or more plies.
3. The absorbent structure of claim 2 , wherein each ply comprises a multi-layer web.
4. The absorbent structure of claim 1 , wherein the absorbent structure is a paper towel product.
5. The absorbent structure of claim 1 , wherein the absorbent structure has a HF softness of at least 46.
6. The absorbent structure of claim 1 , wherein the absorbent structure has a TS750 surface smoothness value of less than 60.
7. A rolled 2-ply through air dried paper towel that has a ratio of CD wet tensile strength to basis weight that is 3.6 or greater, the paper towel comprising cellulase.
8. A rolled 2-ply through air dried paper towel that has a CD wet tensile strength value that is at least 35% of the value of a CD dry tensile strength value of the rolled 2-ply through air dried paper towel, the paper towel comprising cellulase.
