Abstract

Fibrous elements, such as filaments, and more particularly to fibrous elements employing a polymer and a wetting agent, methods for making such fibrous elements, fibrous structures employing such fibrous elements, methods for making such fibrous structures and packages containing such fibrous structures are provided.

Claims (8)

1. A paper towel comprising a co-formed fibrous structure, wherein the co-formed fibrous structure comprises from about 30% to 90% by dry weight of the paper towel of a plurality of wood pulp fibers and about 10% to about 70% by dry weight of the paper towel of a plurality of meltblown filaments derived from a polymer composition comprising 100% by weight of the polymer composition of one or more biodegradable, thermoplastic polymers selected from the group consisting of polylactic acid, polyhydroxyalkanoate, polycaprolactone, and mixtures thereof, wherein the paper towel exhibits a contact angle of less than 80° and wherein the plurality of wood pulp fibers are commingled with the plurality of meltblown filaments.

2. The paper towel according to claim 1 wherein the paper towel exhibits a contact angle of less than 75°.

3. The paper towel according to claim 1 wherein the paper towel further comprises a wetting agent, wherein the wetting agent comprises a surfactant.

4. The paper towel according to claim 1 wherein the paper towel further comprises a wetting agent selected from the group consisting of: silicone surfactants, polyethylene glycols, glycols and mixtures thereof.

5. The paper towel according to claim 1 wherein the paper towel further comprises a wetting agent, wherein the wetting agent is a melt additive wetting agent.

6. A package containing a paper towel, wherein the paper towel comprises a co-formed fibrous structure, wherein the co-formed fibrous structure comprises from about 30% to 90% by dry weight of the paper towel of a plurality of wood pulp fibers and about 10% to about 70% by dry weight of the paper towel of a plurality of meltblown filaments derived from a polymer composition comprising 100% by weight of the polymer composition of one or more biodegradable, thermoplastic polymers, wherein the paper towel exhibits a contact angle of less than 80° and wherein the plurality of wood pulp fibers are commingled with the plurality of meltblown filaments.

7. The paper towel according to claim 1 wherein the one or more biodegradable, thermoplastic polymers comprises polylactic acid.

8. The package according to claim 6 wherein the one or more biodegradable, thermoplastic polymers comprises polylactic acid.
