Claims20
A non-wet-laid layered fibrous structure comprising at least three layers, wherein the fibrous structure comprises:
- a. a first layer comprising a non-thermoplastic first fibrous element comprising a hydroxyl polymer selected from the group consisting of:
- polyvinyl alcohol, polyvinyl alcohol derivatives, and mixtures thereof, wherein the first fibrous element exhibits a length of 10.16 cm or greater and a length to average diameter ratio of greater than 2000, wherein the first fibrous element is a first monocomponent filament;
- b. a second fibrous element different from the first fibrous element, wherein the second fibrous element exhibits a length of less than 5.08 cm, wherein the second fibrous element is a wood pulp fiber;
- and
- c. a third layer comprising a third fibrous element different from the first and second fibrous elements, wherein the third fibrous element comprising a hydroxyl polymer selected from the group consisting of:
- starch, starch derivatives, and mixtures thereof, wherein the third fibrous element exhibits a length of 10.16 cm or greater and a length to average diameter ratio of greater than 2000, wherein the third fibrous element is a second monocomponent filament.
