Abstract

Compacted fibrous structure articles and methods for making the same are provided.

First claim

What is claimed is:

1 . A compacted fibrous structure article comprising a fibrous structure article such that the compacted fibrous structure article exhibits an Average Overall Density of less than 0.65 g/cm 3 as measured according to the μCT Compacted/Compressed Fibrous Structure Article Test Method.

2 . The compacted fibrous structure article according to claim 1 wherein the compacted fibrous structure article exhibits a first portion exhibiting a first density value and a second portion exhibiting a second density value such that a minimum difference between the first density value and the second density value is at least 1% as measured according to the μCT Compacted/Compressed Fibrous Structure Article Test Method.

3 . The compacted fibrous structure article according to claim 1 wherein the fibrous structure article comprises a nonwoven fibrous structure.

4 . The compacted fibrous structure article according to claim 1 wherein the fibrous structure article comprises a plurality of fibrous elements.

5 . The compacted fibrous structure article according to claim 4 wherein the plurality of fibrous elements comprise a plurality of fibers.

6 . The compacted fibrous structure article according to claim 5 wherein the plurality of fibers comprise a plurality of pulp fibers.

7 . The compacted fibrous structure article according to claim 6 wherein the plurality of pulp fibers comprise a plurality of wood pulp fibers.

8 . The compacted fibrous structure article according to claim 1 wherein the fibrous structure article comprises a wet-laid fibrous structure.

9 . The compacted fibrous structure article according to claim 8 wherein the wet-laid fibrous structure comprises a structured fibrous structure.

10 . The compacted fibrous structure article according to claim 9 wherein the structured fibrous structure comprises a through-air-dried fibrous structure.

11 . The compacted fibrous structure article according to claim 10 wherein the through-air-dried fibrous structure comprises a creped through-air-dried fibrous structure.

12 . The compacted fibrous structure article according to claim 10 wherein the through-air-dried fibrous structure comprises an uncreped through-air-dried fibrous structure.

13 . The compacted fibrous structure article according to claim 8 wherein the structured fibrous structure comprises an ATMOS fibrous structure.

14 . The compacted fibrous structure article according to claim 8 wherein the structured fibrous structure comprises an NTT fibrous structure.

15 . The compacted fibrous structure article according to claim 8 wherein the structured fibrous structure comprises a belt creped fibrous structure.

16 . The compacted fibrous structure article according to claim 8 wherein the structured fibrous structure comprises a fabric creped fibrous structure.

17 . The compacted fibrous structure article according to claim 1 wherein the fibrous structure article comprises a conventional wet-pressed fibrous structure.

18 . The compacted fibrous structure article according to claim 1 wherein the compacted fibrous structure article comprises an ingredient selected from the group consisting of: antibacterial agents, antimicrobial agents, odor controlling agents, odor masking agents, perfumes, dry soap particles, surfactants, for example lathering and/or foaming surfactants, surface softening agents, lotions, polishing agents, dusting agents, and mixtures thereof.

19 . The compacted fibrous structure article according to claim 1 wherein the compacted fibrous structure article comprises a tab.

20 . The compacted fibrous structure article according to claim 1 wherein the tab is a machine-generated tab.
