Abstract

Fibrous structures, more particularly fibrous structures comprising a region of auxiliary bonding and methods for making same are provided.

Claims

1. A single- or multi-ply sanitary tissue product comprising two or more contiguous sheets perforated by a perforation region such that the two or more contiguous sheets can be separated from one another during use by a consumer, wherein the sanitary tissue product exhibits a density of less than 0.15 g/cm³ and comprises a fibrous structure comprising wood pulp fibers and a region of auxiliary bonding comprising an auxiliary bonding agent, wherein the auxiliary bonding agent comprises a dust inhibiting agent and wherein the region of auxiliary bonding contains within it a region of fiber disruption comprising a perforation region, wherein both regions are discrete and wherein the perforation region is contained within the auxiliary bonding agent.

2. The single- or multi-ply sanitary tissue product according to claim 1 wherein the region of fiber disruption further comprises protruding regions.

3. The single- or multi-ply sanitary tissue product according to claim 1 wherein the region of fiber disruption is a solid state disruption zone.

4. The single- or multi-ply sanitary tissue product according to claim 1 wherein the sanitary tissue product is a single-ply.

5. The single- or multi-ply sanitary tissue product according to claim 1 wherein the fibrous structure is convolutedly wound upon itself to form a roll of the sanitary tissue product.

6. A single- or multi-ply sanitary tissue product comprising two or more contiguous sheets perforated by a perforation region such that the two or more contiguous sheets can be separated from one another during use by a consumer, wherein the sanitary tissue product exhibits a density of less than 0.15 g/cm³ and comprises a fibrous structure comprising wood pulp fibers that exhibits a normalized dispensing dust value of less than about 3500, wherein the fibrous structure comprises a region of auxiliary bonding comprising an auxiliary bonding agent, wherein the auxiliary bonding agent comprises a dust inhibiting agent and wherein the region of auxiliary bonding contains within it a region of fiber disruption comprising a perforation region, wherein both regions are discrete and wherein the perforation region is contained within the auxiliary bonding agent.

7. A single- or multi-ply sanitary tissue product comprising two or more contiguous sheets perforated by a perforation region such that the two or more contiguous sheets can be separated from one another during use by a consumer, wherein the sanitary tissue product exhibits a density of less than 0.15 g/cm³ and comprises a fibrous structure comprising wood pulp fibers which has a dispensing dust value reduced by creating a region of auxiliary bonding wherein the region of auxiliary bonding comprises an auxiliary bonding agent and alters the dispensing dust by decreasing the normalized dispensing dust relative to the fibrous structure without the region of auxiliary bonding, wherein the auxiliary bonding agent comprises a dust inhibiting agent and wherein the region of auxiliary bonding contains within it a region of fiber disruption comprising a perforation region, wherein both regions are discrete and wherein the perforation region is contained within the auxiliary bonding agent.

8. The single- or multi-ply sanitary tissue product according to claim 7 wherein the area affected by the auxiliary bonding comprises less than 50% of the total area.

9. A single-ply sanitary tissue product comprising two or more contiguous sheets perforated by a perforation region such that the two or more contiguous sheets can be separated from one another during use by a consumer, wherein the sanitary tissue product exhibits a density of less than 0.15 g/cm³ and comprises wood pulp fibers, a solid state disruption zone comprising a perforation region, and an auxiliary bonding region comprising an auxiliary bonding agent within the sanitary tissue product, wherein the auxiliary bonding agent comprises a dust inhibiting agent and wherein the zone and the region partially overlap, wherein both regions are discrete and wherein the perforation region is contained within the auxiliary bonding agent.
