Abstract

Fibrous structures having a surface pattern of a continuous knuckle region and a plurality of discrete pillow regions such that the fibrous structures exhibit improved lotion transfer compared to known fibrous structures and better sheet control during the making of such fibrous structures are provided.

First claim

What is claimed is:

1. An embossed, structured fibrous structure comprising a surface comprising a surface pattern, plurality of fibrous elements and a lotion present on at least one surface of the embossed, structured fibrous structure such that the embossed, structured fibrous structure falls above a line having the following equation y=2.8202x graphed on a plot of Lotion Add-on Level (lbs/3000 ft 2 ) to Lotion Transfer (μg/cm 2 ) where the x-axis is Lotion Add-on Level (lbs/3000 ft 2 ) and the y-axis is Lotion Transfer (μg/cm 2 ); wherein the surface pattern comprises a knuckle region network and a plurality of pillow regions dispersed within the knuckle region network such that the fibrous structure exhibits a TS7 of less than 5.5 dB V 2 rms as measured according to the Emtec Test Method, wherein a repeat unit of the surface pattern is defined by two or more groups of two or more pillow regions dispersed in the knuckle region network, wherein at least two of the two or more groups of pillow regions are non-parallelly juxtaposed.

2. The embossed, structured fibrous structure according to claim 1 wherein the surface of the embossed, structured fibrous structure comprises a surface pattern comprising a repeat unit within the surface pattern comprising at least two groups of two or more pillows, wherein the at least two groups of two or more pillows are non-parallelly juxtaposed.

3. The embossed, structured fibrous structure according to claim 1 wherein the plurality of fibrous elements comprises a plurality of fibers.

4. The embossed, structured fibrous structure according to claim 3 wherein the plurality of fibers comprise a plurality of pulp fibers.

5. The embossed, structured fibrous structure according to claim 4 wherein the plurality of pulp fibers comprise a plurality of wood pulp fibers.

6. The embossed, structured fibrous structure according to claim 4 wherein the plurality of pulp fibers comprise a plurality of non-wood pulp fibers.

7. The embossed, structured fibrous structure according to claim 1 wherein the fibrous structure comprises a wet-laid, embossed, structured fibrous structure.

8. The embossed, structured fibrous structure according to claim 1 wherein the embossed, structured fibrous structure comprises an embossed through-air-dried fibrous structure.

9. The embossed, structured fibrous structure according to claim 8 wherein the embossed through-air-dried fibrous structure ply is a creped embossed through-air-dried fibrous structure.

10. The embossed, structured fibrous structure according to claim 8 wherein the embossed through-air-dried fibrous structure ply is an uncreped embossed through-air-dried fibrous structure.

11. The embossed, structured fibrous structure according to claim 1 wherein the embossed, structured fibrous structure comprises a fabric creped embossed fibrous structure ply.

12. The embossed, structured fibrous structure according to claim 1 wherein the embossed, structured fibrous structure comprises a belt creped embossed fibrous structure ply.

13. The embossed, structured fibrous structure according to claim 1 wherein the surface of the embossed, structured fibrous structure comprises a surface pattern comprising a molded microscopical three-dimensional pattern.

14. The embossed, structured fibrous structure according to claim 1 wherein the surface of the embossed, structured fibrous structure comprises a surface pattern, wherein the surface pattern comprises a knuckle region and a plurality of pillow regions dispersed within the knuckle region.

15. The embossed, structured fibrous structure according to claim 1 wherein the embossed, structured fibrous structure exhibits a lotion transfer of greater than 7.4μg/cm 2 as measured according to the Lotion Transfer Test Method.

16. The embossed, structured fibrous structure according to claim 1 wherein the embossed, structured fibrous structure falls above a line having the following equation y=0.0163x graphed on a plot of Lotion on Sheet (μg/cm 2 ) to Lotion Transfer (μg/cm 2 ) where the x-axis is Lotion on Sheet (μg/cm 2 ) a nd the y-axis is Lotion Transfer (μg/cm 2 ).

17. The embossed, structured fibrous structure according to claim 1 wherein the embossed, structured fibrous structure is a wet-laid embossed, structured fibrous structure.

18. A single- or multi-ply sanitary tissue product comprising an embossed, structured fibrous structure according to claim 1 .

19. A roll of sanitary tissue product comprising a single- or multi-ply sanitary tissue product according to claim 18 .

20. A package comprising one or more rolls of sanitary tissue product according to claim 19 .
