Abstract

Fibrous structures that exhibit a novel combination of properties and to methods for making such fibrous structures are provided.

Claims (20)

1. A wet wipe comprising a fibrous structure comprising a liquid composition and one or more fibrous structure plies wherein each fibrous structure ply comprises a plurality of filaments and a plurality of solid additives randomly dispersed throughout the fibrous structure ply, wherein the wet wipe exhibits a Liquid Absorptive Capacity of greater than 12 g/g as measured according to the Liquid Absorptive Capacity Test Method and a Soil Leak Through Lr Value of less than 8.5 as measured according to the Soil Leak Through Test Method.

2. The wet wipe according to claim 1 wherein the wet wipe exhibits a Liquid Absorptive Capacity of greater than 13 g/g.

3. The wet wipe according to claim 1 wherein the wet wipe exhibits a Soil Leak Through Lr Value of less than 2.

4. The wet wipe according to claim 1 wherein the fibrous structure exhibits a CD Wet Initial Tensile Strength of greater than 5.0 N as measured according to the CD Wet Initial Tensile Strength Test Method.

5. The wet wipe according to claim 1 wherein the Basis Weight of the fibrous structure is less than 55 g/m 2 as measured according to the Basis Weight Test Method.

6. The wet wipe according to claim 1 wherein the liquid composition comprises a lotion composition.

7. The wet wipe according to claim 6 wherein the wet wipe exhibits a Lotion Release of greater than 0.25 as measured according to the Lotion Release Test Method.

8. The wet wipe according to claim 7 wherein the wet wipe exhibits a Dynamic Absorption Time of less than 0.04 as measured according to the DAT Test Method.

9. The wet wipe according to claim 7 wherein a stack of the wet wipe exhibits a Saturation Gradient Index of less than 1.5.

10. The wet wipe according to claim 1 wherein at least one of the solid additives comprises a fiber.

11. The wet wipe according to claim 10 wherein the fiber comprises a wood pulp fiber.

12. The wet wipe according to claim 11 wherein the wood pulp fiber is selected from the group consisting of: Southern Softwood Kraft pulp fibers, Northern Softwood Kraft pulp fibers, Eucalyptus pulp fibers, Acacia pulp fibers.

13. The wet wipe according to claim 1 wherein at least one of the filaments comprises a thermoplastic polymer.

14. The wet wipe according to claim 13 wherein the thermoplastic polymer is selected from the group consisting of: polypropylene, polyethylene, polyester, polylactic acid, polyhydroxyalkanoate, polyvinyl alcohol, polycaprolactone and mixtures thereof.

15. The wet wipe according to claim 1 wherein at least one of the filaments comprises a natural polymer.

16. The wet wipe according to claim 15 wherein the natural polymer is selected from the group consisting of: starch, starch derivatives, cellulose, cellulose derivatives, hemicellulose, hemicellulose derivatives and mixtures thereof.

17. The wet wipe according to claim 1 wherein at least one surface of the wet wipe comprises a layer of filaments.

18. The wet wipe according to claim 1 wherein the wet wipe is an embossed wet wipe.

19. The wet wipe according to claim 1 wherein the wet wipe comprises one or more prints.

20. The wet wipe according to claim 1 wherein the wet wipe is a nonwoven.
