Abstract

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

First claim

What is claimed is:

1. A wet wipe comprising a liquid composition, 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 wet wipe 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 wet wipe 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 wet wipe exhibits a pore volume distribution such that at least 43% of the total pore volume present in the wet wipe exists in pores of radii of from 91 μm to 140 μm as measured according to the Pore Volume Distribution Test Method.

7. The wet wipe according to claim 1 wherein the wet wipe exhibits a pore volume distribution such at that at least 30% of the total pore volume present in the wet wipe exists in pores of radii of from 121μm to 200 μm.

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

9. The wet wipe according to claim 8 wherein the wet wipe exhibits a Lotion Release of greater than 0.25 as measured according to the Lotion Release Test Method.

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

11. The wet wipe according to claim 8 wherein a stack of the wet wipes exhibits a Saturation Gradient Index of less than 1.5.

12. The wet wipe according to claim 1 wherein the wet wipe comprises a plurality of filaments.

13. The wet wipe according to claim 12 wherein the wet wipe further comprises a plurality of solid additives.

14. The wet wipe according to claim 13 wherein at least one of the solid additives comprises a fiber.

15. The wet wipe according to claim 14 wherein the fiber comprises a wood pulp fiber.

16. The wet wipe according to claim 15 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.

17. The wet wipe according to claim 12 wherein at least one of the filaments comprises a thermoplastic polymer.

18. The wet wipe according to claim 17 wherein the thermoplastic polymer is selected from the group consisting of: polypropylene, polyethylene, polyester, polylactic acid, polyhydroxyalkanoate, polyvinyl alcohol, polycaprolactone and mixtures thereof.

19. The wet wipe according to claim 12 wherein at least one surface of the wet wipe comprises a layer of filaments.

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