Abstract

A package containing at least one soft fibrous wipe laminate; the wipe laminate comprising a nonwoven wipe layer formed from a nonwoven web comprised predominantly of thermoplastic polymer, copolymer or blend fibers; and a backing layer bonded to the wipe layer where the nonwoven fibrous web has bonded regions and unbonded regions the unbonded region forming the arcuate mounds.

Claims

1. A soft fibrous wipe laminate, the wipe laminate comprising:

a nonwoven wipe layer formed from at least one nonwoven web comprised of fibers formed from thermoplastic polymers, copolymers or blends; and

a backing layer bonded to the wipe layer where the nonwoven fibrous web has bonded regions and unbonded regions, the unbonded region forming arcuate mounds wherein the wipe is a discrete laminate unattached to additional substrates and provided with a plurality of like wipes.

2. The wipes of claim 1 wherein the wipe layer is a nonwoven fibrous web having a basis weight of from 10 to 100 grams/m² and the fibrous wipe layer has a z-direction from the backing of at least 0.5 mm, and the arcuate mound comprises 20 to 99 percent of wipe laminate.

3. The wipes of claim 2 wherein the wipe layer has an impregnated active agent.

4. The wipes of claim 2 wherein the nonwoven wipe layer is formed of at least 10 percent bondable thermoplastic fibers by weight.

5. The wipes of claim 2 wherein the nonwoven wipe layer is formed of at least 20 percent bondable thermoplastic fibers by weight.

6. The wipes of claim 4 wherein the nonwoven wipe layer contains at least in part hydrophilic fibers.

7. The wipes of claim 6 wherein hydrophilic fibers are natural fibers.

8. The wipes of claim 4 wherein the backing layer is a thermoplastic layer that is autogeneously bonded to the nonwoven wipe layer.

9. The wipes of claim 8 wherein the backing layer is a thermoplastic film.

10. The wipes of claim 8 wherein the backing layer is a plurality of mutually parallel thermoplastic filaments.

11. The wipes of claim 2 wherein the backing layer has a basis weight of from 15 to 150 g/m².

12. The wipes of claim 11 wherein the nonwoven wipe layer has a basis weight offrom 15 to 50 g/m².

13. The wipes of claim 2 wherein the fibers forming the wipe layer are predominantly 1 to 50 μ

m in diameter.

14. The wipes of claim 2 wherein the wipe material laminate is from 10 to 100 cm² and has a basis weight of from 30 to 300 g/m².

15. The wipes of claim 2 wherein the wipe material laminate is from 20 to 50 cm² and has a basis weight of from 40 to 100 g/m².

16. The wipes of claim 2 wherein the wipes are in a package of wipe laminates which contain at least 10 wipes.

17. The wipes of claim 2 wherein the arcuate mounds are regular in shape.

18. The wipes of claim 2 wherein the mounds are irregular in shape.

19. The wipes of claim 2 wherein the arcuate mounds comprise from 50 to 95 percent of the cross sectional area of the wipe laminate.

20. The wipes of claim 2 wherein 99.5 to 50 percent of the cross sectional area of the nonwoven fibrous wipe layer in the wipe laminate is unbonded.

21. The wipes of claim 2 wherein the bonded portion of the nonwoven wipe layer is are bonded to the backing layer, have a width of from 0.01 to 0.2 cm and adjacent bonded portions are spaced on average from 0.1 to 2.0 cm apart.

22. The wipes of claim 2 wherein the z-direction loft is from 1 to 5 mm.

23. The wipes of claim 2 wherein the nonwoven fibrous wipe layer comprises at least 50 percent thermoplastic fiber.

24. The wipes of claim 2 wherein the nonwoven fibrous wipe layer comprises at least 75 percent thermoplastic fiber.

25. The wipes of claim 2 wherein the wipes have at least 20 percent greater water or oil absorption capacity than a corresponding nonwoven wipe layer without arcuate mounts.

26. The wipes of claim 2 wherein the wipes have at least 40 percent greater water or oil absorption capacity than a corresponding nonwoven wipe layer without arcuate mounts.

27. The wipes of claim 2 wherein the wipe forms foam height at least 45 percent higher than a corresponding nonwoven wipe layer without arcuate mounds.

28. The wipes of claim 2 wherein the wipe forms foam height at least 30 percent higher than a corresponding nonwoven wipe layer without arcuate mounds.

29. The wipes of claim 11 wherein nonwoven wipe layer is a carded fiber nonwoven web.

30. The wipes of claim 2 wherein the fibers forming the nonwoven wipe layer of from 1 to 70 μ
