Abstract

Claims (34)

1. An absorbent fabric-creped cellulosic web comprising:

(a) a plurality of fiber-enriched regions having a relatively high local basis weight, the fiber-enriched regions comprising a plurality of microfolds with fold lines extending transverse to the machine direction (MD) and having a fiber bias in the cross-machine direction (CD); and

(b) a plurality of lower local basis weight linking regions interconnecting the fiber-enriched regions.

2. The absorbent cellulosic web according to claim 1 , wherein the linking regions have a fiber bias extending along a direction between fiber-enriched regions.

3. The absorbent cellulosic web according to claim 1 , wherein the fiber-enriched regions are attenuated or dispersed in the MD.

4. The absorbent cellulosic web according to claim 1 , wherein the web comprises secondary fiber.

5. The absorbent cellulosic web according to claim 4 , wherein the web comprises at least fifty percent by weight secondary fiber.

6. The absorbent cellulosic web according to claim 1 , wherein the web has a basis weight of from about 5 to about 30 lbs per 3000 square feet ream.

7. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a five percent increase in void volume upon being drawn.

8. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a twenty-five percent increase in void volume upon being drawn.

9. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a thirty-five percent increase in void volume upon being drawn.

10. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a fifty percent increase in void volume upon being drawn.

11. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a five percent increase in void volume upon being drawn by at least about thirty percent.

12. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a twenty percent increase in void volume upon being drawn by at least about forty-five percent.

13. The absorbent cellulosic web according to claim 1 , wherein the web exhibits an increase in void volume of at least about 1 g/g upon being drawn.

14. The absorbent cellulosic web according to claim 1 , wherein the web exhibits an increase in void volume of at least about 2 g/g upon being drawn.

15. The absorbent cellulosic web according to claim 1 , wherein the web exhibits an increase in void volume of at least about 3 g/g upon being drawn.

16. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a five percent increase in bulk upon being drawn.

17. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a five percent increase in bulk upon being drawn by at least about thirty percent.

18. The absorbent cellulosic web according to claim 1 , wherein the web exhibits at least about a ten percent increase in bulk upon being drawn by at least about forty-five percent.

19. The absorbent cellulosic web according to claim 1 , wherein the web has a recovered crepe of at least about ten percent.

20. The absorbent cellulosic web according to claim 1 , wherein the web has a recovered crepe of at least about twenty-five percent.

21. The absorbent cellulosic web according to claim 1 , wherein the web has a recovered crepe of at least about fifty percent.

22. The absorbent cellulosic web according to claim 1 , wherein the web has a recovered crepe of at least about one hundred percent.

23. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a ratio of percent decrease in caliper/percent decrease in basis weight of the web of less than about 0.85 upon being drawn.

24. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a ratio of percent decrease in caliper/percent decrease in basis weight of the web of less than about 0.7 upon being drawn.

25. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a ratio of percent decrease in caliper/percent decrease in basis weight of the web of less than about 0.6 upon being drawn.

26. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a void volume of at least about 6 gm/gm.

27. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a void volume of at least about 7 gm/gm.

28. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a void volume of at least about 8 gm/gm.

29. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a void volume of at least about 9 gm/gm.

30. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a void volume of at least about 10 gm/gm.

31. The absorbent cellulosic web according to claim 1 , wherein the web exhibits a decrease in sidedness upon being drawn.

32. The absorbent cellulosic web according to claim 1 , wherein the web exhibits an absorbency suitable for use in tissue and towel products.
