Abstract

Belts and fibrous structures of the present disclosure may comprise discrete cells comprising one or more legs and/or one or more concavities in certain patterns or Cell Groups. The cells may be discrete knuckles or pillows and the fibrous structures may further comprise an emboss.

Claims (31)

1. A fibrous structure comprising a plurality of discrete wet-formed knuckles extending from a pillow surface of the fibrous structure, wherein each of the plurality of discrete wet-formed knuckles comprises a saddle and at least two legs, wherein the plurality of discrete wet-formed knuckles have a Cell Width, a Saddle Height, a Saddle Width, a Leg Length and a Leg Width wherein the pillow surface has a Distance Between Saddles, a Distance Between Cells, a First Leg Separation Distance, a Second Leg Separation Distance, a first pillow density and a second pillow density; and wherein:

a. a ratio of the First Leg Separation Distance to the Distance Between Saddles is between about 0.050 and about 0.99;

b. a ratio of the Leg Length to the Saddle Height is between about 1.02 and about 24.0; and

c. the first pillow density is at least 5% different than the second pillow density.

2. The fibrous structure of claim 1 , wherein the ratio of the First Leg Separation Distance to the Distance Between Saddles is between about 0.33 and about 0.56.

3. The fibrous structure of claim 1 , wherein the ratio of the Leg Length to the Saddle Height is between about 4.67 and about 6.0.

4. The fibrous structure of claim 1 , wherein the Cell Width is between about 0.035 inch and about 0.480 inch.

5. The fibrous structure of claim 1 , wherein the Saddle Height is between about 0.008 inch and about 0.180 inch.

6. The fibrous structure of claim 1 , wherein the Saddle Width is between about 0.020 inch and about 0.210 inch.

7. The fibrous structure of claim 1 , wherein the Leg Length is between about 0.020 inch and about 0.240 inch.

8. The fibrous structure of claim 1 , wherein the Leg Width is between about 0.008 inch and about 0.180 inch.

9. The fibrous structure of claim 1 , wherein the Distance Between Saddles is between about 0.040 inch and about 0.350 inch.

10. The fibrous structure of claim 1 , wherein the Distance Between Cells is between about 0.020 inch and about 0.210 inch.

11. The fibrous structure of claim 1 , wherein the First Leg Separation Distance is between about 0.020 inch and about 0.200 inch.

12. The fibrous structure of claim 1 , wherein the Second Leg Separation Distance is between about 0.020 inch and about 0.200 inch.

13. The fibrous structure of claim 1 , wherein the fibrous structure has a basis weight of between about 25.0 lb/3000 ft 2 and about 60.0 lb/3000 ft 2 .

14. The fibrous structure of claim 1 , wherein the fibrous structure has a CRT Capillary Rate Initial Rate of between about 0.30 g/s and about 1.00 g/s.

15. The fibrous structure of claim 1 , wherein the fibrous structure has a CRT Capillary Rate Capacity Ratio of between about 12.5 g/g and about 23.0 g/g.

16. The fibrous structure of claim 1 , wherein the fibrous structure has a Wet Burst Peak Load of between about 200 g and about 700 g.

17. The fibrous structure of claim 1 , wherein the fibrous structure has a Dry Caliper of between about 26.0 mils and about 80.0 mils.

18. The fibrous structure of claim 1 , wherein the fibrous structure has a Wet Caliper of between about 17.0 mils and about 70.0 mils.

19. The fibrous structure of claim 1 , wherein the fibrous structure has a Total Tensile of between about 1300 g/M and about 4000 g/M.

20. The fibrous structure of claim 1 , wherein the fibrous structure has a Geometric Mean Dry Modulus of between about 1000 g/cm and about 3500 g/cm.

21. The fibrous structure of claim 1 , wherein the fibrous structure has a ratio of Flexural Rigidity to Total Dry Tensile of between about 0.20 and about 0.65.

22. The fibrous structure of claim 1 , wherein the fibrous structure has a Slipstick of between about 800 and about 1150.

23. The fibrous structure of claim 1 , wherein the fibrous structure has a Kinetic Coefficient of Friction of between about 0.85 and about 1.20.

24. The fibrous structure of claim 1 , wherein the fibrous structure has a TS7 value of between about 14.0 dB V 2 rms and about 40.0 dB V 2 rms.

25. The fibrous structure of claim 1 , wherein the fibrous structure has a TS750 value of between about 40.0 dB V 2 rms and about 100.0 dB V 2 rms.

26. The fibrous structure of claim 1 , wherein the fibrous structure has a Geometric Mean Wet Modulus of between about 250 g/cm and about 525 g/cm.

27. The fibrous structure of claim 1 , wherein the fibrous structure has a Total Wet Tensile of between about 300 g/M and about 1000 g/M.

28. The fibrous structure of claim 1 , wherein the fibrous structure has a SST of between about 0.80 g/sec 0.5 and about 2.5 g/sec 0.5 .
