Abstract

A fibrous structure may include a plurality of wetformed knuckles or pillows, where the wet-formed knuckles or pillows of the pattern may form a plurality of rows oriented in an X-direction and/or a Y-direction, and the plurality of rows may be curved in a repeating wave pattern, where the repeating wave pattern may have an amplitude and a wavelength, and wherein the amplitude may be between about 0.75 mm and about 3.0 mm, and the wavelength may be between about 25.0 mm and about 125.0 mm.

Claims (21)

1. A fibrous structure comprising a plurality of wet-formed knuckles, wherein the wet-formed knuckles form a plurality of rows oriented in an X-direction and/or a Y-direction, and wherein the plurality of rows is curved in a repeating wave pattern, wherein the wave pattern has an amplitude and a wavelength, wherein the amplitude is between about 0.75 mm and about 3.0 mm, and the wavelength is between about 25.0 mm and about 125.0 mm, and wherein the fibrous structure has a TS7 of between about 0.01 dB V 2 rms and about 20.00 dB V 2 rms.

2. The fibrous structure of claim 1 , wherein the wave pattern is a sinusoidal wave pattern.

3. The fibrous structure of claim 1 , wherein the amplitude is between about 1.0 mm and about 2.5 mm.

4. The fibrous structure of claim 1 , wherein the wavelength is between about 25.0 mm and about 75.0 mm.

5. The fibrous structure of claim 1 , wherein an amplitude to wavelength ratio is between about 0.025 to about 0.05.

6. The fibrous structure of claim 1 , wherein the plurality of wet-formed knuckles are characterized by:

1) the plurality of wet-formed knuckles within the pattern have substantially the same shape, and

2) at least two of the plurality of wet-formed knuckles within the pattern have varying size.

7. The fibrous structure of claim 1 , wherein the fibrous structure has an SST (Slope of the Square Root of Time) rate of between about 1.60 g/sec 0.5 and about 2.50 g/sec 0.5 .

8. The fibrous structure of claim 1 , wherein the fibrous structure has a Plate Stiffness of between about 12 N*mm and about 20 N*mm.

9. The fibrous structure of claim 1 , wherein the fibrous structure has a Resilient Bulk of between about 85.0 cm 3 /g and about 110.0 cm 3 /g.

10. The fibrous structure of claim 1 , wherein the fibrous structure has a Total Wet Tensile of between about 400 g/in and about 900 g/in.

11. A fibrous structure comprising a plurality of wet-formed pillows, wherein the wet-formed pillows form a plurality of rows oriented in an X-direction and/or a Y-direction, and wherein the plurality of rows is curved in a repeating wave pattern, wherein the wave pattern has an amplitude and a wavelength, wherein the amplitude is between about 0.75 mm and about 3.0 mm, and the wavelength is between about 25.0 mm and about 125.0 mm, and wherein the fibrous structure has a TS7 of between about 0.01 dB V 2 rms and about 20.00 dB V 2 rms.

12. The fibrous structure of claim 11 , wherein the wave pattern is a sinusoidal wave pattern.

13. The fibrous structure of claim 11 , wherein the amplitude is between about 1.0 mm and about 2.5 mm.

14. The fibrous structure of claim 11 , wherein the wavelength is between about 25.0 mm and about 75.0 mm.

15. The fibrous structure of claim 11 , wherein an amplitude to wavelength ratio is between about 0.025 to about 0.05.

16. The fibrous structure of claim 11 , wherein the fibrous structure has a TS7 of between about 0.01 dB V 2 rms and about 20.00 dB V 2 rms, and an SST rate of between about 1.60 g/sec 0.5 and about 2.50 g/sec 0.5 .

17. The fibrous structure of claim 11 , wherein the fibrous structure has a Plate Stiffness of between about 12 N*mm and about 20 N*mm.

18. The fibrous structure of claim 11 , wherein the fibrous structure has a Resilient Bulk of between about 85.0 cm 3 /g and about 110.0 cm 3 /g.

19. The fibrous structure of claim 11 , wherein the fibrous structure has a Total Wet Tensile of between about 400 g/in and about 900 g/in.
