Rippled papermaking fabrics for creped and uncreped tissue manufacturing processes

A woven papermaking fabric having a textured sheet contacting surface comprising substantially continuous machine-direction ripples separated by valleys, said ripples being formed of multiple warp strands grouped together, said ripples having a depth of between approximately 250 to 300 percent of a warp strand diameter, the fabric being a single layer fabric and having a cross-machine direction bending stiffness from about 20 to about 80 N·m.

A single layer, woven fabric having at least 40 features per square inch, and a textured sheet contacting surface having a z-direction depth of at least 0.8 mm, the fabric being a single layer fabric and having a cross-machine direction bending stiffness from about 20 to about 80 N·m.

A woven papermaking fabric having a textured sheet contacting surface comprising substantially continuous ripples aligned at an angle to a machine direction and separated by valleys, said ripples being formed of multiple warp strands grouped together and supported by multiple shute strands of two or more diameters, wherein the warp strands are substantially oriented in the machine direction and wherein each individual warp strand participates in both a structure of said ripples and a structure of said valleys, the fabric being a single layer fabric and having a cross-machine direction bending stiffness from about 20 to about 80 N·m.

A woven papermaking fabric having a textured sheet contacting surface comprising substantially continuous ripples aligned at a variable angle to a machine direction and separated by valleys, said ripples being formed of multiple warp strands grouped together and supported by multiple shute strands of two or more diameters, wherein the warp strands are substantially oriented in the machine direction and wherein each individual warp strand participates in both a structure of said ripples and a structure of said valleys, and wherein said variable angle of said fabric ripple regularly reverses direction in terms of traversing the cross-machine direction to thereby create a wavy-like appearance, the fabric being a single layer fabric and having a cross-machine direction bending stiffness from about 20 to about 80 N·m.
