US Patent 11920301 Woven papermaking fabric having intersecting twill patterns

Woven papermaking fabrics useful in the manufacture of fibrous structures, particularly wet-laid tissue products that allow the web contacting surface of the fabric to be woven with three-dimensional topography comprising protuberances that are oriented at an angle relative to both the machine direction (MD) axis and cross-machine (CD) axis of the fabric. The protuberances may be discrete or continuous and, in certain preferred embodiments, intersect one another to form discrete valleys there between. The valleys may have relatively steep sidewalls, such as wall angles greater than 22 degrees, and be relatively deep, such as valley depths greater than about 0.35 mm.
