Abstract
Provided are woven papermaking fabrics useful in the manufacture of tissue products, particularly through-air dried tissue products. The fabrics generally have a plurality of protuberances disposed on the web contacting surfaces. The protuberances are formed from a plurality warp filaments interwoven with a plurality of shute filaments and have a hollow interior pocket, which is generally bounded by the warp and shute filaments. By providing protuberances with hollow interior pockets the air permeability of the resulting woven papermaking fabric may be improved, and in certain instances may be increased, relative to similar fabrics having protuberances that are non-hollow.
