1. A structured tissue belt assembly, comprising:
a supporting layer comprising a top surface and a bottom surface, the supporting layer being formed of one or more layers of warp yarns interwoven with weft yarns in a repeating pattern, at least one of: a) at least some of the warp yarns; orb) at least some of the weft yarns, comprising laser energy absorbent material;
a non-woven web contacting layer comprising a bottom surface; and
one or more first laser-formed embedments that attach the bottom surface of the web contacting layer to the top surface of the supporting layer only at points where the web contacting layer contacts the at least one of: a) the at least some of the warp yarns; or b) the at least some of the weft yarns that comprise laser energy absorbent material, so that at least some points where the web contacting layer contacts the supporting layer remain unattached,
wherein the structured tissue belt assembly allows for air flow in x, y and z directions,
wherein an embedment distance between the supporting layer and the web contacting layer is 0.05 mm to 0.60 mm, and
wherein a peel force between the web contacting layer and the supporting layer is at least 650 gf/inch.
