A papermaking fabric for fibrous web forming or processing machines extends in MD and CD-directions and includes top and bottom fabric layers bound by binder yarns. The top layer is a web contacting side with top weave structures having interwoven first MD and first CD-yarns. The bottom layer is a machine contacting side with bottom weave structures having interwoven second MD and second CD-yarns. The top weave structure has repeats and forms fiber compression areas and fiber support areas recessed in thickness direction of the fabric relative to the fiber compression areas on the web side and fiber support areas separated by fiber compression areas or vice versa. A fiber compression area has adjacent top MD-floats on the web side or adjacent top CD-floats on the web side and a fiber support area has first MD and first CD-yarns interwoven in plain weave.

A clothing for paper or pulp dewatering machines comprising monofilaments comprising a partially aromatic polyamide. A machine-side fabric layer is provided, and at least the machine-side fabric layer comprises monofilaments with a partially aromatic polyamide. The clothing comprises or is formed by longitudinal threads extending in a running direction and transverse threads extending transversely to the longitudinal threads, and at least some of the transverse filaments are monofilaments with a partially aromatic polyamide.

A structured tissue belt assembly including a supporting layer, a non-woven web contacting layer, and one or more laser welds that attach the bottom surface of the web contacting layer to the top surface of the supporting layer. The structured tissue belt assembly allows for air flow in x, y and z directions. In exemplary embodiments, the structured tissue belt assembly has an embedment distance between the supporting layer and the web contacting layer of 0.05 mm to 0.60 mm and a peel force between the web contacting layer and the supporting layer of at least 650 gf/inch.
