Title: Press felt for papermaking

Abstract: Press felts for papermaking include a batt fiber layer and a base fabric. The batt fiber layer is integrated into the base fabric. The base fabric includes a ground warp yarn, a ground weft yarn, and an additional warp yarn. The ground warp yarn and the ground weft yarn include monofilament yarns, and the additional warp yarn includes a material different from a material forming the ground warp yarn. The additional warp yarn is arranged so that, when the base fabric is viewed in cross-section in a warp yarn direction, the additional warp yarn ascends toward a wet paper web-side surface of the base fabric and descends toward a roll-side surface of the base fabric, relative to the at least one ground warp yarn.
