Abstract

A triple papermaking fabric includes a set of warp machine direction top yarns; a set of weft cross machine direction top yarns interwoven with the top MD yarns to form a top fabric layer; a set of bottom MD yarns; a set of bottom CMD yarns interwoven with the bottom MD yarns to form a bottom fabric layer; and a set of binding yarns arranged in the cross machine direction and interwoven with the top MD yarns and binding the top layer to the bottom layer. The binding yarns are arranged in pairs between two adjacent top CMD yarns, and in a fabric repeat unit at least one binding yarn of each pair is interwoven with at least one bottom MD yarn. The ratio between weft yarns and warp yarns is 4:2.
