PAPERMAKING FABRIC, IN PARTICULAR FOR USE IN THE FORMING SECTION OF A PAPERMAKING MACHINE

摘要

A quadruple papermaking fabric (100) comprises: a set of longitudinal machine direction (MD) top yarns (1-12); a set of cross machine direction (CMD) top yarns (37-42) interwoven with the top MD yarns to form a top fabric layer (101); a set of central MD yarns (13-24); a set of central CMD yarns (43-48) interwoven with the central MD yarns to form a central fabric layer (102); a set of bottom MD yarns (25-36); a set of bottom CMD yarns (49- 54) interwoven with the bottom MD yarns to form a bottom fabric layer (103); a set of pairs of binder yarns (55- 66) arranged in the cross machine direction and interwoven with the top MD yarns (1-12). At least one of the binder yarns (55-66) of each pair is interwoven with the central MD yarns (13-24) to form a first binding pattern (105) between the top layer (101) and the central layer (102); at least some of the central CMD yarns (43-48) define respective stitching yarns that are interwoven with the bottom MD yarns (25-36) to form a second binding pattern (106) between the central layer (102) and the bottom layer (103).
