ABSTRACT:
A papermaker's fabric, usable with a dryer section on a paper machine, has a first layer and a second layer of cross-machine-direction (CD) yarns. Interwoven with the CD yarns in a duplex weave is a system of MD yarns. The MD yarns are provided in groups of at least two adjacent MD yarns. Each group has one first MD yarn and one or more second MD yarn. The first MD yarn interweaves between the first and second layers of CD yarns, each time binding with only one CD yarn. Each second MD yarn also interweaves between first and second layers of CD yarns, each time binding with only one CD yarn in the first layer, but floating over at least two CD yarns in the second layer. The first MD yarn is between the one or more second MD yarns in its group and those of an adjacent group, and defines a continuous air channel on the surface of the fabric.
