Abstract
A multi-layer papermaking fabric for use in a papermaking machine. The multi-layer fabric includes an upper fabric layer having a paper fiber support surface which is formed of first warp yarns interlaced with first weft yarns with at least one of these being knit yarns. Also, the lower fabric layer is formed of second warp yarns interlaced with second weft yarns. The construction of the knit yarns forms a series of loops which extend longitudinally and transversely of their longitudinal axis. These loops form the support surface with increased cover and provide for more uniform drainage of the paper forming fibers.
