COMPOSITE FORMING FABRIC Abstract of the Disclosure A composite paper-making forming fabric of re- duced thickness and having improved fiber retention. The fabric comprises at least two complete weaves, each formed by its own set of warp and weft yarns and being interconnected by binder yarns which are separately inter- woven with the two complete weaves. An upper one of the complete weaves constitutes a paper-side weave which is comprised of flattened warp yarns having an aspect ratio of width to height of between 1.20 and 2.30 and inter- woven with the weft yarns and having a plain weave. The bottom one of the complete weaves constitutes the machine- side weave which is comprised of flattened warp yarns having an aspect ratio of width to height of between 1.20 and 2.30. The bottom weave has a mesh count of sub- stantially half that of the upper weave. The upper weave has a machine-direction frame length which is less than that when round warp yarns are used. The product of the warp mesh count and the width of the flattened warp strands in the upper weave is not more than about 0.65.
