Abstract

A woven dryer fabric A having a low fabric permeability characteristic is disclosed having multiple layers in which an intermediate layer includes cabled multi-filament weft elements (B) consisting of low-melt monofilament strands twisted together which are melted in the fabric to effect closure of the fabric mesh. In the weaving process, the cabled multi-filament weft elements have a softer texture which renders them more flexible and allows a more dense mesh count to provide for greater pre-melt void coverage. After melt, the multi-filaments become fused and flow into the void areas of the shed for more complete void coverage.
