zone wherein a filter material is bonded over the channels, subquently providing strips of polymeric material transver to the warp strips and bonding them thereto to form the weft of the network. The warp and weft may be produced from yarn reinforced polymeric webbing which is heat bonded. Polyolefin materials, particularly polyethylene, are suitable. Reinforcing may be in the form of reinforcing polyester yarns preferably inrted in the longitudinal direction in bundles. The filter fabric may also be a thermoplastic material, heat bonded, needle punched or woven. The filter fabric is adhered to, the warp using an elevated temperature and pressure.
