shown again in fig2 to 22 the industrial fabric 3 is a 2 1 twill weave which includes the monofilament yarns 32 along the warp direction and the multifilament yarns 31 along the warp and weft directions 7 referring to fig2 to 25 the industrial fabric 3 is a 2 1 twill weave which includes the monofilament yarns 32 along the warp and weft directions and the multifilament yarns 31 along the warp and weft directions due to the twill weaving used to fabricate the industrial fabric 3 and due to the use of a large amount of the monofilament yarns 32 and or multifilament yarns 31 and the use of the multifilament yarns 31 including a large number of monofilament fibers 311 to compensate the insufficient strength resulting from the twill weaving the face side strength of the industrial fabric can reach a strength of 50 kn m and the water permeability thereof can amount to 900 litres m 2 in comparison with a conventional 25 kn industrial fabric with a water permeability of 111 litres m 2 or a conventional 45 kn industrial fabric with 270 litres m 2 the industrial fabric 3 can increase the water permeability up to.
