are separated by a light denier yarn 208 the binder warp yarns 220 221 222 223 are preferably 1 000 denier yarns and the weft yarns 206 207 are preferably approximately 0 3 mm monofil yarns the fabric 201 is woven in a repeating weaving pattern wherein four binder warp yarns 220 221 222 and 223 are woven in a specified pattern through a plurality of couplets formed from pairs of aligned weft yarns of layers 206 207 in this pattern the first binder warp yarn 220 extends over a first aligned couplet of weft yams 210 and under the second third and fourth couplets 211 212 and 213 respectively the second warp yarn 221 extends over the second couplet of weft yarns 211 and under the third fourth and fifth couplets 212 213 and 214 respectively the third warp yarn 222 extends over the third couplet of weft yarns 212 and under the fourth fifth and sixth couplets 213 214 and 215 respectively and the fourth warp yarn 223 extends over the fourth couplet of weft yarns 213 and under the fifth sixth and seventh couplets 214 215 and 216 respectively the specific pattern of the binder yarns of fig4 is further illustrated in fig5 in which the pattern of a single binder warp yarn yarn 221 is shown separate from the other binder warp yarns belt material in accordance with the present invention is preferably manufactured by feeding the woven belt fabric e g 100.
