5612 to form the binding yarns 333 and 633 as the needle foot crocheted to form the pile yarn warp loops 4312 5312 4612 and 5612 and the needle foot crocheted to form the bind yarn warp stitches 4323 5323 4623 and 5623 travel on different tracks of a cam hence the cam of the needles of the pile yarn warp loops 4312 5312 4612 and 5612 can be designed in a regular cycle on a plain track without crocheting the yarns 33 and 63 to form the binding yarns 333 and 633 and the cam of the needles of the pile yarn warp loops 4323 5323 4623 and 5623 can be designed in a regular cycle on a plain track without crocheting the yarns 31 and 61 to form the float yarns 3111 and 6111 the binding yarns 333 and 633 and the float yarns 3111 and 6111 can be designed to cross each other as shown in fig4 b after the float yarns 3111 and 6111 are cut to form the pile ends 3111 and 611 they also are bound by the binding yarns 333 and 633 thus are fastened securely and less likely to loosen off refer to fig5 a and 5b for a fragmentary schematic view of a second type structure of the corduroy fabric of the invention it is substantially the same as the one shown in fig3 a and 3b the main difference is as follow in the drawings the fabric formed by two transverse weft yarn sets 3 and 6 also are marked for discussion the transverse weft yarn set 3 includes three yarns 31 32 and 33 and is crocheted separately by needles of.
