In the knitted fabric, most of the existing twill fabrics are knitted by a multi-axial warp knitting machine. The laid short fibers are woven into the base fabric, and the formed warp-knitted fabric has strength defects because the short fibers are broken, so that the requirement used in the field of industrial engineering cannot be met. The 45-degree yarns are laid on a rail behind the machine, and when the grooved needles rise, the yarns are pushed up from the lower surfaces of the 45-degree yarns laid on the rail, so that the yarns are 45-degree twill yarns, but the yarns are uneven, some needle backs have 2 needles, some needle backs have empty pads, and the strength is uneven. There is also a biaxial warp knitting machine which has only 90 ° of inlay yarn at the back of the needle, no 45 °, and no bias tensile strength as well. The two machines can not produce bidirectional twill and 45-degree twill cloth with high firmness and high strength.

After the 90-degree longitudinal weft insertion guide bar, the 45-degree oblique weft insertion guide bar and the 0-degree transverse weft insertion guide bar pass through respective needle shifting, a knitting chain guide bar loops yarns of 0 degree, 45 degrees on the left, 45 degrees on the right and 90 degrees in front of the needles of the grooved needles, and the twill cloth of the super warp machine is knitted.

Furthermore, the oblique weft insertion guide bar continuously moves needles along the machine head or the machine tail to reach the width edge to turn back. The slant weft insertion guide bar carries the slant weft insertion guide bar yarn to make 45-degree padding yarn on the back of the groove needle bed to form 45-degree twill yarn.

Further, the transverse weft insertion guide bar carries the transverse weft insertion guide bar yarn to carry out transverse lapping yarn on the back of the groove needle bed, and the 0-degree twill yarn is formed.

Further, the longitudinal weft insertion guide bar carries longitudinal weft insertion guide bar yarns to transversely move longitudinal lapping yarns at the back of a groove needle of the groove needle bed to form yarns with 90 degrees of twill.

Furthermore, the chain knitting guide bar carries out yarn laying movement in front of the groove needle bed to form a coil, and the yarns of 0 degree, 45 degrees on the left, 45 degrees on the right, 90 degrees and the like are sleeved to form a fabric with weft insertion in four directions.

The invention has the beneficial effects that: a chain guide bar is laid in front of a grooved needle to form chain laying yarns, then a transverse weft insertion guide bar is used for laying yarns on the left and the right of the needle back of the grooved needle to form 0-degree laying yarns, a diagonal weft insertion guide bar is used for making twill laying yarns to form 45-degree cross laying yarns, a longitudinal weft insertion guide bar is used for making 90-degree laying yarns on the needle back of the grooved needle, and thus 0-degree, 45-degree and 90-degree laying yarns are formed, and the twill cloth of the super-warp machine is provided.
