8. A four-way reciprocating jacquard knitting method is characterized in that: the method comprises the following steps:
step one; the needle selector applies pressure to jacquard teeth of the jacquard needle, so that the upper end of the jacquard needle moves outwards, the relay needle is pushed to move towards the outer side of the needle cylinder, and the lower stitch of the relay needle is in contact with the left and right jacquard looping triangular jacquard looping work;
step two; the lower bottom in the middle of each left and right jacquard looping cam of the four groups of reciprocating jacquard mechanisms is provided with a needle selector which can carry out left-right reciprocating jacquard, the needle selector between the first group and the second group is responsible for the jacquard needle walking work of the left jacquard looping cam of the first path and the right jacquard looping cam of the second path, the needle selector between the second group and the third group is responsible for the jacquard needle walking work of the left jacquard looping cam of the second path and the right jacquard looping cam of the third path, the needle selector between the third group and the fourth group is responsible for the jacquard needle walking work of the left jacquard looping cam of the third path and the right jacquard needle walking work of the right jacquard looping cam of the fourth path, and the needle selector between the first group of the fourth group and the next path is responsible for the jacquard needle walking work of the left jacquard looping cam of the fourth path and the right jacquard looping cam of the first path;
step three; an auxiliary needle selector is arranged at the lower bottom of the water chestnut position in each group, and the lower stitch of the relay needle in the needle groove is pressed and warped out of the needle groove, so that the relay needle passes through a left jacquard looping triangle in each group and then is looped;
step four; and after the lower stitch of the relay stitch is pressed and looped by the left and right loop cams of each group, the upper stitch of the relay stitch is knitted and raised by the left and right loop cams of each group, so that the lower stitch of the relay stitch returns to a position where the relay stitch can wait for the next left and right jacquard operation.
