The invention relates to the technical field of knitting of circular knitting machines, in particular to a knitting process for tight loops of a loop transfer jacquard, which is realized based on cooperation of a lower knitting needle, an upper knitting needle, a connecting needle, an upper triangle, a lower triangle, a reset triangle and a pattern bit of the loop transfer jacquard, a small boss is arranged at a needle raising position of the lower triangle, and a hollowed reset area is arranged in the middle of the lower triangle; the process comprises the following steps: when a lower knitting needle runs into a plain stitch, a needle hook of the lower knitting needle extends out above the height of a cylinder opening of a lower needle cylinder under the action of a small boss at a needle raising position of a lower triangle, so that the needle hook of the lower knitting needle blocks a coil at a needle raising position of an upper knitting needle; the lower knitting needle drives the connecting needle to move to a hollowed-out reset area in the middle of the lower triangle; by controlling the lifting height of the lower knitting needle during raising, the hook of the lower knitting needle can effectively block a coil at the raising position of the upper knitting needle, the problems that in the prior art, the coil of the upper needle is too loose, tight adjustment is achieved, and the upper needle is prone to being raised and ejected are thoroughly solved, and a stable initial condition is provided for tight forming of the coil of the upper needle.
