Further, the needle dial uses a first tucking mode to perform tucking, and the needle cylinder uses a second tucking mode to perform tucking.
Further, the needle dial uses a second tucking mode to perform tucking, and the needle cylinder uses a first tucking mode to perform tucking.
Further, both the dial and the needle cylinder are tucked in a second tucking mode.
Further, the 6-way inlet wire of the circular knitting machine is a cycle, the 1 st way and the 4 th way are tuck loops, the 2 nd way and the 5 th way are upper single-side weft flat structures, and the 3 rd way and the 6 th way are lower single-side weft flat structures.
Further, the upper knitting needle and the lower knitting needle are both AB row needles.
Further, the 8-way inlet wire of the circular knitting machine is a cycle, the 1 st way, the 2 nd way, the 5 th way and the 6 th way are tuck loops, the 3 rd way and the 7 th way are upper single-side weft flat structures, and the 4 th way and the 8 th way are lower single-side weft flat structures.
Further, the upper knitting needle and the lower knitting needle are both ABCD rows of knitting needles.
As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects: the knitting needle first walks to the highest point of the needle outlet track along the needle outlet track in a second loop collecting mode, so that a new loop is hooked in a needle hook of the knitting needle, an old loop is looped, slides onto a needle bar, and is separated from a needle tongue; the knitting needle walks to a second tucking point along the narrowing track, the old stitch rises, the latch is closed, at the moment, the old stitch moves to the outer side of the latch but is not completely separated from the needle head part of the knitting needle, and the knitting needle keeps the state to move to the next needle outlet track; the new and old loops are simultaneously separated from the needle tongue and slide down onto the needle bar by walking along the next needle outlet track. The old loop is separated from the latch, the old loop is kept at the outer side of the latch and is not separated from the needle head part of the knitting needle, and finally the new loop and the old loop are concentrated at the outer side of the knitting needle instead of in the needle hook of the knitting needle, so that the loop collection can be completed without prolonging the latch part under the condition that the knitting needle has a larger difference between the highest point and the lowest point, the complete height difference from the lowest point to the highest point of the knitting length of the monofilament can be ensured, and the thickness of a sandwich tissue is increased.
