Full-forming flat knitting machine garment side seam slit overlapping knitting method and knitted fabric

A flat knitting machine with more than one pair of front and back needle beds which extend in the left-right direction and are opposite to each other in the front-back direction is used, it is assumed that a yarn nozzle A is used for knitting a large body back piece before side seam slit, and a yarn nozzle B is used for knitting a large body front piece; a plurality of knitting needles are used as overlapping needle positions before the side seams are slit, the overlapping needle positions are smaller than or equal to 8 needles, and the overlapping needle positions are overlapped front and back in a sequential needle turning mode at the slit ending position, so that the effect that the side seams of the front part wrapping the rear part are slit and overlapped is achieved through knitting. According to the invention, by using a cross knitting and needle turning mode at the slit, the coils of the body front piece are overlapped on the body front piece, so that the appearance is more attractive, and the slit is
