Method of knitting neck of knit wear by weft knitting machine and knit designing device for producing the method of knitting the neck

A method of knitting knitwear, comprising a front part of fabric having at least a front body and a back part of fabric having at least a back body by using a flat knitting machine comprising at least a pair of front and back needle beds, which are extended laterally and confront each other in back and front and at least either of which can be racked laterally to transfer stitches between the needles beds, the method comprising the step that the front part of fabric and the back part of fabric are knitted from their bottom hems to shoulders such that the front part of the fabric is associated with the first needle bed and the back part of the fabric is associated with the second needle bed, so that the front part of the fabric and the back part of the fabric are joined at both knitting-widthwise ends, so as to be knitted in the form of a tubular body;

• the step that during this process, the front body is knitted to be formed into a right front body and a left front body from a front neckline forming portion and also a flechage knitting that the stitches around a margin of the front neckline are sequentially slipped from the knitting to be put into inoperative positions is repeated a predetermined number of times, so as to form the neckline having a front drop in the front body;
• and the step that the front part of the fabric and the back part of the fabric are joined to each other at the shoulders, except at the front neckline and a back neckline, so that the knitwear is knitted into a seamless knit,
• the method further comprising the step that stitches at a right side of the front neckline and stitches at a left side of the front neckline, retained on the first needle bed, are shifted from inside to outside, with gradually increasing distances, so that those stitches are retained on the first needle bed, with empty needles inserted in the spaces between the stitches;
• the step that at least one of the shifted stitches at an outer side end portion of the right side of the front neckline and at least one of the shifted stitches at an outer side end portion of the left side of the front neckline are fed to the second needle bed so as to be situated next to the stitch at each side end of the back neckline retained on the second needle bed, whereby the stitches at each side end of each of the front and back necklines retained on the front and back needle beds are kept in positions close to each other, without being away from each other in a lateral direction to a large extent, as the neckline is increased in diameter, followed by formation of widening stitches on the empty needles and then knitting of a collar.
