Tuck knit has two intermeshing points, the singer part is not available in this loop, and the legs are spread. Only catching the yarn, no clearing and knocking. The tuck loop is always associated with a held loop. The held loop is actually bigger in size because it has been held by the needle for multiple courses, because of that the length of that loop will increase, so it pulls the fabric in the length directions, becauseand of that the length of the loop will increase, due to that a kind of shrinkage in the length direction and the fabric to relax in width direction because its legs are open so tuck knit fabric width along the course direction will increase Wider, More thickness, width-wise slightly less extensible
