Abstract
A flat-knitted three-dimensional fabric with an internal support structure, and the fabric is consisted of an upper surface layer, a lower surface layer, and a support structure yarn in a middle, wherein the upper surface layer and the lower surface layer comprise alternate-knitted single-sided stitches and fully-knitted single-sided stitches; the upper surface layer and the lower surface layer are connected by means of tuck knitting of the support structure yarn in the middle to form the integrally formed three-dimensional fabric with an internal support structure; and the alternate-knitted single-sided stitches are correspond to tuck loops formed by the support structure yarn and are used to lock the tuck loops formed by the support structure yarn in the middle, such that the support structure yarn will not puncture the surfaces of the fabric when the fabric is pressed.
