Abstract
In a structure of a spacer fabric and a thickness-controlled knitting method for producing the same are disclosed, the method includes knitting a yarn into a three laminated layer fabric, and the three laminated layer fabric includes a top layer, a middle layer and a bottom layer, wherein the middle layer has one end connected with the top layer and the other end connected with the bottom layer; and the spacer fabric has its thickness determined by a length and a knitted angle of the yarn of the middle layer; when in the knitting process, the length of each yarn of the middle layer is gradually decreased/increased and the knitted angle of each yarn of the middle layer is varied, thereby gradually increasing or decreasing the thickness of the spacer fabric.
