Abstract: The design methods of the double-layer yarn-dyed fabrics which are connectcd by the connection points is focused on the arrengement of the connection points. Based on the analysis of the structure of the knotting up and down double-layer yarn-dyed fabrics, it is researched the design methods of this kind of fabrics with different distribution of the connection points. When the connection points are highly concentrated and concealed, the upper & lower layers are close connected, then two-faced fabric can be formed; When the connection points are sparsely arranged and relatively concealed, the two layers are partly separateted, the exterior of the fabric is determinged by the yarns of the upper layer; When the connection points form the mini-figures on the fabrics surface, a unique double-layer yarn-dyed small jacquard fabric comes into being.
