Automatic construction of weave diagram of warp-knitted fabric using positional information on yarn

In this paper, a novel method for the automatic construction of weave diagrams of warp-knitted fabrics using positional information on their yarns is proposed. In this study, the yarn positional information corresponds to a sequence of the center points of the yarn and is obtained by using the yarn tracing method proposed in my previous study. The construction of a weave diagram is based on identifying the stitch type at each stitch of the knitted fabric. For constructing a weave diagram, first, the stitch is detected by determining the points of intersection of the yarns and finding the four points which is related by a certain relationship from them. Then, the types of stitches are identified by verifying the existence of the point of intersection of the yarn with itself and investigating the order of these points of intersection of the lower yarn in the stitch. The validity of the proposed method is experimentally confirmed by using the method along with yarn positional information of a net knitted fabric.
