Structural deformation dynamic simulation of weft knitted fabric basic stitch

Abstract

To address the current problem of separating the structural and deformation models of weft knitted fabrics’ basic stitch, and to achieve synchronous simulation of the stitch’s structural form and deformation behavior, we studied the structural form and deformation behavior of the basic stitch, including weft plain stitch, rib stitch, and purl stitch. We established a three-dimensional structural model and conducted data analysis, improving the traditional mass-spring model to obtain a deformation model that fits better with the knitted fabric. We then investigated the connection between the structural and deformation models and constructed a correlation model, and used NURBS (Non-Uniform Rational B-Splines) curve application, force analysis, and dynamic solution to study the simulation of the correlation model. Finally, based on computer technology, we achieved dynamic simulation of the structural deformation of weft knitted fabrics’ basic stitch and demonstrated the simulation effect, proving the feasibility of the method and the rationality of the model.
