Topological Modelling of Knitted Structures

Abstract

This chapter presents the fundamental approach of the description of the yarn paths in weft and warp knitted structures using selected key points. For most of the common structural elements, rules for calculation of the coordinates of their key points are defined, depending on the size of the loop, yarn and depending on the neighbor elements. Some problems and disadvantages of the method for specific elements are described. The approach builds the theoretical core of the modern CAD systems for 3D representation of knitted structures. Its efficiency is proven by its implementation in professional software.
