Abstract

Textiles industry Weft-knitted textiles
Knitting is a method of producing textiles that has been employed by humans for over a millennium and is increasingly important to many industries. Despite their long-time existence and significant capabilities, computational modeling, simulation, and design tools have been underutilized for tex- tiles in general, limiting the ability of knitted textiles to be widely deployed and to reach their full industrial potential. These computational tools require a robust representation and ecient evaluation of the spatial, material and physical properties of textile structures. This dissertation proposes a process-oriented representation, TopoKnit, that defines a foundational data structure for representing the topology of weft-knitted textiles at the yarn scale. Process space serves as an intermediary between the machine and fabric spaces, and supports a concise, computationally efficient evaluation approach based on on-demand, near constant-time queries. This work defines the properties of the process space, designs a data structure, and implements topological queries for knitted fabrics. The topological representation enables a number of other capabilities, namely integrity and stability analysis, and stitch command generation for the inverse design of specified topological structures. TopoKnit's data may also be transformed into a knot diagram representation for further downstream topological analysis.
