Weft Yarn Interlacement Modelling for 3D Profiled Structures

Spackman, George; Brown, Louise; Turner, Thomas

Abstract

Currently, generation of 3D woven T-joint models with complex weave geometries, using TexGen software, is a manual process. One of the main challenges to automatic generation of these textiles is the order in which the weft yarns interlace within the bifurcation region. This paper will demonstrate a method for predicting the order, based on the pattern draft and the information contained within it such as the direction of weft insertion and the beating action of the loom. The path of the entangling weft yarns and the yarn cross section orientation can then be modelled. Finally, a geometric transformation is be applied to simulate the opening of the flanges so that the final model reflects the T-shaped profile.
