Item Metadata only Advances in CAD simulation of textile yarns(Research Journal of Textile and Apparel, 2011-02-02) Grishanov, S. A.; Siewe, Francois; Cassidy, T.A project aimed at the 3D simulation of textile yarns from technical specifications was begun in 1993 and attracted support from both industry and research councils to enable the formation of a multi-national team of researchers to come together in the UK. Considerable progress has been made particularly in the simulation of knitting yarn and plain knit fabric. In recent times the team has tackled the problem of simulating mixture coloured yarns sometimes called melange. This has necessitated a more complicated model of yarn structure based on queuing theory which is outlined at the end of the paper. References are provided for readers who wish to learn more of the various theories and models that have been used throughout the course of this project.Item Metadata only An application of queuing theory to modelling of melange yarns. Part I: A queuing model of melange yarn structure.(SAGE, 2009-11-01) Siewe, Francois; Grishanov, S. A.; Cassidy, T.; Banyard, GeoffreyA queuing model of staple fiber yarn is presented that enables the modeling and a better understanding of fiber migration in a yarn. The model provides a fine yarn structure where the migrational behavior of fibers is associated with the behavior of customers traveling across an open network of queuing systems to get services. Based on this analogy, the underlying mathematical foundation of the queuing theory is used for the modeling of yarn structure and properties. The model uses yarn technical specifications including yarn linear density and twist level, fiber linear density and length distribution, together with specific parameters such as fiber packing density distribution and migration probabilities. The model can be used for modeling a wide range of structurally different yarns; examples include marl, mottle and melange yarns, yarns with different levels of hairiness, and yarns produced by various spinning systems. The model can be used for 3D simulation of yarns in computer-aided design systems for textile design and for the prediction of mechanical properties of yarns.Item Metadata only A comparative study of the characteristics of fibre-flax (Linium usitatissimum)(2002-04) Grishanov, S.
