Study of the Theoretical and Rheological Models for the Mechanical Behaviour of Cotton Core Spun Yarn with Elastane

摘要

This work is the development of tools and powerful models to characterize the dynamometric properties of cotton core spun yarn with elastane starting from the fibre properties composing this yarns (by taking account of the experimental and theoretical results) to find laws of mechanical behaviour starting from different rheological models and from the mechanical requests such as traction and relaxation. These tools will make it possible to analyse and to optimize the composition and the characteristics of produced yarn.
