Simulation of fibrous structure and yarns
Result description
This chapter discusses several models which describe the mechanical properties of staple fibre yarns. Starting with definitions of yarns and their structure, a simple model of a yarn is developed. This is then used to describe the packing density of a yarn and the maximum twist it can bear without coiling. The model is then applied to determine the tensile force utilization coefficient. Finally, a theoretical model based on Koechlin's concept is used to determine a suitable yarn twist. Applying Hamburger's theory, a model is described that allows calculation of the mechanical properties (tenacity, breaking strain, etc.) of staple fibre yarns.
