Torsional Properties of Single Yarn: Part I - Theoretical Model

Abstract

A refined singles yam torsional model was built based on a previously developed singles yam model⁽¹⁾. The initial yam density distribution was found to be a very important yam parameter governing the torsional property of singles yams. Detailed study of the differential volumetric changes within the yam has shown that jamming of the structure is the key factor initiating longitudinal tensile and compressive strains in the fibres. The yam model was summarised in the form of a system of non-linear equations and the solution finding algorithm was presented.
