Viscoelastic Behaviour and Microstructural Modifications in Acrylic Fibres and Yams as a Function of Textile Manufacturing Processing Conditions

Abstract

Tensile tests on acrylic yarns and fibres extracted from various steps of textile processing reveal mechanical and thermal modifications due to the manufacturing operations. To examine this, viscoelastic modelling based on mechanistic models for fitting experimental data of tensile tests were investigated. Crystalline/amorphous distribution was assessed by the differential solubility technique, and the models account for changes in property values due to microstructure modifications.
