Creep and Creep Recovery Behaviour of Textile Fabrics and their Fused Systems

Abstract

Creep and creep recovery behaviour of two suit fabrics, and two fusible interlinings as well as their binary systems are investigated under the different constant loads. The total elongation is assumed to be comprised of elastic, viscoelastic, instantaneous irreversible and progressively developing irreversible (“plastic”) components. Referring to this the mechanical model, which included generalized Voigt elements possessing regular discrete retardation time spectra was proposed for theoretical analysis of the processes. The model units representing irreversible components of elongation have fixers. Good correspondence between theoretical and experimental results proves that the proposed model is appropriate for the analysis of the time-dependent mechanical behaviour of the textile fabrics and their fused systems.
