A NONLINEAR VISCOELASTIC MODEL FOR DESCRIBING FABRIC WRINKLE RECOVERY BEHAVIOUR

The main objective of this paper is to study and model the relaxation behaviour of fabric wrinkle recovery. Based on the viscoelasticity theory of textile materials and in order to describe the viscoelastic behaviour of wrinkle recovery, we proposed a rheological model and we studied the correlation between experimental and theoretical creep-recovery curves. The creep-recovery equation of Burgerâ?™s model describes well the relaxation behaviour of wrinkle recovery according to the time. The proposed nonlinear viscoelastic model permitted us also to evaluate the components of elastic, viscoelastic and plastic deformation of the different wrinkled fabrics.
