Purpose In this paper, special attention is focused on the study of the relaxation phenomena of fabrics containing elastane yarn. Design/methodology/approach For this purpose, the relaxation phenomena of wound fabric under constant deformation, as the consequence of accumulated stress during winding, were analysed. Maxwell's model and the modified standard linear solid model are used for explaining the relaxation. Findings The results of the study of the relaxation phenomena of fabrics containing elastane yarn show a close connection between stress relaxation under constant deformation in the fabric roll and the degree of deformation with manual unwinding. Expert knowledge of the relaxation phenomena in fabrics containing elastane yarns has a big influence on explaining the problem of dimensional changes and instability in such fabrics. Originality/value A better understanding of the relaxation phenomena in fabrics containing elastane yarns.
