Abstract: Based on viscoelastic theory of textile material,the fabric recovery regular pattern was investigated.Under the presumption that the frictional constraint moment was proportional to the bending curvature of the fabric,the fabric was considered as viscoelastic sheet with internal constraint.The theoretical model which consisted of the three-element model in parallel with a sliding element was adopted to study the wrinkle recovery behavior of fabrics.The course of pressing,bending,releasing and recovery were analyzed using the same model,then,the regular pattern equation of wrinkle recovery angle was deduced.Besides,wool and wool/polyester blended fabrics were used as experimental samples and the comparison of the experimental results and theoretical results indicated that the agreement between them was satisfactory.
