In fact, it is not that the fabrics have been loaded until break but that in almost cases the fabrics are loaded with a certain force and are chronologically deformed. After a time of being loaded, fabric is with no load or smaller loading capacity. This is a common phenomenon during process of manufacturing and using coated fabrics. This article studies the creep and inverse creep deformation of Taffeta Polyamide (PA) and Polyester (PES) fabrics coated by one and two Polyurethane layers (PU). The results show that creep deformation of fabric coated by one layer is better than that of fabric coated by two layers. In order to make coated fabric with high creep deformation, polyester-based fabric should be used. The article gives out the equations to show the chronological relationship between creep and inverse creep deformation of studied fabrics, creep and inverse creep deformation are inversely proportional to loading time according to quadratic hyperbolic rule and directly proportional to loading capacity.
