The Reason of Wrinkles of Laminated Fabrics The laminated fabrics are manufactured by laminating one or several type’s fabrics. Since the tensions of the two kinds of fabrics are not the same on laminating process, one material tension is too high and other one fabric tension is too small. After lamination, the material with bigger tension will shrink, and the material with small tension on the other side will shrink, so cause relative displacement and wrinkle.
