Abstract
Abstract Textile fabric which has residual inner stresses can be uniformly continuously relaxed by a method in which the fabric is heated by steam or hot water and subjected to a mechanical impact such as vibration or jumping, and at the same time, carried along a treating surface owing to the effects of the heating fluid and the mechanical impact. An apparatus for carrying out the method comprises a carrying plate for fabric to be relaxed, a heating medium jetting means corresponding to the carrying plate, and an impact-exerting mechanism. By the method and the apparatus, the textile fabric can be uniformly and continuously relaxed without any fixed wrinkles, and results in suitable handling, bulkiness and dimensional stability.
