摘要：
Elastic laminate for closure straps or elastic waistbands in diapers, which is composed of a coextruded elastic sheet, which has an elastomeric support layer and at least one covering layer, and at least one textile outer layer based on a fabric non-woven, the covering layer having a small layer thickness, compared to that of the support layer, and the outer layer having been applied by lined on the covering layer, and the covering layer being composed of a material elastomer which, like the elastomeric support layer, unlike thermoplastic materials, after a tensile stress at room temperature, has a pronounced elastic proportion, and contains additives for the modification of surface properties, characterized in that the elastomeric material for the covering layer and the support layer is composed of a thermoplastic elastomer, taken from the assembly of block copolymers, elastomeric polyurethanes, or mixtures of these elastomers, because the material of the nonwoven fabric of the outer layer is composed of non-elastomeric fibers that, after stretching, have a significant permanent deformation, and because The outer layer has an elongate region, which has been produced by a transverse stretch of the laminate in a meandering slit between two profiled rollers engaged with each other.Estratificado elástico para cintas de cierre o cinturillas elásticas en pañales, que se compone de una lámina elástica coextrudida, que tiene una capa de soporte elastómera y por lo menos una capa de cubrimiento, y por lo menos una capa externa textil a base de una tela no tejida, teniendo la capa de cubrimiento un espesor de capa pequeño, en comparación con el de la capa de soporte, y habiendo sido la capa externa aplicada por forrado sobre la capa de cubrimiento, y componiéndose la capa de cubrimiento a base de un material elastómero que, al igual que la capa de soporte elastómera, al contrario que los materiales termoplásicos, después de una solicitación por tracción a la temperatura ambi
