Abstract:
1. A method of making a textile web from which can be punched elastically stretchable diaper closure elements that each comprise an inelastic and reinforced attachment region for securing a closure component and an adjacent elastic stretch region, the method comprising: inserting a plurality of pairs of elastic film strips of an elastically stretchable polymer between two cover layers of nonwoven with the film strips parallel and spaced laterally from one another; inserting between each pair of elastic film strips a strip of a reinforcement film that has a support layer and an outer layer of polyethylene on at least one side between the cover layers with each reinforcement-film strip overlapping each of the respective elastic film strips at a respective overlap region; bonding the reinforcement-film strips to the elastic film strips in the overlap regions; and bonding the nonwoven cover layers to the reinforcement film strips by ultrasonic or thermal welding, the cover layer bonded to the outer polyethylene layer of the reinforcement film is itself composed of bicomponent fibers that have a fiber core of polypropylene and a fiber sheath of polyethylene, the support layer of the reinforcement film being composed of a polymer that has a higher melting point than the polyethylene of the outer layer.
