Abstract: An adjustable brassiere metal-free back fastener is formed by molding eyelets and studs on ultrasonically or mechanically pierced fabric tapes composed of polyamide yarn which is partly enfolded in an outer tape ultrasonically welded to the inner tape. No stitching is required in the fabrication of the fastener and because the coupling members and the thermoplastic yarn can be of the same polyamide material, the product can be uniformly dyed.
