Abstract
A nonwoven laminate material for mechanical closure systems, method for its production, and its use. The multi-layer nonwoven fabric laminate material has at least one layer of a polyolefin endless filament nonwoven fabric having a maximum tensile strength in the machine running direction that is at least as great as crosswise to that direction, and made up essentially of fibers having a titer of less than 4.5 dtex, as well as a second layer of a nonwoven fabric that is bonded to the first layer, which includes a sheet of crimped staple fibers made of polyolefins, and whose crimped fibers are coarser than the fibers of the nonwoven fabric of the first layer. The at least two nonwoven fabric layers are bonded to one another at the common interface by bonding in the form of a pre-determined pattern. With this laminate, it is possible to produce diapers that are also suitable for adult incontinence patients, which have a mechanical closure system, e.g., a Velcro.TM. closure.
