摘要：
A multicomponent spunbonded nonwoven is provided which is composed of at least two polymers which form interfaces toward one another, which are produced by at least one spinning machine having uniform spinning nozzle apertures, and which are hydrodynamically drawn, lapped in a sheet-like manner, and bonded, the multicomponent spunbonded nonwoven being composed of different filaments which contain at least two polymers, or it being composed of a mixture of multicomponent filaments and monocomponent filaments which each contain only one of the polymers, the multicomponent filament being composed of at least two elementary filaments and the titer of the individual filaments varying by the number of elementary filaments contained in the filaments.
