Abstract: A microfiber nonwoven composite has a first and a second fiber component arranged in form of alternating layers, wherein—at least a first layer A has the first fiber component in form of composite filaments melt-spun and deposited as a nonwoven fabric which are at least partially slit and solidified to form elementary filaments having an average titer of less than 0.1 dtex, preferably between 0.03 dtex and 0.06 dtex,—at least one layer B is arranged over layer A, wherein the layer B has the second fiber component in form of fibers deposited and solidified as a nonwoven fabric having an average titer of from 0.1 to 3 dtex—at least one second layer A is arranged on layer B.
