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.

Abstract: The invention relates to non-woven fabrics comprising threads not produced with the spun-bonding method, for example made of non-melt spinnable thread-forming materials. The use of these fibers, optionally in combination with filaments produced using the spun-bonding method, allows the production of novel non-woven fabrics with novel property combinations. The production can be carried on conventional spun-bonding equipment, wherein part of the extruding devices are used as conveyors for the threads not produced with the spun-bonding method.

Abstract: A stretching device and method of manufacturing stretched synthetic filaments (2, 3) includes a spinning device (1) and a pneumatic drawing-off device (10). A heating device (5) is situated between the spinning device (1) and the drawing-off device (10) which heats the filaments (2, 3) to a temperature between their glass-transition temperature and their melting temperature.
