Abstract: The present invention relates to a process for coating a polymer nonwoven comprising the steps of: plasma and/or corona assisted treatment of the surface of the nonwoven to obtain a charged and/or polar surface; and formation of a first coating layer comprising at least one first charged and/or polar species, the first species being a hydrophilic polymer, wherein the overall charge or partial charge facing the nonwoven surface of the first species carries the opposite sign from the average charge introduced to the nonwoven fiber surface in step a).

Abstract: A superhydrophobic coating of a nonwoven material is coated with a spongy mesh structure in the micro and nano ranges.

Abstract: The invention relates to a nonwoven material having elastic properties aligned in one direction, consisting of either one multilayer composite including at least one layer in which fibers or filaments made of an elastic polymer are contained, or of a homogeneous fiber and filament mix in which a portion of the fibers consists of an elastic polymer, wherein in each case a larger part of the fibers or filaments is aligned in a direction under the application of heat which extends transversely to the direction in which the nonwoven material is elastic. The invention furthermore relates to a method for the manufacture of the nonwoven material and to an apparatus to carry out the method.
