Abstract: The invention relates to a polymeric fabric comprising an outer functional layer having hydrophobic and oleophobic characteristics made of a first compound, and a second functional layer having hydrophobic characteristics made of a second compound, wherein the first and the second compound differ from each other. Further the outer functional layer at least partly coats the second layer. Additionally, the invention relates to a method of producing a polymeric fabric and an apparatus for producing a polymeric fabric.

Abstract: The invention relates to a method for producing a carrier layer with a hydrophilic polymeric nanocoating wherein a polymeric carrier layer is produced with filaments of polymer material(s). Further the hydrophilic polymer nanocoating is applied by means of a low pressure plasma polymerization process using organic precursor monomers onto the polymeric carrier layer and/or composite membrane. Additionally, the invention relates to a carrier layer with a polymeric hydrophilic nanocoating.

Abstract: The invention relates to a composite for an acoustic component having at least one carrier layer and an electrospun membrane which is arranged on the at least one carrier layer, wherein the electrospun membrane is formed of superimposed fibers while a pore structure is being designed. The pore structure of the composite is designed such that the composite has a water column of at least 1 m and an air permeability of 5 L/m2*s. Furthermore, the invention relates to a method for producing a composite for an acoustic component, in which a carrier layer is provided and on the carrier layer a membrane is designed according to the electrospinning method, wherein the membrane is produced of superimposed fibers with a defined pore structure.

Abstract: The invention relates to a composite for a protective vent with at least one carrier layer and an electrospinning membrane, which is arranged on the at least one carrier layer, wherein the electrospinning membrane consists of superimposed fibers lying one above the other, forming a porous structure, whereby the porous structure is designed, whereby the carrier layer comprises a monofilament fabric, a plasma coating is applied both to the electrospinning membrane and to the monofilament fabric of the at least one carrier layer and a bonding is provided that connects the carrier layer and the membrane. Furthermore, the invention relates to an according method for producing the inventive protective vent.
