Abstract: A filter comprising a nanofiber nonwoven product is disclosed which comprises a polyamide with a relative viscosity from 2 to 330, spun into nanofibers with an average diameter of less than 1000 nanometers (1 micron). In general, the inventive products are prepared by: (a) providing a polyamide composition, wherein the polyamide has a relative viscosity from 2 to 330; (b) melt spinning the polyamide composition into a plurality of nanofibers having an average fiber diameter of less than 1 micron, followed by (c) forming the nanofibers into the product.

Abstract: Nonwoven multilayer structures having at least two nanofiber layers are described herein. The nonwoven multilayer structure may have two nanofibers layers that have different properties from each other, such as fiber diameter. One nanofiber layer may be produced by an electrospinning process, while another nanofiber layer may be produced by a melt blown process.

Abstract: A sound absorbing multi-layer composite for a vehicle that reduces sounds along an acoustic path is configured with a non-foam polymeric layer and a face layer for dissipating sound energy. Also, the face layer may be made of a nonwoven polymer comprising at least 60% of a polyamide containing an aliphatic diamine having 6 or more carbon atoms and an aliphatic diacid having 6 or more carbon atoms. The weighted overall average fiber diameter of the composite is from 2 microns to 25 microns.
