    Abstract: Nonwoven materials and products comprising nonwoven materials are provided that include a substrate comprising fibers and nanoparticles incorporated into at least a portion of the substrate. A nonwoven material comprises a substrate comprising fibers and having a first surface and an opposing second surface, and nanoparticles disposed within the substrate at least between the first and second surfaces. The density of the nanoparticles decreases from the first surface towards the second surface, or a higher density of nanoparticles is disposed on the two surfaces as compared to the middle section of the substrate. This density gradient formed by the nanoparticles improves the performance characteristics of the material for a number of different applications. For example, the nanoparticles increase the overall surface area within the substrate, which may increase its filtration efficiency and allow for the capture of submicron contaminants without significantly compromising other factors, such as pressure drop across the filter.

    Abstract: Filter media, methods of manufacturing and filters are disclosed. The filter media comprises thermally splittable fibers to reduce the fiber size of at least some components of the fibers within the filter media. This reduced fiber size increases the overall efficiency of such filters at capturing contaminants, particularly those contaminants having a size range of about 0.1 to about 10 microns, without compromising other important characteristics of the filters. A filter media comprises one or more bicomponent fibers each having first and second components. The first component comprises a thermoplastic elastomer material and a thermoplastic material and has a higher shrinkage ratio/percentage/rate than the second component such that at least a portion of the first component separates from the second component upon the application of heat or thermal energy to the fiber.

    Abstract: Provided herein are absorbent materials for wound dressings, a bandage comprising an absorbent pad and methods for making the absorbent pad. The absorbent pad comprises a first layer comprising a polymer, such as an extruded apertured polymeric film, and a second layer thermally bonded to the first layer. The second layer comprises at least one thermally bondable fiber, such as a bicomponent fiber having at least a first material with a higher melting point than a second material. The first and second layers are bonded to each other such that the three-dimensional structure and the inherent porosity of the polymeric mesh is substantially maintained, resulting in a bilayer absorbent pad with increased absorbency and enhanced wicking capabilities.
