The present disclosure provides composite materials comprising nettings, mattings or meshes thermally bonded to outer layers of nonwoven fibers that may be configured for use in a variety of applications and products. A composite material comprises a first layer of netting comprising intersecting strands and a second layer in contact with the first layer.

Thus, the composite material will swell and absorb heat, while still remaining adhered to the substrate it is designed to protect.

NONWOVEN MATERIALS AND PRODUCTS CONTAINING NONWOVEN MATERIALS
Nonwoven materials and products comprising nonwoven materials are provided including 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.

Filter media and filters, such as air filters, face masks, gas turbine and compressor air intake filters, panel filters and the like, are provided that include high linear density fibers and nanoparticles dispersed throughout at least a portion of the filter media. A filter includes a filter media comprising a substrate of fibers having a linear density of greater than about 3 denier, and nanoparticles disposed within the substrate. The larger linear density fibers provide more open space or pores within the filter media, allowing for a greater density of nanoparticles to be dispersed therein. This improves the overall efficiency of the filter. The three-dimensional distribution of nanoparticles within the filter also provides resistance against complete blockage of a particular portion of the filter, thereby reducing the overall pressure drop across the filter.

In addition, the filters disclosed herein are capable of withstanding rigorous conditioning, which allows the filter to achieve the same level of filtration performance throughout the lifetime of the filter.

The system further includes a second dispersion device for dispersing nanoparticles through the first surface of the substrate such that the nanoparticles are disposed within the substrate between the first and second surfaces. The binding agent facilitates the bond between the fibers and the nanoparticles to retain the nanoparticles within the internal structure of the substrate. In addition, facilitating this bond provides a more uniform distribution of the nanoparticles throughout the substrate, which improves the performance characteristics of the material.
