Web comprising fine fiber and reactive, adsorptive or absorptive particulate

摘要

The assemblies of the invention can comprise a fine fiber layer having dispersed within the fine fiber layer an active particulate material. Fluid that flows through the assemblies of the invention can have any material dispersed or dissolved in the fluid react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.

主权项

1. A filter media comprising a substrate and a layer comprising a substantially continuous fine fiber, the fiber having a diameter of about 0.001 to 5 micron, and an active particulate dispersed in the layer, the layer having a thickness of about 1 to 100 times fiber diameter; wherein the active particulate comprises about 0.001 to 10 kg per square meter of the layer; wherein the fine fiber layer is substantially uniform in active particulate distribution on the substrate.
