| abstract |
A composite web of elastomeric nanofiber and at least one type of active particle is provided. Different types of active particles are easily incorporated into one nanofiber layer. Alternatively, multiple layers of web can be provided, wherein the same or different active particles can be incorporated in each layer. Active particles can absorb, adsorb, or react, or a combination of sorb and react with electromagnetic, chemical, and/or biological agents. The composite webs can form effective barrier layers toward a variety of materials. The composite webs can be provided on a substrate. When the substrate is a fabric, the composite webs of the invention can be incorporated into a protective garment. Protective garments of the invention are lightweight, soft, have good drape, and the active particles are durably held in place during the flexing, stress, and strain commonly encountered in garment applications. |
