Nanotechnology and Respirator Mask
One example of nanotechnology is the use of nanofibers as a performance layer for industrial air filtration applications. To produce a nanofiber layer, an electro-spinning process creates a very fine, continuous, resilient fibre of 0.2 – 0.3 micron in diameter that is then applied to a filtration media substrate material. The nanofibers form a permanent web with very fine interstitial spaces on the surface of the substrate. The web collects dust, dirt and contaminants on the surface of the filter; this offers many benefits over conventional filters built with cellulose, cellulose/synthetic, spun bond, or melt blown commodity filtration media.
