Forcespinning Nanofibers: A Practical Synthetic Alternative to Glass Fibers in High Efficiency Filters

摘要

Nonwoven microglass fibers have been used for decades to address high performance material requirements in applications ranging from air filtration to liquid filtration and from acoustic insulation to thermal insulation, among many others. Microglass fibers are favored because their fine fiber diameters (often measuring in the nanoscale at the low end) generate high surface to volume ratios and small pore structures that in turn can be manipulated to create high performance media for these end uses. Furthermore, the glass is thermally and chemically stable so it can with- stand many of the environmental challenges faced by the end product.
