Abstract
A material comprising unique nanofiber layers, and more particularly, this invention relates to a method for creating a material that is made from multiple unique nanofiber layers that can be utilized as filter media among other applications. The nanofiber layers have a plurality of fine fibers with an average diameter of less than 1 micron. In embodiments, the fine fibers are formed from a polymer. The material can be created according to a method in which the fine fiber strands are formed from a polymer melt or a polymer solution. The fine fibers can then be layered on top of one another to form materials such as filter media.
