Abstract
This invention is a method for fabricating fibers by melt-blowing a melt of a molecularly self-assembling material, the melt being at a temperature of from 130° C. to 220° C., thereby forming a fiber set having a distribution of fiber diameters wherein at least 95% of the fibers have a diameter of less than about 3 microns. The invention further comprises collecting the fiber set so as to form a fibrous non-woven web.
