PROCESS FOR PRODUCING MICRON AND SUBMICRON FIBERS AND NONWOVEN WEBS BY MELT BLOWING

摘要

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.
