'A Fine Comprising A Polymer And A Crosslinking Agent Or Additive"


Updated 11 months ago

Abstract

The invention relates to a fine fiber having (a) a diameter of 0.001 to 2 microns and (b)after exposure to air at 140°F and 100% humidity, at least 50% of the fiber remains substantially unchanged for hours for filtration purposes wherein the said fiber is obtained by electrostatic spinning of a polymer solution, the said solution comprising (i) at least one polymer selected from the group consisting of an addition polymer and a condensation polymer; (11) at least one selected from the group consisting of 1 to 40 wt% crosslinkmg agent, and 2 to 25 wt.% of an additive comprising a resinous material having a molecular weight of 500 to 3000 and an aromatic character, wherein the additive is miscible in the polymer
