Abstract
Official abstract text for this publication.
The present disclosure provides a unique method of making a fine fiber that is formed from a composition including an epoxy and a polymer component including a 4-vinyl pyridine-containing polymer. The present disclosure also provides a unique method of coating a fine fiber with a composition including an epoxy and a polymer component including a 4-vinyl pyridine-containing polymer. The present disclosure further provides fine fibers wherein the entirety of the fiber is formed from a composition including an epoxy and a polymer component including a 4-vinyl pyridine-containing polymer. Also provided are filter media and ter substrates including the fine fibers.
First claim
Opening claim text (preview).
1 . A method of making a fine fiber, the method comprising: providing a polymer component, wherein the polymer component comprises a 4-vinyl pyridine-containing polymer; providing a solvent that does not complex with 4-vinyl pyridine; providing an epoxy, wherein the epoxy is at least difunctional; and combining the polymer component, the solvent, and the epoxy to form a composition and forming a plurality of fibers out of the composition, such that the entirety of each fiber is prepared from the composition. 2 .- 20 .
