Abstract
A fine fiber can be made having a structure with an axial core and a coating layer. The fiber can have a polymer core and one or two layers surrounding the core. The fine fiber can be made from a polymer material and a resinous aldehyde (e.g., melamine-aldehyde) composition such that the general structure of the fiber has a polymer core surrounded by at least a layer of the resinous aldehyde composition.
