Abstract
A 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 composition such that the general structure of the fiber has a polymer core surrounded by at least a layer of the resinous aldehyde composition.
Claims22

(canceled)
A fine fiber comprising a core phase and a coating phase;
- wherein the core phase comprises nonreactive polymer and the coating phase comprises a self-crosslinked resinous melamine-aldehyde composition;
- wherein the fine fiber is prepared from a resinous melamine-aldehyde composition in an amount of greater than 20 parts by weight per 100 parts by weight of the nonreactive polymer.
