摘要： The present invention provides nanometer-sized fibers that are produced by an electrospinning method with use of a spinning solution for electrospinning, said spinning solution being environmentally friendly and taking the effects of an organic solvent on the human body into consideration. The fibers are formed from a resin that contains a silicone-modified polyurethane resin which is a reaction product of (A) a polyol, (B) a water dispersant, (C) an active hydrogen group-containing organopolysiloxane represented by formula (1) R1R2R3SiO(SiR2R3O)nSiR1R2R3  (1) (wherein R1 represents a monovalent hydrocarbon group which may have an oxygen atom in the chain, while having from 1 to 10 carbon atoms and a hydroxyl group or a mercapto group, or a monovalent hydrocarbon group which has a primary amino group or a secondary amino group, while having from 1 to 10 carbon atoms; each of R2 and R3 represents a group that is selected from among an alkyl group having from 1 to 10 carbon atoms, an aralkyl group having from 7 to 10 carbon atoms, an aryl group having from 6 to 12 carbon atoms and a vinyl group; and n represents an integer from 1 to 200), and (D) a polyisocyanate.
