摘要：
The present invention relates to a fiber comprising a heat curable polyamide resin composition containing both a) a phenolic hydroxy group-containing polyamide and b) an epoxy resin having two or more epoxy groups in one molecule, a nanofiber comprising said resin composition obtained by electrospinning method, a nonwoven fabric obtained by applying heat treatment to a laminate of said nanofiber, a method for producing said nanofiber by electrospinning method and a heat curable polyamide resin composition for fiber. A nonwoven fabric can be obtained only by subjecting a deposit of the nanofiber obtained by electrospinning method to heat treatment, nanofibers in the obtained nonwoven fabric are bonded to each other by heat-curing, and the nonwoven fabric has such characteristics that its mechanical strength, heat resistance and chemical resistance are excellent and that it has a high strength.
