Title:
FIBERS CONSISTING OF THERMOSETTING POLYAMIDE RESIN COMPOSITION, NONWOVEN FABRIC, AND PROCESS FOR PRODUCTION OF SAME
Document Type and Number:
WIPO Patent Application WO/2011/052175
Kind Code:
A1
Abstract:
Disclosed are: fibers which consist of a thermosetting polyamide resin composition comprising (a) a polyamide having phenolic hydroxyl groups and (b) an epoxy resin having two or more epoxy groups in one molecule; nanofibers which consist of the resin composition and which are produced by electrospinning; a nonwoven fabric obtained by subjecting a deposit composed of the nanofibers to heat treatment; a process for the production of the nanofibers by electrospinning; and a thermosetting polyamide resin composition for fibers. The nonwoven fabric can be obtained merely by heat-treating a nanofiber deposit formed by electrospinning using the resin composition. In the nonwoven fabric, the nanofibers have been bonded to each other through thermosetting. Therefore, the nonwoven fabric is characterized by excellent mechanical strengths, excellent resistances to heat and chemicals, and high strength.
