Fabrication method of polyamide nanofiber non-woven fabric using a radiation technique and crosslinked nanofiber non-woven fabric thereby

摘要

The present invention relates to a method for producing a polyamide-based nanofiber nonwoven fabric using radiation and to a crosslinked nanofiber nonwoven fabric produced thereby. Preparing a spinning solution by dissolving a polymer in a solvent (step 1); preparing a final spinning solution by mixing a crosslinking agent with the spinning solution prepared in step 1; Preparing the final spinning solution prepared in step 2 into a nanofiber nonwoven fabric through an electrospinning process (step 3); and crosslinking by irradiating the nanofiber nonwoven fabric with radiation (step 4). Provided are a method for producing a fibrous nonwoven fabric. The method of manufacturing the nanofiber nonwoven fabric of the present invention is excellent in reducing the water absorption rate of the nonwoven fabric, increasing the thermal properties, increasing the crystallinity and mechanical properties even though the fiber is produced by the electrospinning method. There is an effect that can be applied to a wide range of applications.
