Abstract: A polymer electrolyte membrane, a method for manufacturing the same, and a membrane electrode assembly containing the polymer electrolyte membrane are disclosed. The polymer electrolyte membrane includes: a fluorine-based support containing a plurality of pores due to polymer microfibrillar structures; a hybrid porous support placed on one side or both surfaces of the fluorine-based support and comprising nanowebs obtained by integrating nanofibers into a nonwoven fabric containing a plurality of pores; and ion conductors with which the pores of the porous support are filled. The polymer electrolyte membrane can reduce hydrogen permeability while being excellent in both durability and ion conductivity.

Abstract: The present disclosure relates to a method for preparing a non-woven fabric which improves impregnation and release properties of a fabric softener in the non-woven fabric in order to apply the non-woven fabric to a dryer sheet (sheet-type fabric softener). When increasing porosity and specific surface area in a non-woven fabric made of two-component blended polyester long fibers, impregnation and release rate of a fabric softener are improved even when the non-woven fabric is lightened, making it possible to apply the non-woven fabric to a dryer sheet.
