Abstract: Nonwoven multilayer structures having at least two nanofiber layers are described herein. The nonwoven multilayer structure may have two nanofibers layers that have different properties from each other, such as fiber diameter. One nanofiber layer may be produced by an electrospinning process, while another nanofiber layer may be produced by a melt blown process.
