Abstract A process for stripping chemically bonded spinning solvent from a solution-spun nonwoven web comprising the steps of providing a nonwoven web comprising solvent-laden polymeric fibers having average fiber diameters of less than about 1 micrometer, and transporting the nonwoven web through a solvent stripping zone wherein infrared radiation irradiates the nonwoven web and a solvent stripping fluid impinges on the nonwoven web in order to reduce the solvent concentration of the fibers to less than about 10,000 ppmw.
