Abstract:
A method for producing a wet-laid nonwoven fabric web includes the following steps: providing a fibrous web of industrially generated inorganic fibers, or fibers from synthetically generated polymers, and thermally drying the fibrous web in an alternating manner by infrared radiation and hot air, in order for the nonwoven fabric web to be generated.
