Abstract: Sterile nonwoven fabric is produced by impregnating a textile sheet of nonwoven fabric with an aqueous dispersion containing a polyurethane, then drying the fabric and irradiating it with gamma rays. Independent claims are also included for (a) sterile nonwoven fabric obtained by this process; (b) articles made from this fabric for medical applications or for use as hygiene products, especially sterile packed articles; (c) a process for the production of sterile nonwovens in which an article made of the fabric is packaged before irradiation, in a pack which is impervious to microorganisms.
