Abstract
A process for producing a polymer nonwoven fabric includes providing a polymer blend of a thermoplastic elastomer and a further thermoplastic material. Fibers are produced from the polymer blend. A nonwoven semifinished product is formed from the fibers. In order to then produce the polymer nonwoven fabric, a volume increase is produced by mechanical stretching of the nonwoven semifinished product and subsequent relaxation. A process for using a semifinished nonwoven product and a process for using a polymer nonwoven are also provided.
