Abstract

A fastener strip for diapers has a center part that is elastic in the longitudinal direction of the strip when the fastener strip is pulled, a non-elastic end part to which a hook element is attached, and a non-elastic connector part for attachment to a diaper. The end part and the connector part are attached to the center part. The center part has a layer of an elastic spun-bonded non-woven fabric, which possesses preferred stretching properties in the longitudinal direction of the strip. The spun-bonded non-woven fabric is made of filaments that have a filament core of a thermoplastic elastomer and a filament mantle of a non-elastic thermoplastic polymer, stretched by means of stretching the spun-bonded non-woven fabric.
