Abstract
The invention relates to a laminate (1) comprising at least one support element (2), for example a nonwoven fabric, in particular an SMS nonwoven, and at least one nonwoven loop fabric (3), in particular a carded nonwoven, secured to the support element (1), in particular by means of calendaring with the first nonwoven fabric, characterised in that the curve representing the force required to stretch the laminate along a given axis (e.g. the MD axis or the CD axis of the laminate) as a function of elongation, comprises a segment in which, starting from a zero elongation value, the force increases from zero up to a maximum force, corresponding in particular to the rupture of the laminate, and the curve comprises an inflection point (Pi) on said segment.
