Spunbond laminate and method of making same

A method of making a spunbond nonwoven laminate, the method comprising the steps of:

• providing a first spunbond nonwoven layer having crimped multicomponent or bicomponent filaments of an eccentric core-sheath configuration and formed by
• a first sheath component forming over at least 20% of a filament circumference a substantially constant thickness, and consisting or substantially consisting of a polyolefin, and
• a second component consisting or substantially consisting of a plastic having a higher melting point than the polyolefin of the first component of the filaments of the first layer
• preconsolidating the first layer with hot air;
• providing a second outermost spunbond nonwoven layer having multicomponent or bicomponent filaments to and formed by
• a first component on an outer surface of the filaments of the second layer consisting or substantially consisting of a polyolefin, and
• a second component consisting or substantially consisting of a plastic having a higher melting point than the polyolefin of the first component of the filaments of the second layer, a polyolefin portion of the first component of the filaments of the second layer being greater than a polyolefin portion of the first component of the filaments of the first layer;
• preconsolidating the second layer with hot air;
• forming the first and second preconsolidated layers into the spunbond nonwoven laminate;
• and
• finally consolidating the spunbond nonwoven laminate formed by the first and second layers with hot air.
