Abstract

A textile laminate consists of a nonwoven padding material of low specific volume and of a filament-reinforced nonwoven, the laminate having a total thickness of more than 2 mm. The nonwoven padding material has a raw density of less than 0.025 g/cm.sup.3 and a thickness of 1.6 to 60 mm. The filament-reinforced nonwoven is composed to 10 to 60 g/m.sup.2 of a fleece with a raw density greater than 0.35 g/cm.sup.3 and of 3 to 10 g/m.sup.2 reinforcing filament and is laminated onto the nonwoven padding material.
