A nonwoven fabric has a volume-giving material, in particular fiber balls, down and/or fine feathers, and has a maximum tensile strength, measured according to DIN EN 29 073 at a mass per unit area of 50 g/min at least one direction, of at least 0.3 N/5 cm, in particular of 0.3 N/5 cm to 100 N/5 cm.

Volume nonwoven fabric

A method for producing a volume nonwoven fabric includes the steps of: (a) providing a nonwoven fabric raw material, containing fiber balls and binder fibers; (b) providing an air-laying device, which has at least two spiked rollers between which a gap is formed; (c) processing the nonwoven fabric raw material in the device in an air-laying method, the nonwoven fabric raw material passing through the gap between the spiked rollers, fibers or fiber bundles being pulled from the fiber balls by the spikes; (d) laying on a laying apparatus; and (e) thermally bonding so as to obtain the volume nonwoven fabric.
