Bulky nonwoven fabric with enhanced compressibility and recovery

Nonwoven fabric comprising at least one layer, said layer comprising continuous filaments,

• the continuous filaments comprising at least a first polymeric material and a second polymeric material, the second polymeric material having a melting point that is lower than that of the first polymeric material,
• wherein the second polymeric material extends in a longitudinal direction of the continuous filaments and forms at least parts of the surfaces of the continuous filaments and
• the at least one layer of continuous filaments comprises filament-to-filament bonds formed of the second polymeric material, wherein all components of the continuous filaments are arranged across the cross-section of the continuous filaments in a non-crimpable configuration and the nonwoven fabric has a structural softness of at least 80 (m4mm2g-2), wherein
