  • Publication number: 20200016013
    Abstract: A spunbond nonwoven web for an acquisition/distribution layer, the web comprising a first layer (1) of filaments, wherein the first layer (1) consists of continuous crimped bi-component filaments of an eccentric core/sheath structure, the filaments having a diameter in the range of 15 to 35 microns and exhibiting at least 3 crimps/cm, a second filament layer (2) arranged in direct contact on the first layer (1), wherein the second layer (2) of filaments comprises continuous crimped bi-component filaments of an eccentric core/sheath structure, the filaments having a diameter, which is smaller than the diameter of the filaments in the first layer (1) and which is in the range of to 20 microns and exhibiting at least 3 crimps/cm.
