ABSORBENT PRODUCT Russian patent published in 2020 - IPC D04H3/14 

FIELD: hygiene.

SUBSTANCE: multilayer nonwoven material (10) according to the present invention has multilayer structure (13) of fibrous layers, which include thermoplastic fibres. Multilayer structure (13) has first surface (10a), which is surface of multilayer nonwoven material (10), and second surface (10b) as another surface of multilayer nonwoven material (10). First surface (10a) is formed by hydrophobic first layer (11). Hydrophilic second layer (12) is located on the side of first layer (11) closer to second surface (10b). Multilayer structure (13) includes interlayer fused parts (16), which are thinner than parts peripheral with respect to interlayer fused parts (16), and in which layers forming multilayer structure (13) are fused to each other. First layer (11) includes interfibre fused parts (17), which are thinner than parts peripheral with respect to interfibre fused parts (17), and in which constituent fibres of first layer (11) are fused to each other, besides interlayer fused parts (16). First surface (10a) has a share of area of fused parts which exceeds a share of area of fused parts of second surface (10a).

EFFECT: multilayer nonwoven material (10) having this structure has a high capacity for absorption of a body fluid, such as sweat and urine.
