Abstract

RESUMEN El artículo absorbente (1) de acuerdo con lo divulgado en la presente posee bordes laterales longitudinales (2,3) que se extienden en una dirección longitudinal (L) y bordes extremos transversales frontal y posterior (4,5) que se extienden en una dirección transversal (T). El artículo absorbente (1) comprende una capa superficial permeable a fluidos (8), una lámina posterior (9) y una capa intermedia (19) ubicada entre la capa superficial permeable a fluidos (8) y la lámina posterior (9). La capa superficial (8) posee una parte enfrentada hacia el usuario (8a) que da hacia el usuario durante el uso. La capa superficial (8) es una capa superficial no tejida, fibrosa, unida por circulación de aire que posee un peso base de 14 a 30 g/m2 y una densidad de 20 a 90 kg/m3. La capa intermedia (10) se extiende debajo desde 70 a 100% de la parte enfrentada al usuario de la capa superficial (8a). La capa intermedia (10) y la capa superficial (8) poseen una elongación respectiva a 10 N/50mm. La elongación de la capa intermedia (10) es menor que la elongación de la capa superficial (8).
