Abstract

L'invention concerne un produit stratifié absorbant, jetable, à usage unique (10), qui contient une ou plusieurs couches (12, 22) de matière hydrophile filée en fusion reliée à un film respirant (14). La couche de tissu filé en fusion (12, 22) peut contenir au moins un tissu filé-lié, un tissu obtenu par fusion-soufflage ou un autre non-tissé qui est rendu hydrophile avant d'être relié au film (14). Les filaments ou microfibres des tissus filés-liés ou des tissus obtenus par fusion-soufflage peuvent contenir intérieurement ou superficiellement un adjuvant hydrophile. Bien qu'il soit transpirant, le film (14) des champs opératoires confère au produit stratifié une résistance à la pénétration des liquides et des virus.
