A zone treated spunbonded/meltblown/spunbonded (SMS) or spunbonded/spunbonded (SS) fabric laminate (2') that combines the separate functions of the topsheet and cuff in one component of an absorbent article. The SMS fabric laminate is treated with surfactant to form one or more hydrophilic zones (A, B or C). The untreated areas of the fabric laminate remain hydrophobic and perform the function of the cuff. The fabric laminate is treated with surfactant on both sides using a foam applicator. 'The application of foam produces sharp transitions (80) between the hydrophilic and hydrophobic zones.
La présente invention concerne un stratifié textile (2') de type SMS (filé-lié / fondu-soufflé / filé-lié) ou SS (filé-lié / filé-lié) à zones traitées et qui combine les fonctions de voile supérieur et de bourrelet dans le cas d'un article absorbant. Le traitement du stratifié textile SMS est un traitement par un agent tensio-actif tendant à constituer une ou plusieurs zones hydrophiles (A, B ou C), les zones non traitées du stratifié textile restant hydrophobes de façon à remplir les fonctions de bourrelet. Le traitement du stratifié textile au moyen de l'agent tensio-actif se fait recto-verso avec un applicateur à mousse. L'application de mousse donne des transitions nettes (80) entre les zones hydrophiles et les zones hydrophobes.
