Zusammenfassung:	The present invention is directed to novel face masks, which include a spunbonded/meltblown/spunbonded (SMS) laminate. The face masks of the present invention may include other layers, in addition to the SMS layer, such as an electret meltblown layer, a spunbonded layer, a wet-laid layer or a second SMS laminate. In one embodiment, the face mask includes an outermost SMS layer, an intermediate electret meltblown layer, and an innermost layer in the form of a spunbonded layer, a wet-laid layer or a second SMS laminate. L'invention porte sur de nouveaux masques faciaux faits d'un laminé SMS (filé-lié/fondu-soufflé/filé-lié), pouvant éventuellement comporter d'autres couches additionnelles telles qu'une couche d'électret fondu-soufflé, de fondu-lié, de non tissé voie humide, ou une deuxième couche de laminé SMS. Dans l'une de ses exécutions, le masque facial comporte une couche extérieure de laminé SMS, une couche intermédiaire d'électret fondu-soufflé, et une couche intérieure constituée soit de filé-lié, soit de non tissé voie humide, soit d'un deuxième laminé SMS.
