Abstract

Matériau filtrant perméable à l’air et imperméable aux excrétions aqueuses liquides humaines buccales, nasales et/ou oculaires comprenant au moins une liasse, dite liasse hydrophobe, d’au moins deux feuillets hydrophobes superposés et formés chacun de papier poreux, de grammage inférieur à 30 g/m2, chaque feuillet hydrophobe étant formé de fibres de cellulose, dites fibres de cellulose réticulées, liées entre elles par des liaisons hydrogène et par des liaisons covalentes formées avec au moins un groupement d’atomes de réticulation,caractérisé en ce qu’au moins une partie des hydroxyles desdites fibres de cellulose réticulées non engagés dans des liaisons hydrogène et accessibles aux gaz forment une liaison covalente avec un groupement acyle à chaîne hydrophobe.
