Title (EN) TREATED MEMBRANE FOR FRAGRANCE DELIVERY
(FR) MEMBRANE TRAITÉE POUR DISTRIBUTION DE PARFUM
Abstract:
(EN) A treated vapor permeable microporous membrane includes: a microporous membrane having a first side and a second side opposite the first side. The membrane includes a thermoplastic organic polymer having a polyolefin. The membrane defines a network of interconnecting pores communicating substantially throughout the membrane. The treated membrane further includes finely divided, particulate filler distributed throughout the membrane and a first hydrophobic/oleophobic material over at least a portion of the first side. A method of preparing the treated vapor permeable microporous membrane is also disclosed.
(FR) Une membrane microporeuse perméable à la vapeur traitée comprend : un membrane microporeuse ayant un premier côté et un second côté opposé au premier côté. La membrane comprend un polymère organique thermoplastique ayant une polyoléfine. La membrane définit un réseau de pores d'interconnexion communiquant sensiblement dans toute la membrane. La membrane traitée comprend en outre une charge particulaire finement divisée distribuée à travers la membrane et un premier matériau hydrophobe/oléophobe sur au moins une partie du premier côté. L'invention concerne également un procédé de préparation de la membrane microporeuse perméable à la vapeur traitée.
