Title
(EN) AEROSOL-GENERATING ARTICLE HAVING BIODEGRADABLE FILTRATION MATERIAL
(FR) ARTICLE DE GÉNÉRATION D'AÉROSOL CONTENANT UN MATÉRIAU DE FILTRATION BIODÉGRADABLE
Abstract
(EN)
There is provided an aerosol-generating article (10) comprising an aerosol-generating substrate (12) and a filter (14) in axial alignment with the aerosol-generating substrate (12). The filter (14) comprises at least one segment of filtration material formed of one or more sheets of a fibrous paper-like material. The fibrous paper-like material comprises a combination of hydrophobic fibres and hydrophilic fibres such that the fibrous paper-like material has a water contact angle as measured in accordance with TAPPI/ANSI T 558 om-15 greater than 90 degrees. Further, the fibrous paper material has a biodegradability in aqueous medium as tested in accordance with ISO 14851 (2005) of at least 90 percent of the maximum degradation of a cellulose reference item within 56 days of testing. In addition, the hydrophobic fibres comprise hydrophobic viscose fibres.

La présente invention concerne un article de génération d'aérosol (10) comprenant un substrat de génération d'aérosol (12) et un filtre (14) dans un alignement axial avec un substrat de génération d'aérosol (12). Le filtre (14) comprend au moins un segment de matériau de filtration formé d'une ou de plusieurs feuilles d'un matériau de type papier fibreux. Le matériau de type papier fibreux comprend une combinaison de fibres hydrophobes et de fibres hydrophiles de telle sorte que le matériau de type papier fibreux a un angle de contact avec l'eau tel que mesuré conformément à TAPPI/ANSI T 558 om-15 supérieur à 90 degrés. En outre, le matériau de papier fibreux a une biodégradabilité dans un milieu aqueux tel que testé conformément à la norme ISO 14851 (2005) d'au moins 90 pour cent de la dégradation maximale d'un article de référence de cellulose dans 56 jours de test. De plus, les fibres hydrophobes comprennent des fibres de viscose hydrophobes.
