Abstract

See full text

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.
