Abstract (en)
[origin: WO2022263029A1] The invention relates to a filter material for the manufacture of a segment for a smoking article, wherein the filter material is hydroentangled and contains at least 50% and at most 100% cellulose fibres, in each case based on the mass of the filter material, wherein the filter material has a weight per unit area of at least 15 g/m² and at most 60 g/m², wherein the thickness of a layer of the filter material, measured according to ISO 534: 2011 is at least 25 µm and at most 400 µm, and wherein the filter material has a creep tendency in the thickness direction of at most 10%, the creep tendency being the relative decrease in thickness of 5 layers of the filter material, measured according to ISO 534:2011, within 20 s after the start of the thickness measurement.
