COATED PAPER FILTER |
摘要 |
A biodegradable paper substrate and/or biodegradable fiber (including fiber tow) may be coated with cellulose acetate and/or plasticized cellulose acetate for use in a filter material configured for application in a filter of a smoking article. Flocking and/or fibrillation methods may be used to deposit and/or generate a plurality of fibers that may protrude beyond a surface of the biodegradable substrate material. A filter made in accordance with this design may also include non-biodegradable material. |
