Latest Patents

Atsushi Tokida holds a patent for a cigarette filter and filter material therefor. The patent describes a filter material that comprises a cellulose acetate fiber tow containing 5-50% by weight of a water-soluble material and/or a water-dispersible material. These materials are soluble in a solvent that dissolves cellulose acetate and are not compatible with it. The inclusion of these materials allows the fiber surface to become porous in the presence of moisture, increasing the surface area and enhancing the fiber's decomposability by microorganisms. This innovation leads to cigarette filters that are easier to decompose in natural environments, particularly in moist conditions.
