    摘要： Fibrous material suitable for incorporation into filter elements of smoking articles such as cigarettes are impregnated with additives and agents such as flavorants, flavorant-enhancers and/or free radical scavengers. The fibrous material is contacted with the additive dispersed in a high pressure gas or supercritical fluid (SCF) held at elevated pressures. The high pressure gas or SCF swells the fibrous matrix and enables the additive to be incorporated within the matrix. When pressure is reduced, the gas or SCF vaporizes and leaves the additive embedded in the fiber interstices. As a result, the additive is slowly released over a finite period of time. When incorporated into a cigarette filter, the additive is released at a desired rate from the interior of the fibrous filter into the cigarette smoke.

    摘要： A process for making modified activated carbon from an activated carbon substrate. The activated carbon substrate is pre-treated to make an exposed surface of the activated carbon substrate substantially hydrophilic, coated with a carbon precursor to form a coated activated carbon, and then the coated activated carbon substrate is heated to carbonize the carbon precursor to from the modified activated carbon. The modified activated carbon comprises a uniform porous carbon membrane formed on an exposed surface of the activated carbon substrate. The carbon membrane can mediate the absorption and/or adsorption kinetics of the activated carbon substrate. The modified activated carbon, which can be incorporated into one or more components of a cigarette, can selectively remove gaseous constituents from mainstream smoke during smoking.

    摘要： A process for the on line production of cigarette filters comprises the steps of conveying a continuous thin flexible substrate past a source of smoke altering particulate material, such as adsorbents, catalysts and flavorants. An electrostatic charge is applied onto the substrate upstream of the source of particulate material. A layer of particulate material from the source is deposited onto the substrate with the thickness of the layer depending upon the strength of the electrostatic charge. The coated substrate is then cut into pieces, and the pieces are placed into the cavities between spaced apart filter components. In an alternative process, filter paper is coated with smoke altering particulate material by electrostatic deposition techniques, and spaced apart filter components are placed onto the particulate coated filter paper which is then folded around the filter components.
