摘要： Fibers are produced from an acetone solution of cellulose acetate by pulling or extruding such material through a spinneret in a dry spinning process. A vacuum is applied to the thus formed fibers after a certain degree of drying. A dried outer skin is formed, and the vacuum causes the solvent inside the skin to explode or pop and exit the fiber along micro-porous paths thereby producing high surface area fibers with micro-porous cavities and internal void volume. Such micro-cavities are particularly useful for retaining solid and/or liquid reagents in a cigarette filter for selective filtration of various smoke components.

摘要： The internal channels (22) of wicking fibers (20) are filled with a selected liquid (18) form of a prepolymerized polymer or monomers and related reagents and then the polymerization reaction is carried out under suitable conditions to form a fiber with desired properties. Fibers with the properties of the formed polymeric products are conveniently obtained thereafter. This provides a convenient way to obtain engineered fibers by directly polymerizing the monomers in the wicking fiber (20) channels (22). The wicking fibers (20) include internal longitudinal cavities or channels (22) each with a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected liquid, with which they comes into contact, through the internal cavities (22). The selected liquid remains within the wicking fiber cavities (22) and generally does not enter the space between the wicking fibers yet through the longitudinal openings (24) the liquid is in full communication with the environment surrounding the wicking fiber (20). The formed solid polymer is retained in the channels (22) of the wicking fiber (20).

摘要： A tobacco smoking mixture including an ammonia-release compound adapted to be formed into a lit-end cigarette is provided. The ammonia-release compound is incorporated in or on tobacco cut filler in an amount effective to reduce the cytotoxicity, and/or selective smoke constituents of cigarette smoke. Exemplary ammonia-release compounds include ammonium acetate, ammonium hydroxide, hexammine cobalt (III) chloride, hexammine cobalt (III) acetate, and combinations thereof. The ammonia-release compounds can release ammonia at temperatures between about 60° C. and about 400° C. Ammonia-release compounds can be combined with additives, such as glycerine, cobalt acetate, copper (II) acetate, zinc acetate, other metal salts or combinations thereof, to further reduce the cytotoxicity of cigarette smoke.

摘要： A cigarette filter for removing gas phase constituents from mainstream cigarette smoke as the smoke is drawn through the filter primarily comprises an activated carbon fiber filter section including a bundle of activated carbon fibers. Particulate adsorbent materials such as granules, beads or course powders may be dispersed amongst the activated carbon fibers to aid in removal of the gas phase constituents. Additionally, the activated carbon fiber filter section may be used in combination with a separate bed or beds of particulate adsorbent material. In one embodiment, the activated carbon fibers are positioned within a helical groove on the outside of a threaded rod within the activated carbon fiber filter section. Relatively smaller amounts of activated carbon fibers produce the same smoke constituent reduction as larger amounts of particulate adsorbent material.

摘要： A unique filtration device (10) which continuously removes gas phase contaminants from an air stream through the use of partially hollow wicking fibers (20) impregnated with a fine solid carbon powder (18) or zeolites and formed into a fiber filter (12) with a selected chemisorptive liquid applied to one side of the fiber filter (12) and large carbon particles (19) applied to the other side of the fiber filter (12). The air stream to be cleaned is directed through filter element (12) which can capture the gas phase contaminants. The wicking fibers (20) include internal longitudinal cavities (22) filled with the fine carbon powder (18) and each having a relatively small longitudinal extending opening (24). The wicking fibers (20), to a shallow depth on one side of filter (12), are filled with the selected contaminant removing chemisorptive liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected chemisorptive liquid, with which they come into contact, through the internal cavities (22). The chemisorptive liquid and fine carbon powder (18) or zeolite powder remain within the wicking fiber cavities (22) and generally do not enter the space between the wicking fibers yet through the longitudinal openings (24) the fine carbon particles (18) and the chemisorptive liquid are in full fluid communication with the air stream flowing past the fibers (20).
