    摘要： Cigarette filters, methods for making cigarettes and methods for smoking cigarettes are provided, which involve the use of an unfunctionalized porous polyaromatic resins, which is capable of removing at least some of at least one gas phase constituent from mainstream smoke through sorption. The unfunctionalized porous polyaromatic resin may be a polymerization product of non-polar styrene and divinyl benzene. Various gas phase constituent can be removed from mainstream tobacco smoke, such as dienes, furans, pyrroles, aromatics and ketones, for example. The cigarette filters and cigarettes can provide low resistance-to-draw and/or high total particulate matter delivery. Additionally, the unfunctionalized porous polyaromatic resin may further include flavorant(s).

    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： A process of impregnating fine adsorbent particles such as carbon dust or APS silica gel powder into the micro-cavities of shaped fibers comprises the steps of continuously conveying shaped fibers with micro-cavities to a reservoir of the fine adsorbent particles. The fibers pass through the reservoir to thereby produce relative motion between the fibers and the particles. Additionally, impact forces are created between the shaped fibers and the fine particles to assist in impregnating the particles into the micro-cavities of the fibers. Any excess particles are removed from the fibers outside the reservoir, and subsequently the shaped fibers impregnated with fine adsorbent particles are collected for later use in filter applications such as cigarette filter and air filter applications, for example.

    摘要： A cigarette filter having a reagent which chemically reacts with and removes a gaseous component of a smoke stream. The reagent contains functional groups covalently bonded to a non-volatile inorganic substrate which is incorporated in the filter. The filter can remove gaseous components such as aldehydes from tobacco smoke. Preferred functional groups are 3-aminopropylsilyl groups covalently bonded to silica gel (APS silica gel). The reagent can be contained in a space in the filter or incorporated in one or more filter elements such as tipping paper, shaped paper insert, mouthpiece plug, solid filter element, or free-flow filter element. The reagent can be part of or coated on paper such as tipping or filter paper or incorporated in non-paper filter elements formed from fibrous materials such as cellulose acetate or polypropylene fibers. Other preferred reagents include aminoethylaminopropylsilyl (AEAPS) silica gel and aminoethylaminoethylaminopropylsilyl (AEAEAPS) silica gel.
