    摘要： A process of retaining fine adsorbent particles such as carbon material or APS silica gel in the micro-cavities of a shaped fiber comprises the steps of continuously conveying a shaped fiber with micro-cavities to a charging arrangement where the fiber is electrostatically charged. The electrostatically charged fiber is then drawn through a reservoir of the fine adsorbent particles. As the fiber passes through the reservoir the fine particles adhere to the fiber and the micro-cavities thereof. Any excess particles are removed from the fiber outside the reservoir. Subsequently the shaped fiber loaded with fine adsorbent particles is collected for use in filter applications of one type or another such as cigarette filters, for example.

    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： 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).
