    • 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).
    • 吸液纤维(20)的内部通道(22)填充有选定的液体(18)形式的预聚合的聚合物或相关试剂,然后聚合反应在合适的条件下进行以形成具有所需性质的纤维。 随后可以方便地获得具有形成的聚合物产品性能的纤维。 这提供了通过在芯吸纤维(20)通道(22)中直接聚合单体来获得工程纤维的方便方法。 芯吸纤维(20)包括内部纵向空腔或通道(22),每个具有相对小的纵向延伸开口(24)。 毛细纤维(20)通过毛细作用填充所选择的液体,通过该毛细作用,各个芯吸纤维(20)通过内部空腔(22)快速地吸引与它们接触的选定液体。 所选择的液体保留在芯吸纤维空腔(22)内,并且通常不通过纵向开口(24)进入芯吸纤维之间的空间,液体与芯吸纤维(20)周围的环境完全相通。 形成的固体聚合物保留在芯吸纤维(20)的通道(22)中。

    • A unique odor filtration device (10) which continuously removes odor causing gas phase contaminants from an air stream through the use of partially hollow wicking fibers (20) impregnated with a selected liquid (18) which can capture odor causing gas phase contaminants. The odor removing liquid (18) is a chemical composition including sodium permanganate in combination with either sodium carbonate or sodium phosphate. The odor absorbing liquid (18) can include specialized additives such as transition metal salts and other agents such as sodium iodide for additional and broader odor removal coverage. The wicking fibers (20) are formed into a filter element (12) which extends from a chamber (16) through which the air stream to be cleaned is directed into a stripping chamber (19). The odor causing contaminants are conveyed to from chamber (16) to chamber (19) by a concentration factor induced molecular migration. The wicking fibers (20) include internal longitudinal cavities (22) each with a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected contaminant removing liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected liquid, with which they come into contact, through the internal cavities (22). The absorption liquid (18) 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 air stream flowing past the fibers (20).
    • 一种独特的气味过滤装置(10),其通过使用浸渍有选择的液体(18)的部分中空的芯吸纤维(20)连续地除去来自空气流的气相污染物,所述液体可以捕获产生气味的气相污染物。 气味除去液(18)是包含与碳酸钠或磷酸钠组合的高锰酸钠的化学组成。 气味吸收液体(18)可以包括专门的添加剂,例如过渡金属盐和其它试剂如碘化钠,用于附加和更广泛的除臭覆盖。 芯吸纤维(20)形成为从腔室(16)延伸的过滤器元件(12),待清洁的空气流通过所述腔室引导到汽提室(19)中。 通过浓度因子诱导的分子迁移将产生气味的污染物从室(16)输送到室(19)。 芯吸纤维(20)包括各自具有相对小的纵向延伸开口(24)的内部纵向空腔(22)。 芯吸纤维(20)通过毛细管作用填充所选择的污染物去除液体,通过该作用,各个芯吸纤维(20)通过内部空腔(22)快速地吸引与它们接触的选定液体。 吸收液体(18)保持在芯吸纤维空腔(22)内,并且通常不通过纵向开口(24)进入芯吸纤维之间的空间,液体与流过纤维的空气流(20)完全相通 )。
