Abstract

A CIGARETTE FILTER INCLUDES A MULTIPLE SECTION FILTER WHICH REDUCES THE LEVEL OF PREDETERMINED SMOKE CONSTITUENTS. THE FILTER (130) CONSISTS OF A FIBROUS FILTER PLUG (132) LOCATED AT THE MOUTH-END OF THE CIGARETTE, A SECTION (136) CONTAINING A SELECTIVE ADSORBENT MATERIAL (146), AND A SECTION (134) CONTAINING A GENERAL ADSORBENT MATERIAL (144). THE SELECTIVE ADSORBENT MATERIAL (146), SUCH AS A PHENOL-FORMALDEHYDE RESIN MATRIX SURFACE-FUNCTIONALIZED WITH MAINLY PRIMARY AND SECONDARY AMINE FUNCTIONAL GROUPS, REMOVES SPECIFIC SMOKE CONSTITUENTS FROM THE TOBACCO SMOKE. THE GENERAL ADSORBENT MATERIAL (144) SUCH AS ACTIVATED CHARCOAL, IS PREFERABLY CAPABLE OF ADSORBING A RANGE OF CHEMICAL COMPOUNDS WITHOUT A HIGH DEGREE OF SPECIFICITY. STRUCTURALLY, THE FIBROUS FILTER PLUG (132), THE SELECTIVE ADSORBENT SECTION (136), AND THE GENERAL ADSORBENT SECTION (134) ARE AXIALLY ALIGNED IN TANDEM. (FIG. 2)
