FILTER INCLUDING RANDOMLY-ORIENTED FIBERS FOR REDUCTION OF PARTICLE BREAKTHROUGH

Disclosed is a cigarette filter (10) and method of making the filter. The filter includes an adsorbent (12) dispersed within the filter and a downstream plug (16) of randomly-oriented fibers (14). The randomly-oriented fibers mechanically capture adsorbent particles entrained in tobacco smoke. One o...

Zusammenfassung:	Disclosed is a cigarette filter (10) and method of making the filter. The filter includes an adsorbent (12) dispersed within the filter and a downstream plug (16) of randomly-oriented fibers (14). The randomly-oriented fibers mechanically capture adsorbent particles entrained in tobacco smoke. One or more plugs (25) of axially-oriented fibers (30) may also be located upstream or downstream or both of the adsorbent, and are included in an amount sufficient to adjust the length of the filter.
