Abstract

Настоящее изобретение относится к сигаретному фильтру (10) и способу изготовления фильтра. Фильтр (10) содержит адсорбент (12), распределенный внутри фильтра (10), и расположенную за ним по потоку заглушку (16) из беспорядочно ориентированных волокон (14). Беспорядочно ориентированные волокна (14) механически захватывают частицы адсорбента, увлекаемые табачным дымом. Одна или более заглушек (25) из аксиально ориентированных волокон (30) могут быть также расположены по потоку за или перед или как перед, так и за адсорбентом (12) в количестве, достаточном, чтобы отрегулировать длину фильтра (10).The present invention relates to a cigarette filter (10) and a method for manufacturing a filter. The filter (10) contains an adsorbent (12) distributed inside the filter (10), and a plug (16) located behind it downstream of randomly oriented fibers (14). Randomly oriented fibers (14) mechanically capture adsorbent particles entrained in tobacco smoke. One or more plugs (25) of axially oriented fibers (30) can also be located downstream of or in front of or both in front of and behind the adsorbent (12) in an amount sufficient to adjust the length of the filter (10).
