Abstract

Изобретение касается высокоэффективного фильтра, содержащего волокна (22), которые содержат адсорбенты/абсорбенты (23) с малым размером частиц, такие как уголь или диоксид кремния, для селективного снижения содержания целевых компонентов в основном потоке сигаретного дыма. Изобретение относится к новому классу высокоэффективных фильтров, предназначенных для фильтрации сигаретного дыма и содержащих гораздо более мелкие частицы (предпочтительно с диаметром 1-50 мкм), загруженные в профильные волокна (22), имеющие открытую или полуоткрытую микрополость. Изобретение также относится к сигарете (10) с конфигурацией жгут/пространство/жгут (12, 14, 16) или жгут/пространство (12, 14), причем в указанное пространство включен загруженный фильтр прикрепленным или неприкрепленным образом для возможности регулирования доставки ТРМ (твердых частиц).Международная заявка была опубликована вместе с отчетом о международном поиске.
