Abstract
Изобретение относится к сигарете с фильтром с биологически разлагаемым фильтром с окруженным сигаретной бумагой табачным жгутом, с фильтром, изготовленным из полученного способом воздушной струи целлюлозного нетканого полотна, с нормальной удерживающей способностью и с проходящей в окружном направлении вентиляционной зоной фильтра. Она включает комбинацию следующих признаков: фильтр имеет удерживающую способность для конденсата 40-60%; целлюлозное нетканое полотно «неусаженное»; соотношение выходов жгута никотин/конденсат табачного жгута лежит в диапазоне 0,6-0,9 (никотин*10/конденсат); плотность набивки табачной смеси в табачном жгуте лежит в диапазоне 200-250 мг/мл; сопротивление затягиванию табачного жгута лежит в диапазоне 45-65 mmWS, замерено закрытым; воздухопроницаемость сигаретной бумаги составляет 20-50 Coresta-единиц; и степень вентиляции фильтра составляет 15-50%.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to a filter cigarette with a biodegradable filter with tobacco bundle surrounded by cigarette paper, with a filter made of cellulose nonwoven fabric obtained by the method of an air jet, with a normal retention capacity and with a ventilation zone in the circumferential direction. It includes a combination of the following features: the filter has a retention capacity for condensate 40-60%; cellulose nonwoven non-woven fabric; the ratio of nicotine / tobacco condensate tow loops is in the range of 0.6-0.9 (nicotine * 10 / condensate); the packing density of the tobacco mixture in the tobacco bundle lies in the range of 200-250 mg / ml; resistance to tightening the tobacco bundle is in the range of 45-65 mmWS, measured closed; air permeability of cigarette paper is 20-50 core units; and the degree of ventilation of the filter is 15-50%. The international application was published along with an international search report.
