Abstract

A találmány tárgya egy szűrős cigaretta biológiailag lebonthatószűrővel, amely egy cigarettapapírral körülvett dohánytöltettel, egynormál" visszatartó teljesítménynyel rendelkező, az Air-Laid"-eljárással készített cellulóz fátyolbundából előállított szűrővel ésegy kerületi irányban elhelyezkedő szűrő-szellőzési zónávalrendelkezik. Továbbá az alábbi jellemzőket foglalja magába: a szűrőkondenzátum-visszatartó teljesítménye 40-60%; a cellulóz-fátyolbundazsugorítatlan; a dohánytöltet nikotin/kondenzátum töltetkihozatal-viszonyszáma 0,6 és 0,9 közötti értéket képez (Nikotin*10/kondenzátum); a dohánytöltet dohánykeverékének tömítési sűrűsége200 és 250 mg/ml közötti értéket képez; a dohánytöltet huzat-ellenállása 45 és 65 mmWS közötti értéket képez, zárt állapotbanmérve; a cigarettapapír levegőáteresztőképessége 20-50 Coresta-egység;és a szűrési-szellőzési mértéke 15-50%. ÓThe subject of the invention is a filter cigarette with a biodegradable filter, which consists of a tobacco filling surrounded by cigarette paper, a filter produced from cellulose veil fleece with a normal "retentive performance" produced by the Air-Laid process, and a filter ventilation zone located in the circumferential direction. Furthermore, it includes the following characteristics: the performance of the filter condensate retention is 40-60%; the cellulose veil fleece is unshrunk; the nicotine/condensate charge yield ratio of the tobacco charge is between 0.6 and 0.9 (Nicotine*10/condensate); the sealing density of the tobacco mixture of the tobacco filling is between 200 and 250 mg/ml; the draft resistance of the tobacco filling is between 45 and 65 mmWS, measured in the closed state; the air permeability of the cigarette paper is 20-50 Coresta units; and the degree of filtration and ventilation is 15-50%.
