Abstract
Filter rods for cigarette manufacture include a plurality of strands of a reconstituted tobacco material. The tobacco material includes a sizing agent having a hydrophobic character. A rod having a circumference of about 24 mm can have about 320 strands of a sheet-like material cut at about 32 cuts per inch. The strands extend along the longitude of the rod. The filter elements provided from the rods provide a useful mouthpiece for cigarettes and also impart a unique tobacco taste.
Claims34
A rod for the preparation of cigarette filter elements, the rod comprising a plurality of strands provided from tobacco-containing, nonwoven sheet-like material, wherein (i) the strands extend generally along the longitude of the rod, each have a width greater than the thickness thereof, and are contained in a circumscribing wrap;
- and (ii) the sheet-like material includes a sizing agent having a hydrophobic character.
A rod for the preparation of cigarette filter elements, the rod comprising a plurality of strands provided from tobacco-containing, nonwoven sheet-like material, wherein (i) the strands extend generally along the longitude of the rod, each have a width greater than the thickness thereof, and are contained in a circumscribing wrap;
- and (ii) the sheet-like material includes a sizing agent having a hydrophobic character, the sizing agent being an alkylketene dimer.
An essentially cylindrical filter element for a smoking article, the filter element comprising a plurality of strands provided from tobacco-containing, nonwoven sheet-like material, wherein (i) the strands extend generally along the longitude of the element, each have a width greater than the thickness thereof, and are contained in a circumscribing wrap;
- and (ii) the sheet-like material includes a sizing agent having a hydrophobic character.
The filter element for a smoking article, the filter element comprising a plurality of strands provided from tobacco-containing, nonwoven sheet-like material, wherein (i) the strands extend generally along the longitude of the element, each have a width greater than the thickness thereof, and are contained in a circumscribing wrap;
- and (ii) the sheet-like material includes a sizing agent having a hydrophobic character, the sizing agent being an alkylketene dimer.
A cigarette comprising a rod of smokable material aligned with and having attached to one end thereof a filter element, the filter element having a plurality of strands provided from tobacco-containing, nonwoven sheet-like material, wherein (i) the strands extend generally along the longitude of the rod, each have a width greater than the thickness thereof, and are contained in a circumscribing wrap;
- and (ii) the sheet-like material includes a sizing agent having a hydrophobic character.
A cigarette comprising a rod of smokable material aligned with and having attached at one end thereof, two filter elements in sequence, one of which filter elements has a plurality of strands provided from tobacco-containing, nonwoven sheet-like material, wherein (i) the strands extend generally along the longitude of the rod, each have a width greater than the thickness thereof, and are contained in a circumscribing wrap;
- and (ii) the sheet-like material includes a sizing agent having a hydrophobic character.
