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.
