ABSTRACT:
A cigarette has a blend of tobacco materials and a filter element provided from a non-woven thermoplastic material. The non-woven material comprises polyester or polypropylene fibers. The non-woven material is in intimate contact with a high molecular weight material (e.g., an emulsifier or another polymeric material). As such the filter material is coated with another polymeric material. The coated non-woven material can be in intimate contact with an acidic material (e.g., lactic acid) or a basic material (e.g., sodium hydroxide). Certain cigarettes can have relatively high nicotine smokable blends and filter elements having the coated non-woven filter material in intimate contact with an acidic material. Certain other cigarettes can have relatively low nicotine smokable blends and filter elements having the coated non-woven filter material in intimate contact with a basic material. Certain other cigarettes can be "ultra low tar" cigarettes including filter elements having the coated non-woven filter material in intimate contact with a basic material.
