A smoking product includes: a smoking material portion which is wrapped by a smoking material wrapper; a filter portion whose upstream end portion is combined with the smoking material portion, which includes a capsule containing a flavoring, and which is wrapped by a filter wrapper; and a tipping wrapper which surrounds at least a partial region of the smoking material portion and the filter portion so that the smoking material portion and the filter portion are combined, wherein the tipping wrapper includes a first perforation region including a plurality of perforations formed along an outer circumferential surface of the tipping wrapper and a second perforation region including a plurality of perforations formed downstream of the first perforation region and along the outer circumferential surface of the tipping wrapper, and the capsule is disposed downstream of the first perforation region and upstream of the second perforation region.

Smoking articles including filter elements formed from two or more fibrous inputs with different physical properties are provided. The two or more fibrous inputs are provided in the form of staple fibers, which are at least partially entangled with each other to form a mixed fiber sliver. The mixed fiber sliver includes a first plurality of cellulose acetate staple fibers blended with a second plurality of staple fibers comprising a polymeric material different from the first plurality of staple fibers, such as staple fibers of a degradable polymeric material. The entangled fibers of the mixed fiber sliver may be sufficiently separated from one another such that blooming operations typically required in filter element production may not be necessary prior to incorporating the mixed fiber sliver into a filter element. Related methods, apparatuses and mixed fiber products are also provided by the disclosure.

The filter using technology for reducing the smell of tobacco smoke on hands, according to one embodiment of the present invention, comprises: a filter unit for filtering tobacco smoke, the filter unit being coupled to a tobacco shred; and filter-wrapping paper for wrapping the filter unit. The filter unit or the filter-wrapping paper may contain a material for reducing the smell of tobacco smoke. According to the embodiment of the present invention, green tea extracts containing catechin or other materials for reducing the smell of tobacco smoke, e.g. citric acids, glycerols, tannic acids and the like can be added to a tobacco filter to remove the smell from tobacco smoke generated during smoking, thus significantly lowering the strength of the smell of tobacco smoke on the hands of a smoker as compared to conventional tobacco filters.
