A cigarette filter which includes lyocell tow made of a plurality of lyocell fibers, a binder configured to bond the lyocell fibers to each other, and a solvent dispersed in an inner space of the cigarette filter including the lyocell tow, wherein the solvent includes a polyhydric alcohol, is provided. According to one embodiment of the present disclosure, the polyhydric alcohol is a diol having a C1-C4 alkylene group. The cigarette filter according to one embodiment of the present disclosure overcomes the existing material-related problems of lyocell tow and has excellent hardness.

The present invention relates to a filter comprising a nonwoven substrate having a low density and comprising natural fibers and a binder. The filter can be used as a filter for a smoking or vaping article.

A cigarette filter which includes lyocell tow made of a plurality of lyocell fibers and a binder configured to bond the lyocell fibers to each other is provided. The cigarette filter according to one embodiment of the present disclosure reduces each of tar and nicotine, which are delivered through cigarette smoke, by 70% to 95%. The cigarette filter according to one embodiment of the present disclosure has a resistance to draw of 80 mmWG to 200 mmWG. The cigarette filter according to one embodiment of the present disclosure is filled with the lyocell tow at a packing density of 0.2 g/mL to 0.6 g/mL. The cigarette filter according to one embodiment of the present disclosure addresses basic material-related problems, such as low hardness, of the lyocell tow and, further, has excellent filtration functionality as a filter.

The present invention provides a method of forming a filter rod (R) of separated fibres and/or randomly oriented filter material fibres (F) for the tobacco processing industry, the method comprising: supplying separated filter material fibres (F) to an inlet (I) of a conveyor device (2), conveying the separated filter material fibres (F) along a process path (P) in a conveying direction (D) from the inlet (I) to an outlet (O) of the conveyor device (2), whereby a strand (4) of the filter material fibres (F) is formed along the process path (P), introducing at least one additive (A), especially a binder, to the strand (4) of filter material fibres (F) on the process path (P) in the conveyor device (2) at a position that is closer to the outlet (O) than the inlet (I), and consolidating the filter material fibres (F) into a filter rod (R) by wrapping the strand (4) of filter material fibres (F) with a wrapper material (6) after the strand (4) exits the outlet (O) of the conveyor device (2) in the conveying direction (D). Desirably, the at least one additive (A) is introduced or applied to the strand (4) of filter material fibres (F) proximate or adjacent to the outlet (O) of the conveyor device (2). The invention also provides an apparatus (1) for forming such a filter rod (R) of separated and/or randomly oriented filter material fibres (F).

Provided is a material (cigarette component) that enables the elimination or minimization of illicit cigarette production. Specifically, related is a cigarette filter tow band including a crimped bundle of filaments. The tow band includes a detectable marker for identifying the source of the tow band.

The present disclosure provides a cigarette filter including lyocell tow including a bundle of lyocell fibers, a moisturizer, and a binder, a smoking article including the cigarette filter, and a method of producing the cigarette filter.

The present disclosure provides a smoking article filter including lyocell tow including a plurality of lyocell fibers, a phenolic functional material, and a binder and a method of producing the smoking article filter and provides a smoking article including the smoking article filter.

The present invention relates to a filter comprising a nonwoven substrate having a low density and comprising natural fibers and a binder. The filter can be used as a filter for a smoking or vaping article.

A smoking tip filter with a central channel infused with consumable flavorants, surrounded by non-infused paper layers. A barrier prevents diffusion beyond the channel. Inserting into a smoking device flavors smoke via central channel contact only, without burning additives. Enables enjoyable tailored flavors; avoids harsh tastes or paper contamination.

The forming apparatus comprises a feed path for continuously feeding a continuous tow material along a transport direction, a forming device connected to a downstream end of the feed path and adapted to form the continuous tow material into a continuous tubular rod. The forming device comprises a tubular element adapted to allow the continuous tow material to pass through the tubular element to form the continuous tubular rod and a steam generator adapted to generate overheated steam. The steam generator is in fluid connection with the tubular element to provide overheated steam to the continuous tow material. The forming device further comprises several fluid conduits to provide overheated steam from the steam generator to several injection sites arranged along a length of the tubular element, wherein at least one fluid conduit of the several fluid conduits comprises a temperature control unit including a temperature sensor and a temperature influencer.
