The present disclosure relates to a lyocell material with controlled whiteness by hydrogen peroxide treatment and a manufacturing method thereof, wherein the lyocell material has improved whiteness due to an aging effect through drying and packaging by a predetermined amount of hydrogen peroxide remaining in a tow, and may replace a CA cigarette filter to lower environmental pollution problems caused by discarded cigarette butts, and thus the lyocell material is suitable as a cigarette filter.

The present disclosure relates to a filter for cigarettes and a method of preparing the filter, and provides a paper filter for cigarettes using paper and a cigarette including the paper filter. The filter for cigarettes provides a high level of satisfaction in smoking through high granular seating stability and eliminates a burnt taste. Various embodiments described herein in relation to the filter for cigarettes and the method of preparing the filter may be applicable.

Shown is a filter material for manufacturing a segment for a smoking article, wherein the filter material is hydroentangled and contains at least 50% and at most 100% cellulose fibers, each with respect to the mass of the filter material, wherein the filter material has a basis weight of at least 15 g/m.sup.2 and at most 60 g/m.sup.2, wherein the thickness of one layer of the filter material, measured in accordance with ISO 534:2011, is at least 25 ?m and at most 400 ?m, and wherein the filter material has a creep tendency in the thickness direction of at most 10%, wherein the creep tendency is the relative decrease in the thickness of 5 layers of the filter material, measured in accordance with ISO 534:2011, within 20 s after the start of the thickness measurement.

The invention relates to a filter manufacturing apparatus (1) to form a hollow filter body, the filter manufacturing apparatus comprising: a feed path adapted to continuously feed a filter material along a longitudinal transport direction (30); a forming device (4) connected to a terminating end of the feed path and adapted to form the filter material into a hollow rod-shaped filter body and deliver the formed filter body, the forming device including: .square-solid. a tubular forming element (8) adapted to allow the filter material to pass therethrough, .square-solid. a pin (34) extending longitudinally within the tubular forming element, the pin having a pin diameter;a diameter changing device (40), adapted to vary the pin diameter of the pin, so as to obtain a filter body having a through hole of variable diameter.

The present invention relates to a filter manufacturing apparatus comprising: a feed path adapted to continuously feed a filter material along a longitudinal transport direction; a forming device connected to a terminating end of the feed path and adapted to form the filter material into a continuous filter body and to deliver the formed continuous filter body, the forming device including: a tubular element (8) adapted to allow the filter material to pass therethrough to form the filter tow material into the continuous filter body; and a steam generator (9) adapted to produce steam, the steam generator being in fluid communication with the tubular element to supply steam to the filter material; a drain channel (10) in fluid communication with the tubular element adapted to drain fluid from the tubular element; a valve adapted to open and close the drain channel so as to allow or block discharge of fluid from the tubular element.

A component for an article for use in an aerosol provision system includes a body of material, wherein the body has a longitudinal axis and includes one or more sheets extending through the body, said one or more sheets having an aerosol modifying additive and having a total width of between about 100 mm and about 350 mm. An article and a method of manufacture are also provided.

The present invention relates to a cigarette filter and a method for manufacturing same, and can provide a paper cigarette filter using paper and a cigarette comprising same. A cigarette filter according to one embodiment of the present invention can impart a high degree of smoking satisfaction through high granule stability, and eliminate a burnt taste. Hereinafter, various embodiments related to a cigarette filter and a method for manufacturing same may be possible.

A manufacturing device for a filler element includes a sheet processing section forms a crimped part on a sheet and a feed portion that continuously feeds an additive dropwise onto an upper face of the sheet having the crimped part. The feed portion includes a multiple nozzle in which a large number of feed outlets feeding the additive are arranged in the width direction.

This filler element is used in a flavor inhaler, and comprises: a folded part in which one sheet composed of a nonwoven fabric has been folded in the width direction Z intersecting the longitudinal direction X thereof, and the diameter thereof has been reduced to a size not greater than the diameter of the filler element; and wrapping paper that is wrapped on the folded part. A section of the folded part in the circumferential direction thereof has an opening that is open along the axial direction X of the folded part, and an additive is placed on the interior of the folded part via the opening.

The present invention relates to improvements in filters, for use in smoking articles, comprising randomly oriented discrete fibres, wherein a loss of particulate additives can be reduced by adding a liquid with a viscosity of at least 2000 m Pa*s at 20 C. and normal pressure.
