Abstract: A method of manufacturing a wrapper for an aerosol generating article includes applying an adhesive to one surface of a metal layer and attaching a first paper layer thereto, applying the adhesive to the other surface of the metal layer and attaching thereto a second paper layer different from the first paper layer, and drying the adhesive applied between the metal layer and the first paper layer and the adhesive applied between the metal layer and the second paper layer.

Abstract: An embodiment of the present invention provides a tipping paper for smoking articles. The tipping paper includes a fragrance carrier including a fragrance material and a carrier material, the carrier material includes the fragrance material, and the fragrance material included in the carrier material is disseminated from the tipping paper in response to moisture, saliva, or friction, and the carrier material is a material soluble in ethanol.

Abstract: A lyocell material for a cigarette filter and a method of manufacturing the same are disclose. The lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to obtain a crimped tow.

Abstract: The present disclosure provides an externally heated aerosol generation device and a cigarette that may provide a sufficient amount of atomization to allow a user to have a satisfactory smoking experience even during an initial puff because thermal energy is easily transferred to the cigarette.

Abstract: A cigarette filter comprises a first filter portion comprising an irregularly folded and packed polymer sheet, and a first cigarette filter wrapping paper surrounding the polymer sheet, wherein the polymer sheet comprises a first polymer layer containing polyolefin or polyester and a second polymer layer positioned on the first polymer layer and containing polyolefin.

Abstract: 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.

Abstract: A cigarette for an aerosol generating device includes a tobacco rod including an aerosol generating substrate wrapped with a wrapper and a filter through which an aerosol generated from the aerosol generating substrate passes. The filter comprises cellulose acetate tow having a total denier of a preset value.

Abstract: An aerosol-generating article according to an embodiment may include a medium portion, a front end plug disposed to face an upstream end of the medium portion, and a filter portion disposed to face a downstream end of the medium portion, wherein the front end plug includes a channel extending from the upstream end to the downstream end.

Abstract: A lyocell material for a cigarette filter and a method of manufacturing the same are disclose. The lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to obtain a crimped tow.

Abstract: This invention relates to a lyocell material for a cigarette filter and a method of manufacturing the same, wherein the lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to thus obtain a crimped tow.

Abstract: 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.

Abstract: An optical fiber preform manufacturing method whereby a clad layer and core layer are deposited on the inner surface of a preform tube for forming a deposited tube. One end of the deposited tube is shrunk and closed. The deposited tube which has a closed end is arranged extending vertically through a circular heater. A heat is applied to the deposited tube at a temperature lower than the softening point of a deposited tube, exhausting contaminants existing in the interior of the deposited tube while moving the circular heater. The heating temperature of the circular heater is then set to a temperature not lower than the softening point of the deposited tube-to shrink and close the deposited tube.

Abstract: Disclosed is an optical fiber coating device for coating the outer circumference of the optical fiber with the coating material, in which the coating device is provided with and a gas provider for providing an environmental gas within the coating device, and a cooler for cooling down the environmental gas provided to the coater from the gas provider.
