摘要： Disclosed is a filter for tobacco smoke composed of at least one layer of a wet-formed absorbent fibrous nonwoven composite structure containing: 1) from about 30 to about 65 percent by weight, of pulp fibers forming a matrix having a first exterior surface and a second exterior surface, and 2) about 35 to about 70 percent by weight, of activated carbon integrated into the matrix of pulp fibers such that the concentration of activated carbon adjacent the first exterior surface is at least about 60 percent, as determined by optical image analysis, and the concentration of activated carbon adjacent the second exterior surface is less than about 40 percent, as determined by optical image analysis, so that the filter is adapted to selectively reduce the C3-C4 carbonyl component of conventional tobacco smoke at least about 25 percent more than a conventional cellulose acetate filter for an identical tobacco smoke. Also disclosed is a method of making the filter.

摘要： A cigarette is provided with a filter comprising a filter element of water-disintegratable paper. The paper is water swellable and/or the filter element comprises a water swellable agent. Tipping which interattaches the filter to the tobacco rod of the cigarette is anchored by means of water susceptible adhesive. Thus when the cigarette comes into contact with sufficient water, the filter element swells and the tipping opens away from the filter. This facilitates disintegration of the water-disintegratable paper.
摘要翻译：香烟配备有包含水解纸过滤元件的过滤嘴。纸是水可溶胀的和/或过滤元件包含水溶胀剂。将过滤器与香烟的烟草棒相互连接的倾翻通过水敏粘合剂进行锚定。因此，当香烟与充足的水接触时，过滤元件膨胀并且倾斜从过滤器打开。这有助于水解纸的分解。

摘要： A bundle of cellulose acetate fibers is bonded together with a water-soluble fiber-to-fiber bonding agent. The water-soluble fiber-to-fiber bonding agent may include 60-99 wt. % of a water-soluble binder and 40-1 wt. % of a plasticizer. As to the specific components, the water-soluble fiber-to-fiber bonding agent may be a mixture of a water-soluble polymer and glycerol triacetate. The bonded fibers are wrapped in a paper having opposing ends secured together with a water-soluble plug wrap adhesive. A plurality of cuts are made to extend more than one half way through the bundle wrapped fibers. The plurality of cuts may extend more than one half way through the bundle without extending completely through the bundle and may extend from a plurality of different directions. Further, the bundle of wrapped fibers may have cuts extending more than one half way though the bundle from a first direction, and also have a plurality of cuts extending less than one half way through the bundle from a second direction, different than the first direction. If cuts are made from different directions, there is a distance between adjacent cuts made from that direction, and this distance should be in the range of 2 to 7 mm.

摘要： A tobacco smoke filter material comprises a fibrillated cellulose ester fiber with an average fiber diameter of 15 to 250 µm and a BET specific surface area of 0.5 to 4.5 m²/g. The fibrous cellulose ester content of the material may for example be not less than 20 weight %. The cellulose ester fiber is provided by, for example, extruding a cellulose ester solution from a nozzle (2) into a precipitating agent for the particular cellulose ester and subjecting the extrudate to a shear force. This filter material can be used in the form of, for example, a filament, web or sheet to provide a tobacco smoke filter which assures good smoking qualities and excellent wet disintegratability.

摘要： A filter rod is produced by adding a water-soluble polymer in the form of an aqueous solution or dispersion, or in a particulate form, to a tow of cellulose ester fiber, with the amount of any water used being controlled within 25 parts by weight relative to 100 parts by weight of the tow, and wrapping the treated tow in wrapping paper. The water contained in the filter rod is removed or the particulate water-soluble polymer is melted by heating to bond the fiber to provide a tobacco filter. The proportion of the water soluble polymer is 0.5 to 30 parts by weight to 100 parts by weight of the tow. To reduce the amount of water relative to the tow, a hot-melt adhesive water-soluble polymer may be employed. As the amount of water added to the tow is thus decreased, the tow can be smoothly wrapped up even at a high speed so that filter productivity is improved. This tobacco filter is highly wet-disintegratable and, hence, contributes to mitigation of the environmental pollution.
摘要翻译：滤棒通过将水溶液或分散体形式的水溶性聚合物或颗粒形式添加到纤维素酯纤维束中来制备，其中使用的任何水的量被控制在25重量份相对于100重量份的丝束，并且将经处理的丝束包裹在包装纸中。包含在过滤棒中的水被除去或者颗粒状水溶性聚合物通过加热熔化以粘合纤维以提供烟草过滤器。相对于100重量份的丝束，水溶性聚合物的比例为0.5〜30重量份。为了减少相对于丝束的水量，可以使用热熔粘合剂水溶性聚合物。当添加到丝束中的水量因此减少时，丝束即使在高速下也能平稳地卷绕，从而提高了过滤器的生产率。这种烟草过滤嘴是高度湿分解的，因此有助于减轻环境污染。
