摘要： There is provided a particle-filter comprising at least one hydrogel formed in aqueous solution at a temperature below 0° C. The filter can arrest particulates of smoke by physisorption on the solid surface of the gel or by chemisorption if the gel is suitably functionalized. The effectiveness of filter in arresting the solid particles and the pressure drop can be controlled by varying the porosity and the pore size distribution of the filter which in turn can be modulated by varying the monomer to water and monomer to cross-linker ratio in the pre-polymer solution. The filter is able to reduce the particle content of the smoke. There is further provided a cigarette comprising at least one particle-filter according as well as a method for the filtration of smoke.

摘要： A filter material of a filter element configured for application in a smoking article may include a fibrous substrate material finished with a fiber finish composition. The fiber finish composition may be formulated to selectively interact with at least one target component of mainstream smoke drawn through the filter element during use of the smoking article to selectively filter the target component from the smoke. The filter element may include multiple filter segments. Each filter segment may include a filter material having a finish composition formulated to selectively interact with a different target component. The various filter segments may be combined and/or arranged to selectively filter the mainstream smoke to achieve desired characteristics. Each filter segment may be formed from the same fibrous substrate material.

摘要： A degradable cigarette filter includes a filter element of a bloomed cellulose acetate tow, a plug wrap surrounding the filter element, and either a coating or a pill in contact with the tow. The coating and/or pill may be composed of a material adapted to catalyze hydrolysis of the cellulose acetate tow and a water-soluble matrix material. The material may be an acid, an acid salt, a base, and/or a bacterium adapted to generate an acid. The coating may be applied to the tow, the plug wrap, or both. The pill may be placed in the filter element. When water contacts the water-soluble matrix material, the material adapted to catalyze hydrolysis is released and catalyzes the hydrolysis, and subsequent degradation, of the cellulose acetate tow. The foregoing is also applicable to articles made of cellulose esters.
