Abstract

The present invention discloses a filter tip for cigarette, including fibre base material, and it is characterized by that an electrolyte material is added in the fibre base material, the described fibre base material is acetyl fibre, polypropylene fibre or paper fibre, and the described electrolyte material is one of sodium carbonate, potassium carbonate, sodium nictrate, potassium citrate, aluminium polychloride, aluminium iron polysulfate compound salt, polyacrylamide, sodium polyacrylate, sodium copper chlorophyllin and sodium iron chlorophyllin or several combinations. Said invention not only can reduce tar and harmful chemical component in the main smoke gas of virginian-type cigarette, but also does not affect quality of the cigarette.

Description

Technical field: [0001] The invention relates to a filter for cigarettes. technical background: [0002] Reducing the tar and harmful components of mainstream smoke is a common task faced by tobacco workers all over the world. At present, the commonly used methods include filter ventilation and composite filter technology, and the most commonly used additive material in composite filters is activated carbon. In Japan, more than 70% of the cigarettes sold in the market in 1992 used activated carbon composite filters, and the "biological filter" invented by BF Company in Greece used hemoglobin and activated carbon materials. According to reports, activated carbon filters can reduce certain harmful components in smoke and reduce the harm of smoking to human health, while BF filters have a more significant effect of eliminating harmful components in smoke. Research on new composite filter additive materials has never stopped until now. However, in China, the popularization and...
