Problems solved by technology

The microporous membrane used in this method is easy to cause micropore blockage due to a large amount of tar and particulate matter adhering to the membrane surface during the tar filtration process, and it is difficult to add the membrane to the filter body alone in the actual production process. production difficulties

Abstract

The invention discloses a cigarette filter tip and a production method thereof. A filter tip section comprises four layers of filtering adsorbing materials and reduces tar, solid particles and other harmful gases generated during smoking by a step-by-step adsorption filtration function. The production method of the cigarette filter tip can achieve combination with the existing cigarette production process, does not need to change processing equipment and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of smoke purification, in particular to a cigarette filter and a preparation method thereof, and relates to the preparation of a novel cigarette filter with multiple adsorption structures. The invention can continue to use the original production process of cigarettes to produce low-tar cigarettes. Background technique [0002] The smoke produced when cigarettes burn contains thousands of chemical components, including solid and gaseous substances, most of which are harmful to the human body. The specially produced tar contains a variety of carcinogens such as benzopyrene, nitrosamines, and heavy metals, as well as cancer-promoting substances such as phenols and fumaric acid. According to the American Cancer Society, smokers who smoke less than 10 cigarettes a day are 5 times more likely to develop lung cancer than non-smokers, and those who smoke more than 2 packs a day are 20 times more likely. Up to 1 m...
