Example Embodiment

[0035] Example 1

[0036] This embodiment provides a cigarette filter tip and a preparation method thereof. The preparation steps are as follows:

[0037] (1) Set the thickness to 5mm and the weight to 150g / m 2 Porous PET scaffold with thickness of 0.3mm, resistance of 3Pa, 12g / m 2 The electret PP meltblown non-woven fabric, the thickness of 30μm microporous PET film, the thickness of 0.5mm, 50g / m 2 The PET skeleton non-woven fabric is laminated and compounded sequentially by hot pressing to obtain a filter section.

[0038] (2) Combine the prepared filter section with two cellulose acetate sections, which are respectively located on both sides of the filter section, to obtain a cigarette filter with a three-section structure.

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...
