A kind of multi-segment composite cigarette filter rod and its preparation method and application of expanded plant particles

Abstract

The invention discloses a multi-section composite cigarette filtering stick, a preparation method of the multi-section composite cigarette filtering stick and application of turgid plant granules. A filtering element of the filtering stick is at least composed of two unit sections. One unit section is a fiber substrate, and the other unit section is a fiber substrate comprising the turgid plant granules The preparation method includes the steps that the fiber substrate comprising the turgid plant granules is prepared firstly, the unit section of the fiber substrate comprising the turgid plant granules is prepared secondly, and the unit section of the fiber substrate comprising the turgid plant granules is combined with the fiber substrate unit section to form a binary composite filtering stick or a multi-component composite filtering stick finally. The turgid plant granules are applied to the cigarette filtering stick, tars and other harmful composition existing in the smoke can be reduced greatly, and a special aroma can be endowed on the smoke in the smoking process.

Description

technical field [0001] The invention relates to a multi-section composite cigarette filter rod, a preparation method thereof and the application of expanded plant particles, belonging to the field of cigarettes. Background technique [0002] In recent years, domestic and foreign tobacco companies have conducted a lot of research on the composite filter of various adsorption materials. The research shows that the cigarette filter is an important and effective means of reducing tar and harm. With the continuous deepening of the research on the forming characteristics and filtering mechanism of various filter materials, the development and application of composite filters are gradually becoming the focus of research at present and in the future. With the rapid development of "low-tar, low-hazard" cigarettes, research on the application of filter materials for cigarette composite filters has attracted widespread attention. Cigarettes have very few filter materials. [0003] At...

Chinese patents with application numbers 201010584588.1 and 2011102339661.6 respectively disclose a natural plant filter material for filter tips and its preparation method. The natural plant stem pith material is used as the filter material, which has a good adsorption effect on cigarette smoke and has a unique Pharmacological value, but its method also has obvious deficiencies, the added stem pith particles are too fine and too light, which is not conducive to the production of filter rods
