Abstract

The invention discloses a cigarette filter rod provided with a natural mineral and plant fiber composite additive, and belongs to the technical field of cigarettes. The cigarette filter rod is prepared according to the following steps that (1), a raw additive material is composited and subjected to compatibility; (2), the composite additive is subjected to surface treatment; (3), a blended spinning bundle of the composite additive and an acetate fiber is prepared; the composite additive and an acetate fiber solution are blended at a ratio of 1:(50-90) and then ejected from a nozzle of a spinning machine to form the blended spinning bundle; and (4), the blended spinning bundle and a routine filament bundle are placed together at a set ratio and in a set structure, and wrapped with forming paper to form the cigarette filter rod. According to the cigarette filter rod, the novel composite additive is added, so that the content of HCN (hydrogen cyanide) in smoke is reduced, the cigarette safety is improved, and the cigarette smoking quality is ensured; and the novel cigarette filter rod has extensive popularization significance.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a cigarette mouthpiece with composite additives capable of significantly reducing the content of hydrocyanic acid in cigarette smoke and having a certain effect of increasing flavor and soothing sleep. Background technique [0002] In the prior art, hydrocyanic acid (HCN) is one of the harmful components of cigarette smoke on the Hoffmann list and one of the seven representative harmful components established by the cigarette hazard index system. It exists in the form of gas at room temperature and is highly volatile. It is a highly toxic substance that can be inhaled through various routes to poison people. At present, the method of reducing HCN in cigarette smoke is mainly to use a two-stage or three-stage composite filter tip, and add materials with a certain adsorption effect to the filter tip, mainly including activated carbon, molecular sieve, silica gel, por...
