Technical Field

Background
After the traditional cigarette is ignited, the tobacco shreds continuously release smoke due to incomplete combustion; the tobacco products which are not burnt are heated, and the smoke is released by roasting the smoke bomb at high temperature, which is the main mode for generating CO in the smoke, and the CO is sucked excessively and is harmful to human bodies.
Common CO adsorption modes in the cigarette industry mainly include physical interception of a filter tip and adsorption of functional particles. The physical interception is that when smoke passes through the filter tip, CO flows in the filter tip and continuously collides with filter tow in the moving process of the CO, so that the CO is intercepted; function particle adsorbs, and used granule is mostly porous granule, and it has the characteristics that inside pore is many, specific surface area is big, adsorption efficiency is strong, when CO flows in inside pore, because the movement path overlength, kinetic energy is consumed totally, is detained inside the function granule to adsorbed, not inhaled the oral cavity.
Both of the above methods have drawbacks: the physical interception method has low interception efficiency, and because CO is small molecules and gaps formed among tow fibers in the filter tip are large, the CO can pass through the gaps and cannot be intercepted; the functional particles have no selectivity in adsorption, and adsorb most of smoke substances while adsorbing CO, so that the smoke quality is reduced, and the smoking taste is influenced.
