Description
Technical field
The utility model belongs to acetate fiber technical field, is related to one kind and contains porous cellulose diacetate particle aggregate
Three-element composite filter core.
Background technique
The filter element of main flume after cigarette filter rod burns as cigarette, to promotion smoking property of cigarette quality and safety
It plays a very important role.As smoking is goed deep into health research, the safety for improving smoking is increasingly becoming tobacco business
The common objective that can be survived and develop.The tobacco product production firm of countries in the world to Novel tobacco filtering material and
The research and development of filter stick are increasingly paid attention to.
Currently, cigarette filter rod is most or is single cellulose acetate filter rod, it is not more than 1.2kPa condition in resistance to suction
Under, cellulose acetate filter rod is up to 50% left side to total granules (total particulate matter, TPM) filter efficiency
It is right.If the cellulose acetate filter rod for keeping tradition single reaches 60%-80% to the filter efficiency of TPM, the pressure drop of filter stick is up to
To 1.56kPa-2.34kPa.Therefore the strainability space for continuing to improve acetate silk filter tip is extremely limited.
To improve tobacco smoke filter element efficiency, occur adding in filter stick some functional materials reach reduce it is certain in flue gas
The purpose of ingredient.If patent CN101396170 discloses composite cigarette filter stick made of a kind of modified absorbing material granules, can change
Kind cigarette smoking quality simultaneously can remove part harmful components.Patent CN201108028 is by amine based material made from surfactant
It is added in acetate fiber and obtains binary compound filter candle, alternative reduces harmful volatile carbonyl chemical combination in cigarette smoke
Object.The modified porous hydroxyapatite of trimethyl ammonium chloride base acethydrazide is added to acetate fiber by patent CN200920223706
In obtain binary compound filter candle, alternative reduces hydrogen cyanide burst size in cigarette smoke.But these above-mentioned technologies are to cigarette
Suction taste exist it is certain influence, constrain application of these materials in Chinese-style cigarette.
