Abstract
The utility model relates to a filter candle and a filter tip with an activated carbon fiber layer. The utility model comprises a cellulose acetate core (3), an activated carbon fiber layer (1) which is winded outside of the cellulose acetate core (3) and an outer cellulose acetate core (2) which is winded outside of the activated carbon fiber layer (1). The activated carbon fiber layer is provided between the cellulose acetate core and the outer cellulose acetate core and is added into the filter candle and the filter tip of the utility model. Thereby, the activated carbon fiber layer is fixed without easy desquamation. Absorbing abstractions of the filter candle and the filter tip are same, which effectively reduces the volatile and the sub-volatile harmful substances in the main smoking such as nitrite, benzopyrene, cypress oil and the like. Further, the activated carbon fiber layer added into the filter candle and the filter tip has the function of counterfeit deterrence.
Description
Technical field
The utility model relates to filter stick and the filter tip that a kind of cigarette filter is used, and particularly has the filter stick and the filter tip of NACF layer.
Background technology
At present, along with growing to even greater heights and the generally enhancing of consumer of the anti-cigarette motion in the world to smoking and health perception, the pressure that tobacco business faces is increasing, when tar and harmful components thereof were reduced, keeping cigarette odor-absorbing to make the consumer obtain that physiology satisfies again was the ultimate challenge that the cigarette design faces.Cigarette filter stick 90% is made up of single acetate fiber at present, though some patent disclosure form by the filter stick of a section or plurality of sections carbon-point and a section or plurality of sections cellulose acetate, form but just arrange mutually between carbon rod in this filter stick and the acetate fiber rod, therefore in Cigarette and filter stick cohesive process, carbon rod comes off easily, and one section is carbon rod in filter stick, one section is cellulose acetate, flue gas is different with the resistance to suction of passing through the acetate fiber rod by the resistance to suction of carbon rod, so the adsorption capacity of carbon rod reduces greatly.
Summary of the invention
The purpose of this utility model is to reduce tar and harmful components thereof in the cigarette smoke further, and a kind of filter stick and filter tip that has the NACF layer is provided.
The utility model is achieved through the following technical solutions:
A kind of filter stick that has the NACF layer of the present utility model, it comprises: the cellulose acetate core, be wound on NACF layer that the cellulose acetate core outside has and the outer layer of cellulose acetate that is wound on the NACF layer outside;
A kind of filter stick that has the NACF layer of the present utility model, wherein: described NACF layer and outer layer of cellulose acetate are reeled with the cellulose acetate core is concentric;
A kind of filter stick that has the NACF layer of the present utility model, wherein: the diameter of described cellulose acetate core is the 0.5-3 millimeter;
A kind of filter stick that has the NACF layer of the present utility model, wherein: the thickness of described NACF layer on diametric(al) is the 0.2-0.5 millimeter;
A kind of filter stick that has the NACF layer of the present utility model, wherein: the length of the NACF in the described NACF layer is the 2-5 millimeter;
A kind of filter tip that has the NACF layer of the present utility model, wherein: it comprises: the cellulose acetate core, be wound on NACF layer that the cellulose acetate core outside has and the outer layer of cellulose acetate that is wound on the NACF layer outside;
A kind of filter tip that has the NACF layer of the present utility model, wherein: described NACF layer and outer layer of cellulose acetate are reeled with the cellulose acetate core is concentric;
A kind of filter tip that has the NACF layer of the present utility model, wherein: the diameter of described cellulose acetate core is the 0.5-3 millimeter;
A kind of filter tip that has the NACF layer of the present utility model, wherein: the thickness of described NACF layer on diametric(al) is the 0.2-0.5 millimeter;
A kind of filter tip that has the NACF layer of the present utility model, wherein: the length of the NACF in the described NACF layer is the 2-5 millimeter.
The utlity model has following remarkable advantage:
The utility model is added with in filter stick and filter tip and is wrapped in cellulose acetate core and the middle charcoal fibrage of outer acetate fiber layer, therefore the NACF layer is not easy to come off, filter stick is identical with filter tip resistance to suction everywhere, the harmful substance that can reduce volatility and half volatile in the main flume most effectively is as nitrosamine, BaP, tar etc., and is added with the NACF layer also has false proof function in filter stick and filter tip.
