Description

A kind of cigarette with binary composite tip stick and preparation method thereof
Technical field
The present invention relates to cigarette, more particularly, the present invention relates to a kind of cigarette with binary composite tip stick with the mouth rod.Simultaneously, the invention still further relates to the preparation method of this cigarette.
Background technology
Progress along with social civilization, healthy and environmental protection becomes the focus that people pay close attention to, in the face of pressure from government and social each side, tobacco business is in order to seek survival, to seek development, the cigarette manufacturer of various countries adopts the technology of aspects such as chemistry, biology and physics in succession, carry out the development of low tar, low harm cigarette in all directions, obtained a large amount of scientific achievements.
2002, people such as Paschke quote nearly 200 pieces of various documents and materials, to the relevant cigarette carried out over the years with the reducing tar and reducing harm additive carried out comprehensively, the system documentation summary, comprise that application of active carbon, diatomite, molecular sieve etc. make composite tip stick, reduce harmful substances such as condensed-nuclei aromatics in the cigarette smoke, TSNA; Also comprise the plant extraction liquid that adds antioxidant such as polyphenols, the free radical in the removing cigarette smoke etc.; The author points out that also most research is only limited to the laboratory simultaneously.People such as Xue have studied the influence of materials such as active carbon, silica gel, resin to the absorption of single port flue gas, and for 26 components will adsorbing, the charcoal absorption effect is best; Silica gel then has obvious effect to polar component such as aldoketones; Resin is obvious to arene compounds such as BaP effect.
In addition, by selecting suitable leaf group, add the combination of mouth rod, obbbin, tipping paper, tar can reach different requirements substantially at present, because the smoke components that major part is considered to be harmful to mainly is present in the granule phase substance, when therefore reducing tar, these smoke components are also with regard to corresponding minimizing, as nitrosamine, BaP etc.But abovementioned technology does not all have effect to CO, the reduction effect of carbon monoxide and not obvious in the flue gas, and this mainly is the physico-chemical property owing to CO itself, it can not effectively be filtered by existing filter tip.Therefore, to how reducing carbon monoxide in the cigarette smoke, still need to proceed deep research.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, avoid the limitation of existing cigarette filter tip, a kind of carbon monoxide and other harmful substance that can effectively reduce in the flue gas is provided, do not influence the cigarette of the band binary composite tip stick of the quality of bleeding simultaneously again.Another object of the present invention provides the preparation method of the cigarette of described band binary composite tip stick.
Purpose of the present invention is achieved by following technical proposals.
The invention provides a kind of cigarette with binary composite tip stick, this cigarette comprises pipe tobacco section and mouth rod, and the core of mouth rod adopts cigarette diacetate fiber tow; Described mouth rod is by the outer section of lip end and pipe tobacco end inner segment binary compound composition; The outer section of described lip end is identical with the length of pipe tobacco end inner segment, but both have different resistance to suctions, and outer section is 10~250 millimeters of water with the resistance to suction difference of inner segment; Wherein, can be that the section resistance to suction also can be that the inner segment resistance to suction is greater than outer section resistance to suction greater than the inner segment resistance to suction outward.
The forming paper of described mouth rod is that air permeability is the yew paper of 6000cu, and is provided with laser boring in the position of 10~12 millimeters of distance lip end faces, and the forming paper of described pipe tobacco section is that air permeability is the regular-size cigarette paper of 300cu.
The invention provides the preparation method of the cigarette of band binary composite tip stick, this method adopts following steps:
(1) core of the basic mouth rod of selection
The core of basis mouth rod adopts cigarette diacetate fiber tow, and strand specification is selected from a kind of among 1.8Y/35000,1Y/35000,2.2Y/34000,2.4Y/32000,2.4Y/34000,2.4Y/35000,2.7Y/35000,3.0Y/30000,3.0Y/35000II type, 3.0Y/35000,3.0Y/37000,3.0Y/39000,3.3Y/30000,3.3Y/35000,3.3Y/37000,3.3Y/39000,3.5Y/35000,3.9Y/31000,4.1Y/35000,4.8Y/35000,5.0Y/35000,5.4Y/35000 or the 6.0Y/35000; Wherein, the shape of cross section of Y type tow is " Y " shape, and fiber specific surface area is big, and the harmful components in the cigarette smoke are had absorption and crown_interception preferably; Filament denier is the single weight in grams numerical value that does not add 9000 meters curling length silks; Total denier i.e. one group of quality gram numerical value that does not add 9000 meters curling length silks;
(2) make basic mouth rod
According to the determined resistance to suction scope of acetate silk self-characteristic curve that acetate fiber factory provides, carry out the processing of basic mouth rod and obtain acetate fiber mouth rod; The basic nozzle rod sucting resistance scope that processes is in the determined scope of characteristic curve; Described 23 kinds of mouth rods have 23 different best nozzle rod sucting resistance ranges of work; Adopt existing P M5N/AF2/TF3 type wire-beam forming equipment, through the tow shredding, add plasticizer, wire-beam forming, seal and cut and obtain basic mouth rod; The length of described basic mouth rod is 120mm, and circumference is 24.2mm;
The basic mouth rod that (3) will prepare is combined into binary composite tip stick
The basic mouth rod that will have different resistance to suctions is arranged in pairs or groups, and the resistance to suction difference of mouth rod internal and external section basis mouth rod is 10~250 millimeters of water; The air permeability scope of composite tip stick forming paper is 1000~10000cu; Mouth rod equipment complex is DR2-5; Slivering is cut, makes up, sealed to base bars, cut into required composite tip stick again; The resistance to suction scope of composite tip stick is 200~500 millimeters of water, and length is 20mm;
(4) rolling cigarette
Adopt conventional method, will be cut to the long composite tip stick tipping of 20mm on the pipe tobacco section, promptly obtain the cigarette of band binary composite tip stick of the present invention by the cigarette machine branch; Wherein, the forming paper of described mouth rod is that air permeability is the yew paper of 6000cu, and gets air-vent in the position of 10~12 millimeters of distance lip end faces with laser, and the forming paper of described pipe tobacco section is that air permeability is the regular-size cigarette paper of 300cu.
Compared with prior art, the present invention has following beneficial effect:
Because mouth rod outer section resistance to suction and mouth rod inner segment resistance to suction exist resistance to suction poor, adopt laser boring on the yew paper of mouth rod, realize the purpose that filter tip ventilates.The present invention is skillfully constructed, the mouth rod of special construction has been obtained existing mouth rod and has been comprised common binary mouth rod, the inaccessiable effect of ternary mouth rod, can selectively reduce carbon monoxide and other harmful substance, make cigarette carbon monoxide/tar ratio, not influence the quality of bleeding again less than 1.The conventional cigarette smoke analysis result of annual reference substance in 2004 sees Table 1.
