Description
Technical field
The invention belongs to the cigarette material technical field, be specifically related to a kind of novel tow mixing and matching filter tip rod that is applied in the cigarette.
Background technology
Cigarette filter is as the bridge between smoker and the main flume, effective part harmful components in the filtering flue gas, thereby paid attention to widely and use.The cigarette tipping filter tip can improve sucks security, alleviates smoking and healthy contradiction, alleviates the Health cost degree that sucks smog.The experimental results shows, adopts different filter tips to be hinged with on the cigarette, can make coke tar in cigarette reduce 20%～50%.Therefore the countries in the world tobacco business is all employed up-to-date science and technology, constantly makes great efforts the more effective cigarette filter of exploitation, is used to satisfy the special requirement of cigarette industry.
Cigarette filter has the branch of common filter tip, composite filter tip, special type filter tip.Composite filter tip is made up of the filter material that contains two or more, has high absorption affinity, can effectively adsorb T/N in the flue gas, but the manufacturing process more complicated, cost is high, anti-poor processability.Special type filter tip is meant the filter tip that adds some special materials, can have strong adsorptivity to some harmful components in the flue gas, but manufacturing process is complicated, and cost is high, and can bring certain assorted gas into, influences the suction quality of cigarette.Therefore the widest still common filter tip of the scope of application, conventional use mainly contain three kinds of cellulose acetate filter rods, polypropylene fibre filter stick, paper filter stick.Cellulose acetate filter rod can significantly reduce tar content and the nicotine amount in the flue gas, and good hardness behind the filter stick formation, and there is not too big negative effect in stable performance to the cigarette smoking quality, thereby obtains widespread usage.Polypropylene fibre filter stick low price, but filter efficiency is low, and there is negative effect in the cigarette smoking quality; And in the filter stick formation process because of there not being the moulding of better suited tow rod to use adhesive; Cause polypropylene fibre filter stick tow more fluffy, hardness is relatively poor, and its degradation property is relatively poor; Be prone to cause environmental pollution, can only be used for Low-end Cigarettes.The paper filter stick low price; High to the filter efficiency of flue gas, but elasticity, difference of hardness behind the filter stick formation, whiteness is low; Filter stick makes moist softening easily; Also make hamony and the assorted gas aspect of cigarette have bigger defective, therefore the single paper filter tip rod market of fading out gradually only is applied in the composite filter tip.
But present research only concentrates on the specification adjustment of tow and to its modification aspect, promptly is intended to carry out surface modification through the adjustment strand specification with to tow, thereby improves the whole macroscopical strainability of filter stick.Carry out surface modification through the adjustment strand specification or to tow, improve the filter efficiency to flue gas, the effect of this measure is extremely limited.At first along with the strand specification adjustment, adopt low dawn tow, monofilament linear density reduces, and the draw resistance of cigarette raises, and lets the consumer be difficult to accept; Secondly; Single tow structure evenly distributes fiber, and every fiber is consistent to the intrinsic adsorption capacity of flue gas; Just there be of the absorption supersaturation of some fiber to flue gas composition; And some fiber is to the absorption undersaturation of flue gas composition, even basic not absorption, thereby the raising of filter efficiency also is very limited; Be exactly single tow structure in addition, in the filtering harmful components, flavor component makes flue gas reduce smoker's satisfaction also by interception significantly.
For the microcosmic aspect, be in the performance of the single fiber of diverse location in the filter stick and the research of effect and do not appear in the newspapers.Chinese patent ZL96119261.5 discloses a kind of cigarette filter; Can be through will having fabric construction and comprise a kind of cellulose ester short fiber and a kind of viscose fibre of from the one group of material that comprises polysaccharide or derivatives thereof and biodegradable polymer, selecting, this viscose fibre system is shaped to bar-shaped by the stratified material that has blocking characteristics for said short fiber and obtains.The various cellulose esters that belong to cellulose ester short fiber have simply been mentioned in this patent; Can separately or mix the back and process filter tip with layer structure with viscose fibre; And how to mix for various cellulose esters, need reach which kind of technical standard and no requirement (NR) after the mixing.This technology increases making on the microcosmic on the single fiber strainability; Thereby the strainability of filter stick is improved; But it does not consider that fiber present position in filter stick is different, and it acts on different factors; Make filter stick descend, lack selectivity all flue gas composition uniformity.
Therefore; Consider the performance of diverse location single fiber in the filter stick; And interfibrous interaction, bring into play the adsorption capacity of fiber to greatest extent to flue gas, reduce suction-operated to fragrance component; This is an important directions of tobacco business development cigarette filter just, but does not see that as yet report is arranged in the at present relevant technology in this respect.And the present invention is directed against demand in this respect just; According to the performance of diverse location single fiber in the filter stick, and interfibrous interaction, in conjunction with the demand of cigarette design and Chinese style cigarette; According to the motion state of flue gas in filter rod and the distribution form in filter rod thereof; From emphasis, mechanism and the effect of filter rod diverse location bunch fiber to the flue gas effect, developed a kind of novel tow mixing and matching filter tip rod, the evidence effect is good.

Operation principle of the present invention:
Research shows that the tow filter rod mainly is that cigarette filter rod filters the mechanicalness of flue gas granule phase substance to the effect of flue gas, and its mechanism of action is: directly interception, inertial collision and diffusion deposition.
Flue gas is considered to the aerosol that viscous drop constituted that surrounded by gas and steam usually.According to existence, motion and the version of flue gas aerosol in cigarette filter tip rod; Flue gas is under the influence that receives composite factors such as Brownian movement, extension, molecular free path, molecule or particle size in various degree, and can there be regularity distribution in the flue gas material composition.In view of molecule or particle size (or hydrodynamics), molecule that size is big or particle are because its extension is poor, and inertia is big, focuses mostly in the central authorities of filter stick; And little molecule or the particle of size, because of its extension is good, molecular free path is little, and Brownian movement fiercenesses etc. are prone to diffuse to the edge of filter stick.In view of material was formed, filter stick central authorities aerosol particle concentration was higher, and micro-molecular gas such as filter stick edge C O, low molecule aldehyde ketone are easy to arrive through modes such as diffusions, and the half volatile material is between grain phase part and micro-molecular gas.Therefore from practicality, should be to concentrate to have in a large number the grain phase component is had the fibre bundle than the specification and the material of strong filter performance in the optimal design of filter stick central authorities; Optimal design should be to concentrate to have in a large number pernicious gas molecules such as CO, low molecule aldehyde ketone are had strong affinity at the filter stick edge, or helps its fibre bundle to the specification and the material of external diffusion; The optimal design of ring belt for being added between filter stick central authorities and the edge should be to concentrate to have a large amount of double escaping gas not have strainability; Or have only the specification of low strainability and the fibre bundle of material, so that the cigarette flavor component can not produce too big decay.Certainly, from flexibility, also will combine the demand of cigarette design, like balance flue gas composition, the variation of control resistance to suction etc., each different position needs the fiber of which kind of specification and type on earth in next concrete definite filter stick.
According to this theory, the present invention not only efficiently solves some difficult problems in the present tow filter rod technology, also can adjust according to the different needs of cigarette design simultaneously, and design brings bigger flexibility and applicability to cigarette.Same kind different size tow is carried out blending; Or the tow of dissimilar specifications of the same race carried out blending; Or dissimilar different size tow are carried out blending; Can obtain a series of novel tow filter rods: on the disc that with the axle center is the center, forming the mixed distribution of unlike material tow, can be that the unlike material tow forms evenly distribution on fiber number, also quantitatively forms the distribution that gradient increases or reduces along the axle center to the material bunch fiber of the same race of circumferencial direction; Or on the annulus that with the axle center is the center, form the distribution of material of the same race; On the disc that with the axle center is the center, forming the mixed distribution of different monofilament linear density tow, can be the even distribution that on the disc that is the center, forms different monofilament linear density tow with the axle center, also can be on monofilament linear density, to form the distribution that gradient increases or reduces along the axle center to circumferencial direction; Or on the annulus that with the axle center is the center, form the distribution of monofilament linear density tow of the same race; Can increasing along with the increase monofilament linear density of annular radii, also can reduce along with the increase monofilament linear density of annular radii, also can be irregular random distribution.
The present invention is in the application that combines the cigarette design requirement, and is comparatively flexible, comparatively practical.As: if will reduce T/N, can sneak into low dawn specification or T/N is had the fiber of affinity material type by force in filter stick central authorities; If to increase little molecule pernicious gas to external diffusion, can sneak into high dawn tow at the edge of filter stick; If will strengthen cigarette flavor concentration or main flume moisture, can on the ring belt between filter stick central authorities and the edge, sneak into high dawn specification or double escaping gas or have than the fiber of low-affinity material type etc. moisture.
Characteristics of the present invention:
(1) novel tow filter rod provided by the invention helps the efficient interception of a phase component when filtering flue gas, helps the interception or the diffusion of gas oxious components such as CO; Help the reservation of fragrance ingredient, help the raising of main flume moisture, given full play to the maximum effect of every fiber; Can be according to the demand of cigarette design; Exhaust gas components is tackled targetedly or kept, and its excellent selectivity is given this novel filter stick better flexibility and practicality.
(2) fiber of unlike material is different to the selective absorption result of cigarette harmful components; But the tow of most materials is difficult to satisfy the moulding process of filter rod because of there not being suitable manufacturing methods, thereby has limited their application, popularization; Like polypropylene fibre etc.; Novel tow filter rod provided by the invention after pressing certain regular blending to this type tow and acetate silk, adopts present acetate fiber plasticizing agent; Solve this difficult problem well, thereby promoted selection, application and the popularization of tencel tow.
(3) its preparation process of the present invention is simple, and is easy to operate feasible.
