Abstract
A cigarette is provided which includes a tobacco strand wrapped with a layer of paper having a water repellent impregnation made from a cellulose derivative.
Description
The invention reside in the problem of avoiding on the cigarette paper of cigarette, forming spot.
Cigarette distributors sees the immaculate white appearance of cigarette as quality index.Although this viewpoint is not exclusively right-and cigarette also can variable color after of short duration storage under warm, and this does not influence the demand that smoke-manufacturer must satisfy market.
On cigarette paper, form being explained as follows of spot, promptly at the contact point of makings particle, the tobacco leaf inclusion porous paper of dissolving because cigarette paper be porous be again hydrophilic.
Can imagine, on cigarette paper, add and cover one deck and make any material that paper fully can not be saturating, form with the spot that is reduced on the cigarette paper.Such coating is proposed, to play the effect of extinguishing the cigarette end that abandons fast.In order to control the content of different cigarette inclusions, the cigarette manufacturer is generally interested in certain air permeability of cigarette paper.Thereby problem is, keeps cigarette paper can see through air on the one hand, reduces the permeability to the cigarette composition of dissolving on the other hand.
At US-A5, for addressing this problem, propose to form cigarette paper in 143,099 by two layers of paper, wherein internal layer paper has very high permeability, thereby keeps total permeability enough high.In this article, mentioned adding 0.5% alkyl ketene dimer and made the hydrophobic method of internal layer paper.
Than the prior art of mentioning, the purpose that the present invention is based on is, although make the use of two layers of paper become unnecessary and by macerate, it is harmless and as far as possible little to the change of smoke.
Be unexpectedly, caused the solution of this task, promptly the cigarette paper that cigarette is used comprises that one deck has cellulose derivative, especially the paper of the hydrophobicity impregnate layer of ethyl cellulose.EP0419981 promptly shows a kind of like this cigarette, but air permeability wherein is lower than 5 coresta units.
The understanding that the present invention is based on is to make impregnate layer enough thin, to obtain required air permeability, even it scribbles a lot of layers.By the present invention, also propose to reach at least 20 preferred 50coresta unit at least, the cellulose derivative of coated with multiple layer for the air permeability that makes cigarette paper.
In itself, various cellulose derivative can be satisfied the air permeability of relevant impregnated paper of proposition and the physical condition of impermeability, for example sufficiently high derivatization cellulose ether and cellulose esters (for example NC Nitroncellulose).But preferred, ethyl, because it is safe and harmless-be equivalent to the tobacco leaf regulation of Germany-and change smoke hardly.
Further details of the present invention is then discussed by contrast test.
In low-pressure process, unit are is weighed 26g/m by applicator roll
2Cigarette paper be coated with acetopropion cellulose (CAP) or second fourth cellulose (CAB) or ethyl cellulose (EC).Coated weight is about 0.7g/m
2Produce cigarette with such cigarette paper.
For testing its maculation, the cigarette of packing and unpackaged state is stored at 20 ℃ and 60% relative air humidity or under 30 ℃ and 80% relative air humidity condition.After the production at once and after 24 and 48 hours, measure spot (each 100 cigarette).Estimate spot size and quantity, change the result into dot system through weighting.
Evaluation result is as follows:
Coating 572 points of band 0.7gEC
Coating 223 points of band 0.7gCAP
Coating 77 points of band 0.7gCAB
Although the paper that ethyl cellulose applies demonstrates more intense maculation (height is counted), carried out further exploitation with this material, because aware a kind of undesirable cigarette variation during with CAP and CAB.At least when the paper that uses EC to apply, compare with the paper of coating not and at first to aware less substantially spot rate.But the cigarette of producing after about one month in the paper with the EC coating has shown little stain, bigger yellow spotting then occurs in using the cigarette of coated paper not.To such conjecture be, infiltrated in the paper that its diffusion is subjected to the inhibition of coating at the fault location dyestuff of coating.In view of this consideration, with the paper repeated test that applies twice, promptly use load that 1.4g/m is arranged
2The cigarette paper of EC.Thereby the maculation by the aforementioned calculation method drops to 56 points, promptly compares single coating, has reduced 10 times.This surprised result is being confirmed in the test for a long time.
Benly be, reached above-mentioned effect,, after coating, also have 20 coresta units before coating although the porosity of paper is 50 coresta units.Use first test confirmation as raw material of the paper of higher hole, even when final porosity is 50coresta unit, the present invention also can thoroughly be lowered into spot, and (Coresta unit (CU) expression, how many cm per minute has under the 10cm water column pressure
3Air passes through 1cm
2The area of paper).
