Description
Technical field
A kind of chitin modified cigarette belongs to the preparing technical field of cigarette filter with the production method of diacetate fiber tow.
Background technology
Cigarette produces a large amount of chemical substances and mainly is present in the aerosol in combustion process, aerosol is divided into gas phase part and part mutually again.Gas phase partly accounts for 92% of whole flue gas weight, steam comprising organic matter and inorganic matter, excessive nitrogen (about 58%), oxygen (about 12%), carbon dioxide (about 13%), a spot of hydrocarbon, oxygenatedchemicals and other compositions, and contain the material of biologically active.Harmful components in the gas phase mainly contain carbon monoxide, hydrogen cyanide, volatile aldehyde material, volatile nitrosamine, nitrogen oxide, pyridine and gaseous phase free radical etc.The grain that accounts for whole flue gas weight 8% partly mainly is made up of nicotine, tar and moisture mutually.Nicotine (nicotine) has strong impulse and paralysis effect to people's nervous centralis, makes people's excitement on a small quantity, can cause in a large number dizzy, vomit even be poisoned to death.Exist in the tar and bring out the material of cancer, wherein 0.2% is carcinogenic initator, the 0.4%th, and carcinogenic synergist.The former can change the genetic structure of cell, makes normal cell become cancer cell; The latter itself can not change the genetic structure of cell, but can stimulate the cell that is excited, and causes the development of tumour.Carcinogen in the tar mainly is some polycyclic arene compounds, and they are tobaccos when burning pyrolysis forms, and benzo [a] pyrene with strong carcinogenesis can be used as representative wherein.Therefore, smoking and health problem are the problems that tobacco business is endeavoured to solve always.
Occurring in nature, chitin extensively is present in the cell of rudimentary plant mushroom, algae, the shell of arthropod shrimp, crab, fly maggot and insect, shell and the cartilage of shellfish, mollusk (as squid, cuttlefish), the cell membrane of higher plant etc., its annual biosynthetic stock number is the second largest living resources that are only second to string on the earth up to 10,000,000,000 tons, wherein halobiontic growing amount can be described as a kind of nexhaustible living resources more than 1,000,000,000 tons.
Chitin can be obtained soluble chitin---shitosan with highly basic deacetylate under heating condition.Shitosan system white or faint yellow chip solid, English name: Chitosan is called for short CTS, and its chemical name is: polydextrose amine (1,4-2-amido-deoxidation-β-D glucose).In chitosan molecule, have amino and hydroxyl, they all have the coordination chelating function, can form complex with transition metal ions and have the function of the absorption selected, simultaneously all can connect skill and reticulate polymer with crosslinking agent, be dissolved in the diluted acid and can form full-bodied colloidal substance, its aqueous solution is cationic polyelectrolyte, has good flocculation.The amino of shitosan has the cation exchange function, when pH＜6.5 high charge density is arranged, and can be adsorbed on negative charged surface, with many metal ion-chelants.Shitosan has excellent biological compatibility and biologically active, and is nontoxic, is easy to biodegradation.
Summary of the invention
The purpose of this invention is to provide the production method of a kind of chitin modified cigarette,, improve the filter effect of cigarette filter to reduce oxious component in the cigarette smoke with the diacetate fiber tow.
Technical scheme of the present invention adopts chitin modified cigarette with the method for diacetate fiber tow to be: to select for use shitosan that cigarette is carried out modification with the diacetate fiber tow; In the spinning unit of cigarette, in oil groove, place a kind of compound finish that contains shitosan and hydrophilic surfactant active and form homogeneous latex emulsion with the diacetate fiber tow production process; In the process of oiling, shitosan is attached to diacetate fiber tow surface.
Select for use the technical indicator of shitosan to be:
Used shitosan comprises the shitosan of common shitosan or different deacetylations.Because the deacetylation of shitosan has significant effects for its filtering effect to harmful substance in the flue gas, deacetylation is big more, and is high more for the filter efficiency of nicotine and tar, and deacetylation is that 95% shitosan effect is best.
Adding shitosan to form homogeneous latex emulsion in the compound finish specification requirement comprises:
Consisting of of used compound finish, the commercially available T90 finish of 5-10% adds the shitosan dilute acetic acid aqueous solution of 90-95%, and the shitosan dilute acetic acid aqueous solution is that the shitosan of 4-10 ‰ mass percentage concentration is dissolved in the aqueous acetic acid of 1-3% mass percentage concentration.
Mixed system basic composition is 7% commercially available T90 finish, and (5 ‰ shitosan spirit of vinegar (2%) aqueous solution of 66% mineral oil+5% water+29% surfactant (lipophile: hydrophily=5.5: 1))+93%, the compound finish effect of being formed is best.
Beneficial effect of the present invention: the present invention adopts shitosan that cigarette is carried out modification with the diacetate fiber tow, to realize that reducing tar and reducing harm is a target, cigarette after the modification obviously improves with the removal effect of diacetate fiber tow to main oxious component in the cigarette main flume, and these oxious components mainly comprise total particulate (TPM), nicotine, tar, polycyclic arene compound, benzo [a] pyrene, volatile fat aldehydes and free radical etc.The innovative characteristics of this method is: (1) method in the past is that solid grain phase additive directly is added in the filter tip, and it is stable to be difficult to ensure the quality of products.This method is made liquid back to additive and is combined with producing the worker, and technology is simple, and stability is fine; (2) shitosan can carry out selective absorption to harmful substance, and itself is harmless, and still a kind of environment-friendly material can not cause secondary pollution; (3) the diacetate fiber tow of the present invention's production has good antibacterial performance, is beneficial to storage, the transportation of tow, has simplified the technical process of adding other antiseptic in general tow production and the use.
Cigarette is one of of paramount importance cigarette material of China with the diacetate fiber tow.The achievement in research of this patent not only can improve the process technology level of cigarette with diacetate fiber tow industry, the diacetate fiber tow is appreciated and enlarged, and owing to adopt the diacetate fiber tow preparing of the present invention's preparation to become cigarette filter rod, tar class harmful substance in the energy effectively catching cigarette smoke, improve the cigarette class, alleviate smoking and healthy contradiction, therefore, have important society and environmental benefit.
Employing is carried out in flue gas total particulate (TPM), nicotine and tar filtration as cigarette filter to cigarette through chitin modified diacetate fiber tow, and its removal effect sees Table 1.
