Abstract
The invention provides a composite filament strand filter tip for cigarettes. The filter tip is composed of mixed fiber filament strands which are formed by blending cellulose acetate filament strands and degradable functional fiber filament strands, wherein the total denier ratio of the cellulose acetate filament strands to that of the functional fiber filament strands is (5-3.1):1. Since the denier ratio of the cellulose acetate filament strands and the functional fiber filament strands is better, when glyceryl triacetate is used for forming, the filter tip is more excellent in usability and processability such as adhesion effect, hardness and draw resistance to meet the requirements of the cigarettes. Due to improvement of the functional fiber proportion, the filter tip is more effective in selective adsorption and balance adsorption of harmful substances and. Further, the technological base is provided for use of various functional fibers as filter tip materials.
Description
Technical field
The invention belongs to the smoking material technical field, be specifically related to a kind of cigarette with compound tow filter rod.
Background technology
Can produce 5000 number of chemical materials behind the cigarette imperfect combustion, wherein the overwhelming majority is aroma component, and approximately 0.6% is harmful components, comprises 44 kind of 13 class hazardous compound during flue gas gas phase and condensed particulate are mutually.Nuisance in the gas phase mainly contains carbon monoxide, nitrogen oxide, volatile aromatics, hydrogen cyanide, volatile aldehyde and ketone etc., and grain mutually middle nuisance mainly is condensed ring aromatic hydrocarbon, N-nitrosamine, aldehydes matter, free radical, heterocyclic compound, heavy metal and radioactive substance etc.Tarry matters in smoke are main bodys of granule phase substance, and wherein condensed-nuclei aromatics has carcinogenesis, such as BaP, hexichol pyrene, dibenzanthracene etc., have formed the main murder by poisoning thing of smoking; Nicotine is called again nicotine, is nitrogenous alkaloidal main component in the tobacco, human heart, brain and tracheae is had very large toxicity, and make people's habituation; Can be combined by the hemoglobin in blood by the carbon monoxide that the tobacco imperfect combustion produces, cause the body anoxic, cause poisoning.Therefore, world's Main Developed Countries has all been formulated running water to the tar in the cigarette smoke, nicotine and carbon monoxide at present.The cigarette tipping filter tip can reduce smoking largely to the injury of health, shows the grain phase of filtering in the flue gas and adsorbs these two aspects of harmful components in the flue gas gas phase.How to filter selectively and adsorb harmful substances from flue gases, and keep the long term object that harmless fragrance component is the tobacco technical development.
The primary structure of cigarette filter rod (being filter tip) is tow, and these tow are comprised of the curling single fiber of some, certain fineness, are bar-shape, are rolled into column after applying plasticizer or adhesive, and paper using is rolled into filter stick again.Desirable one-tenth rod tow has moderate mechanical strength and elongation, is convenient to cut off processing; Nontoxic, tasteless, do not affect the smoking taste; Filter efficiency is high; Moderate; Can be biodegradable.
The CN201813837U Chinese utility model patent discloses a kind of composite tip stick, formed by composite filter element, interior integument and outer wrapping layer three part, wherein composite filter element is divided into the acetate silk section, adds the expanded cabo particle section and adds three sections of mint particles sections and is formed by connecting, this composite filter tip can reduce the harmful substances such as hydrogen cyanide in the main flume, crotonaldehyde, phenol, and promotes the cigarette smoking quality; The disclosed technology of application number 200910060795.4 Chinese invention patents is to adopt polyvinyl alcohol or polyethylene glycol, delustering agent, coupling agent, rheology control agent and polypropylene mixing granulation, the water-soluble part water soluble polymer that goes of spinning after heat, obtain the loose structure tow, can reduce tar and volatilizable Carbonyl compounds in the flue gas.
All filter sticks all have physics in various degree to hold back or filtration to fume damage, and specific area, crimpness and the tow tight ness rating of fiber can make tar reduce 20%-50% in the control filter stick; Chemisorbed characteristic based on tow self can further be removed the murders by poisoning such as carbon monoxide in the flue gas, nitrogen oxide, volatile aromatics, hydrogen cyanide, volatile aldehyde and ketone.The principle of chemisorbed is the compatibility of bunch fiber and flue gas gas phase nuisance, show as Van der Waals force, hydrogen bond, soda acid interaction etc. at molecular level, need to consider tow polymer and the hydrophile-lipophile balance value, the pH-value equimolecular characteristic that are adsorbed nuisance.Thereby high adsorption function tow becomes the most promising direction and focus of novel filter tip research and development.
At present, the used filter tow of tobacco mainly contains Celluloseacetate cigarette filter tow and polypropylene tows two large classes.
The substitution value of acetate fiber is 2.3-2.6 approximately, mean on cellulosic backbone and 2.3-2.6 hydroxyl on average arranged by acetic acid esterified in 3 hydroxyls of each glucose unit, have preferably hydrophobicity and part hydrophily, can adsorb most of flue gas nuisances, become the main flow tow that medium-to-high grade cigarette filter adopts, its consumption accounts for pipe tobacco market more than 90%.But, the acetate silk selling at exorbitant prices; The raw material of wood pulp of acetate fiber still needs a large amount of imports; And for absorption polarity nuisance, such as hydrophiles such as hydrogen cyanide, nicotine, volatile aldehyde ketones, the hydrophily of acetate fiber is also not enough.Along with people to the further concern of smoking health and the year by year raising of national relevant laws and regulations, acetate silk still need improve fume damage thing filter efficiency.
Polypropylene tows is held back very few to tar, it is essentially nonpolar, be limited to Van der Waals force with the absorption of flue gas gas phase nuisance, most of nuisances are lacked chemisorbed, easily nicotine being held back too much affects the cigarette mouthfeel, and fracture strength and elongation are large, easily the thermal change type, curling variation is large, without suitable plasticizer and its coupling.Therefore, the third fibre can only be as economy cigarette filter material.
Except above-mentioned acetate fiber and polypropylene fibre for cigarette filter rod, also have some fibre that a large amount of production and application are industrially arranged, and price is suitable.Such as viscose rayon, fibre and soya, vinal and the glass fibre etc. that or are used on clothes and the fabrics for industrial use.Many reports about new type functional fiber and preparation method thereof are also arranged in addition, such as the product of the records such as CN101144206B Chinese invention patent " a kind of micropore polyester fibre and preparation method " in the published lot of documents.Researcher's discovery of this patent, these fibers have better effect equally in the special harmful components of removal flue gas, and their preoriented yarn (being called for short POY) through after curling, has good flue gas absorption property as filter tow.
The important research direction that improves at present the cigarette holder filter effect by fibre bundle being carried out modification or in filter stick, adding several functions sex pilus bundle by blended weave, particularly adopt mixed fine technology to form tow, the weakness of individual fibers can be remedied by other fibers, has increased thus the scope that the filter tow fiber is selected.
For example, the CN101624729B Chinese invention patent adopts polypropylene and vinyl acetate co-polymer and solubility polyester co-blended spinning, alcoholysis and hydrolysis in pure aqueous slkali after stretched, again through the washing after curling drying, make hydrophilic porous type filter tow, improve the filter effect to harmful substance.
As the cigarette filter fiber, at first to satisfy to greatest extent the performance requirement of holding back, filter, adsorb harmful substances from flue gases, it is less important to satisfy the technology requirement that bunch fiber is bonded into rod.Under existing process conditions, since harsh to filter stick tow bond condition, cause many functional fibers can not be used for filter tip production, be used for the functional fiber that filter stick is made, also have no the filter tip filter effect between them after the blending and have clear improvement.
For example the technology that discloses of application number 200410065071.6 Chinese invention patents is in to cigarette acetate silk complement wire process, add into the viscose that can eliminate harmful substance, carbon fiber, vinal, Lyocel fiber or Tencel fiber, additional amount is 1% ~ 3%, its cigarette holder is than reducing CO approximately 15% in the common filter tip main flume, free radical reduces approximately 30%, tar reduces approximately 35%, and nitrosamine reduces approximately 35%.But from the angle of the various flue gas nuisances of equilibrium adsorption, so other little fiber additional amounts also are nowhere near.One or more ratios in 10% ~ 90% that the CN101283838A Chinese invention patent discloses in acetate fiber, polypropylene fibre, polyester fiber and the regenerated fiber of different tow types are carried out blending, make along the axle center by moulding process at last and form the cigarette filter tip rod that different densities distributes, unlike material distributes to circumference.But, from the angle of filter stick formation, can not reach with triacetyl glycerine the requirement of filter stick for cigarettes as forming agent, can not solve the effect of selective absorption harmful substance.
