Description
Technical field
The present invention relates to a kind of filter tip for smoking product, this filter tip comprises one section of filtering material, and this section of filtering material comprises regenerated celulose fibre and cellulose acetate fibre and triacetin.The invention still further relates to a kind of filter tip for smoking product, this filter tip comprises one section of filtering material, and this section of filtering material comprises regenerated celulose fibre and low molecular polyether.The present invention also prolongs and for comprising this filter-tip smoking product.
Background technology
Cigarette with filter tip generally includes the column tobacco rod and cylindrical filter mouth that are made up of tobacco filler material, and the packaged paper bag of tobacco rod encloses, filter tip and the axially aligned end-to-end link of wrapped tobacco rod.Cylindrical filter mouth generally includes the filtering material enclosed by filter stick formation paper bag, is generally acetate silk.By convention, the tobacco rod be wrapped and filter tip are connected by tipping paper tape, and tipping paper tape is made up of cellophane paper material usually, surround the adjacent part of filter-tip whole length range and the tobacco rod be wrapped.
In the prior art, someone proposes some smoking products, and in these smoking products, pipe tobacco is heated instead of burns.In hot type smoking product, the matrix (e.g., pipe tobacco) being produced fragrance by heating energy can produce aerosol.Known hot type smoking product such as comprises electric heating type smoking product and produces aerocolloidal smoking product by heat transfer (aerosol that heat passes to physical separation from ignitable fuel composition or thermal source is formed material).In smoking process, by coming from the heat trnasfer of propellant composition, volatile materials produces matrix from aerosol and discharges, and is carried in the air be inhaled in smoking product.When the material cooling discharged, the aerosol that condensation is sucked by smoker with formation by they.In some smoking products, the aerosol containing nicotine can be produced from tobacco material, tobacco extract or other source of nicotine, and not need burning or heating; These smoking products are also known.
Summary of the invention
Suck smoking product, after being abandoned by remainder, need filtration fraction to degrade as quickly as possible.Therefore, need to provide a kind of filter tip for smoking product that can promote degraded.
According to a first aspect of the invention, provide a kind of filter tip for smoking product, this filter tip comprises one section of filtering material, and wherein, this filtering material comprises regenerated celulose fibre and the cellulose acetate fibre of random orienting.This filtering material also comprises triacetin, and this filter tip also comprises the packaging material surrounding this section of filtering material.
The term " regenerated celulose fibre " used in literary composition means, the cellulose fibre with required physical characteristic be formed by processing naturally occurring cellulosic material.Typical method for the formation of regenerated celulose fibre comprises the following steps: naturally occurring cellulosic material (e.g., wood chip) is pounded pulpous state to form slurry; One or more process is carried out to change cellulosic physical characteristic to this slurry; And, forming regenerated celulose fibre by the slurry be processed, such as, being spun into cellulose fibre by allowing slurry pass spinning head.
Advantageously, the degradability by using the filtering material comprising the regenerated cellulose of random orienting can improve filtering material.Reason is, especially compared with the fiber of the filter-tip basic continous of traditional acetate silk, the fiber of random orienting can more easily disperse after filter tip is dropped.The degree of scatter of fiber improves, and will increase each fiber and expose aerial degree, thus improve the degradation speed of filtering material.
In addition, although use regenerated celulose fibre in filtering material, compared with traditional acetate silk filter tip, similar taste will be provided to smoker according to filter tip of the present invention.The reason that can produce the similar sense of taste there is cellulose acetate fibre and triacetin binding agent according in filter-tip filtering material of the present invention.In addition, when triacetin to be bonded on cellulose acetate fibre to improve the structural intergrity of filtering material, triacetin is not bonded on regenerated celulose fibre, thus keeps the degradation effect of this enhancing of filtering material.
Inventor recognizes, compared with traditional cellulose acetate filter mouth, the filter tip only comprising regenerated celulose fibre can not reach identical selective Adsorption of Phenol degree in smoking process.Therefore, have in the filter tip of regenerated celulose fibre by cellulose acetate fibre and triacetin are joined, like this, just can address this is that according to filter tip of the present invention.
The weight content of the triacetin in the filtering material of filter segments is preferably roughly 1% to 15%, is more preferably roughly 5% to 10%, is most preferably roughly 3% to 5%.
In certain embodiments, this filtering material also comprises low molecular polyether, to improve the ability of filter tip optionally adsorbing phenol in smoking process further.Suitable polyethers is polyethylene glycol.Preferably, the mean molecule quantity of polyethylene glycol roughly between 200 to 3600, preferably roughly between 400 to 1600.
The effect of the filtering material using low molecular polyether to improve the regenerated celulose fibre comprising random orienting optionally adsorbing phenol itself is a kind of novelty, design ingenious.Therefore, according to a second aspect of the invention, provide a kind of filter tip for smoking product, this filter tip comprises one section of filtering material, and this filtering material comprises regenerated celulose fibre and the low molecular polyether of random orienting.This filter tip also comprises the packaging material surrounding this section of filtering material.
As discussed above, low molecular polyether is joined in filtering material, raising filtering material is optionally sucked the effect of phenol.Under use regenerated cellulose filter tip replaces the filter-tip situation of traditional acetate silk, this is vital, and such as, reason is that the effect of regenerated celulose fibre optionally adsorbing phenol is not as traditional acetate fiber.Example shown in table 1 below illustrates, uses low molecular polyether can improve the effect of regenerated cellulose filter tip selective absorption phenol.
Table 1: traditional cellulose acetate filter mouth, regenerated cellulose (Lyocell fibers (Lyocell, disappearing fibre)) filter tip and regenerated celulose fibre (Lyocell fibers (Lyocell))+polyethylene glycol (PEG) filter tip adsorb the effectiveness comparison of different phenol.These data representations, through the amount (that is, not being filtered the phenol amount of mouth absorption) of filter-tip often kind of phenol during smoking.These data are also standardized process through filter-tip nicotine content relative in smoking process.Use and collect these data according to the smog test of ISO 4387 (using smog conventional analysis device to total shot thing with not containing the mensuration of the dry shot thing of nicotine).
Suitable polyethers is polyethylene glycol.Preferably, the mean molecule quantity of polyethylene glycol is roughly 200 to 3600, preferably, is roughly 400 to 1600.
During smoking, optionally get rid of the effect of phenol to strengthen filter tip further, filtering material can comprise triacetin.Comprise triacetin also to contribute to improving filter-tip rigidity, thus reduce filter tip possibility of rupturing during process smoking product and during smoking.In some embodiments comprising triacetin, the weight content of the triacetin in the filtering material of filter segments is preferably roughly 1% to 15%, is more preferably roughly 5% to 10%, is most preferably roughly 3% to 5%.
Preferably, when measuring according to the arbitrary experiment in experiment below, being roughly less than in 40 days, preferably being roughly less than in 30 days, the filtering material according to two aspects of the present invention at least roughly will degrade 30%; More preferably, 40% is at least roughly degraded; Further preferably, 50% is at least roughly degraded.
ISO 14855-2005, experiment 1: the aerobic biodegradation under controlled composting (composting) condition.
ISO 14851-2004, experiment 2: in aqueous medium, aerobic respiration biological degradability measures.
