Abstract
A tobacco smoke filter or filter element comprising a cylindrical plug of a substantially homogeneous filtering material of circumference between 14.0 and 23.2 mm, wherein the substantially homogeneous filtering material comprises a plurality of randomly oriented staple fibres.
Description
The present invention relates to be used for tobacco product, such as cigarette, filter tip that particularly thin cigarette is used and filter components.
The circumference of conventional cigarette is that about 24.5-" carefully " cigarettes (about circumference 21-23.2mm) and " ultra-fine " cigarette (about circumference 16-18mm) also are known.The tobacco of manufacturing even narrower circumference is also cooked and obtains, and for example scope is 14-16mm, though this can not buy usually from the market.In this article, term " carefully " should be understood to include all have 14.0 and 23.2mm between the cigarette and/or the cigarette filter of circumference.
When the output of the selected compounds in the smoke from cigarette compared that most compounds is reduced largely pari passu in the smog, selective filter (for example tar) had just taken place.Phenolic compound-for example phenol, cresols, catechol and resorcinol-be the known component of smoke from cigarette.They are that toxic compounds-especially, phenol and catechol are included in what is called " Hoffmann " inventory of the toxic compounds of finding in the smoke from cigarette.Potential selectivity reduces the amount of these compounds that send the smoker to makes us desireing.
The general filtering material that is used in the cigarette filter is that it is collected at bar-shaped form and forms filter tip or filter components together with the continuous tow of the monofilament shape cellulose acetate of glyceryl triacetate plasticising.In such continuous tow (in filter tip that is formed by it and filter components), the monofilament in the cellulose acetate tow is mainly according to vertical arrangement.What know is that cellulose acetate has the selective filter effect to phenolic compound.Than standard filter, the filter tip that is used for " carefully " cigarette has comprised the cellulose acetate filtration material of reduced volume naturally; Owing to the material that the smog that acts on analog quantity can be used is less, any selective filter effect all can reduce.Therefore make us desirably, thin filter tip be provided, its potentially selectivity reduce the amount of the phenolic compound that sends the cigarettes fines smoker to.
The specification of filter filament with filament number (denier per filament, dpf), total fiber number and fiber cross section shape represent.Filament number is defined as the weight in grams number of 9000 meters one filament; Total fiber number is defined as the quantity that dpf multiply by monofilament in the tow thus simply.Therefore, for example, 5Y30,000 tow has been described a kind of material, and the dpf of its monofilament is per 9000 meters of 5g, is shaped as Y, includes 6,000 monofilament, and total fiber number is the per 9000 meters length of 30,000 grams.In order to make standard cellulose acetate (" monoacetate ") cigarette filter (that is, thin monoacetate filter) with low circumference, must use the cellulose acetate tow of low total fiber number, the quantity of material of slender type product is conditional because can pack into.What know is that industrial, low total fiber number tow hangs down the total fiber number tow simultaneously and more is difficult to obtain on market than higher total fiber number tow more expensive (per unit weight).Therefore make us desirably, a kind of thin filter tip is provided, than the thin or ultra-fine monoacetate filter of routine, it can be made by wider total fiber number cellulose acetate tow.
According to the present invention, tobacco product smoke filter or filter components are provided, its circumference that comprises homogeneous basically 14.0 and 23.2mm between (for example, 16 and 23.2mm between) the cylindrical plug (plug) of filtering material, wherein the filtering material of homogeneous comprises the cut staple (staple fibre) of many arbitrary orientations basically.
At this, term " filtering material of homogeneous basically " refers to the filtering material that has consistent basically physical characteristic on any cross section running through.
At this, term " cut staple " refers to independent, the discrete fiber with specific length.Cut staple can be an arbitrary orientation relative to each other.Basically the filtering material of homogeneous comprises the cut staple of many arbitrary orientations, and wherein the cut staple of a part of arbitrary orientation generally laterally extends by the longitudinal axis of cylindrical plug.Basically the filtering material of homogeneous can comprise the cut staple of many arbitrary orientations, the described cut staple of at least 10% (for example, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90%) weight laterally extends by the longitudinal axis of cylindrical plug basically.
It is arbitrary orientation at (in filter or filter element) on the three-dimensional that the cut staple of term arbitrary orientation refers to cut staple.Herein, the cut staple of term arbitrary orientation is not prepared for (and not being) and refers to continuous cellulose acetate tow, and its single thread (strand) mainly is vertical arrangement (being formed by this tow as described below though wish cut staple).Herein, the cut staple of term arbitrary orientation, do not plan to be used for (and not being) refer to the net or the sheet of filtering material, its formation (by for example slurry and/or fiber) and go up as a whole then or basically on the whole net or sheet be shaped to bar-shaped (for example, by twine (wrapping)).The cut staple of term arbitrary orientation does not refer to and is rolled into bar-shaped two-dimentional paper shape goods.Herein, the cut staple of term arbitrary orientation, do not plan to be used for (and not being) refer to the net or the sheet of filtering material, its formation (by for example slurry and/or fiber) and shred then and then moulding become bar-shaped.Sheet or net can have the arbitrary orientation of two dimension, and still (even when be shredded) through handling (such as embossing), when drawing-off from the filter maker by the time they still keep some integrity degrees.Therefore, will mainly arrange by filter tip or the fiber in the filter components that sheet or net (even sheet or net of chopping) are made, and not be the cut staple of arbitrary orientation (on the three-dimensional) therefore along the longitudinal axis of filter tip or filter components.
The cut staple of many arbitrary orientations can form porous matrix, and it provides, and passage mazy-as cigarette filter the time, this will be as the passage of smog.The applicant finds, filter tip of the present invention or filter components performance can be equivalent to existing product (" monoacetate " product for example, its continuous tow by the machine-direction oriented monofilament of the cellulose acetate of glyceryl triacetate plasticising is collected at and forms bar-shaped together and make), but the applicant finds, when using, need to reduce the use of the filtering material (for example cellulose acetate) of 20-30% with the form of the cut staple of arbitrary orientation.Except reducing the use of each filter-tip filtering material, than conventional superfine product, it also has other beneficial effect, promptly can use the cellulose acetate tow of high many total fiber numbers.Therefore, the weight that obtains except the invention by the applicant reduces the cost benefit of bringing (because of the filtering material that needs still less), the unit price of its employed tow itself also can be more cheap, (expensive and be difficult to obtain) low total fiber number tow because no longer need to use.
The applicant is surprised to find that, than the monoacetate filter or the filter element (it does not comprise the cut staple of arbitrary orientation) of for example standard, tobacco product smoke filter of the present invention or filter components can provide enhancing from tobacco product smog (in cigarettes fines) remove the ability filter tip filter tip of phenols.When considering more the filtering material of low weight (cellulose acetate), the accident that reaches phenolic compound by filter tip of the present invention and filter components reduces even is even more important.The applicant also is surprised to find that, than the monoacetate filter or the filter element of for example standard, tobacco product smoke filter of the present invention or filter components can easier and degradeds more promptly under environmental condition for example.
Cut staple can be made by filamentary material.As known in the art, cut staple can curl.Cut staple can be, for example, and cellulose acetate or polypropylene fibre.Cut staple can be by fibre bundle, and for example cellulose acetate tow, polypropylene tows are made (or formation).Cut staple can be, for example, and natural and/or synthetic fibers, the fiber that forms by natural plant material or the like.Cut staple can be cellulose paste fiber (for example by hammer-mill Fibrotic those).Cut staple can be to cut off herbaceous plant (for example cutting off the tobacco leaf), is perhaps obtained by the tobacco sheet (reconstituted tobacco sheet) of recombinating.Cut staple can be introduced fragrance and/or filtering property to final products.Cut staple can have substantially the same length (Yi Zhi length basically).Cut staple can have various length.Cut staple can have, for example between 4mm and the 20mm, and for example between 5mm and the 19mm, for example between 6mm and the 18mm, the length between 7mm and the 16mm for example.Cut staple can be by fibre bundle, and for example cellulose acetate tow is made or formed, and the total fiber number of described tow is 14,000g to 55,000g is per 9,000m length, for example from 20,000g to 50,000g per 9,000m length, for example from 23,000g to 45,000g is per 9, and 000m length is for example from 25,000g to 40,000g is per 9,000m length.
Basically the filtering material of homogeneous can randomly comprise other materials, for example liquid additive (such as flavouring agent, for example menthol solutions).The filtering material of homogeneous basically that contains the cut staple of many arbitrary orientations can be formed by many undercuts protruding end, can randomly comprise other materials, for example plasticizer, adhesive material or other additives.Cut staple can on a plurality of contact points, be bonded to each other the effect of plasticizer (for example, because).
