The polyethylene fibers have high-density polyethylene in an interior region of the fibers and low-density polyethylene in an outer region of the fibers, and a third filter component includes web-forming fibers. An independent claim is also included for a method for producing a filter.
Description
Technical field
The present invention relates to a kind of goods that are used for tobacco industry,, comprise at least one first filter component and one second filter component especially for the filter tip of cigarette.
Background technology
The applicant's EP 1 354 522 A2 disclose a kind of cigarette filter and a kind of method that is used to make this cigarette filter, and wherein, a filter component is a kind of multicomponent fibre, and wherein, the length of this multicomponent fibre is less than filter-tip length.This multicomponent fibre comprises a foreskin of being made up of a kind of material, and this material has the fusing point of the fusing point of the core that is lower than multicomponent fibre.When making filter tip, at least a its length is formed a bar less than the multicomponent fibre of filter-tip length to be made.This ribbon then is heated to above the temperature of fusion temperature of the foreskin of multicomponent fibre.This ribbon then is cooled to below the temperature of fusion temperature of the foreskin of multicomponent fibre.The crosslinked possibility that becomes in view of the above that multicomponent fibre is mutual, this makes the mutual secure bond of multicomponent fibre become possibility.According to EP 1 354 522 A2, also regulation has other component, as other kind fiber or particle, as activated carbon granule.At this moment, be that first filter component of the form of expression is pasted on the filter component of knot at other in other words being attached on the contact point with the multicomponent fibre, make adhering to accordingly of particle or other kinds fiber become possibility.
The present invention from EP 1 354 522 A2 of its should be gamut take in the record content of the present invention.
Summary of the invention
Task of the present invention is to provide a kind of filter tip that has uniform structure and can be convenient to make.In addition, task of the present invention also is to provide a kind of filter tip corresponding, with low cost.
Above task is by a kind of goods that are used for tobacco industry, filter tip especially for cigarette is solved, this filter tip comprises at least one first filter component and one second filter component, wherein, first filter component comprises that the polyethylene fibre and second filter component comprise a kind of particle.Described particle preferably has filtration and/or distributes a kind of fragrance matter.
, determined that astoundingly polyethylene fibre also can be used as binder fibre therebetween, this polyethylene fibre near being heated to poly fusing point the time at short notice not atrophy become to drip, but combine with other filter component, obtain the filter component of stable bond.
Particle preferably includes powder and/or ball.In addition, the notion particle in category of the present invention, also comprise notion crystal grain, powder particle aggregation, pulverizing/granular or pulverous material and sphere.Particle can have the shape of asymmetric shape or symmetry.Particularly preferably be, second filter component comprises active carbon, ion exchange resin and/or aluminium oxide.The active carbon that second filter component can for example comprise sugar, be made up of brown coal and anthracite or coke, by the plant or the plant part of carbonization, the active carbon that constitutes as timber or nut skin and/or comprise silica, zeolite, hopcalite, described ion exchange resin in addition, preferably has the function group, marble, lime stone, expanded clay, the improved expanded clay in close organic matter ground and phyllosilicate and celluar concrete, silica gel and titanium oxide.
As the component of fruit granule or particle crystal grain or particulate mass and/or ball 0.3 millimeter to 0.8 millimeter diameter is arranged, then in filter tip, have stable especially associating.
If the length of polyethylene fibre, has then guaranteed good especially filtering function less than filter-tip length.The length of polyethylene fibre is preferably between 0.5 millimeter and 30 millimeters, particularly between 2 millimeters and 8 millimeters and particularly preferably between 3 millimeters and 6 millimeters.Polyethylene fibre preferably is longer than its length after heat treatment in the length before the heat treatment.
The inside that polyethylene fibre is preferably in fiber has highdensity polyethylene and has low-density polyethylene in the outside of fiber.
The filter-tip stability of made can be improved greatly by being provided with this polyethylene fibre.High density polyethylene (HDPE) (HDPE) for example can be adopted in inside at fiber.This material has about 0.94 gram per centimeter

As fruit granule shared share in filter tip be 35% (percentage by weight) to 95% (percentage by weight), to 90% (percentage by weight), a kind of particularly preferred filter tip has just been arranged in particular for 70% (percentage by weight).
Making the particle share is that 12 to 15 milligrams of/millimeter filter tips and fiber share are that 1.5 to 2.5 milligrams of/millimeter filter-tip filter tips once were fully possible.This index is applicable to have 6 millimeters to 11 mm dias, particularly has the filter tip of 7.8 mm dias (extended type).As preferred embodiment, have filter tip 90% activated carbon granule and 10% polyethylene fibre, that have 80% activated carbon granule and 20% polyethylene fibre, that have 70% activated carbon granule and 30% polyethylene fibre and that have 60% activated carbon granule and 40% polyethylene fibre and once made.This refers to percentage by weight.
Other particle or pelletoid can be mixed in the activated carbon granule and other fiber also can be mixed in the polyethylene fibre.Having the polyethylene fiber peacekeeping has only the filter tip of pelletoid also can be made.
Polyethylene fibre is viscose fibre and be interconnective and be connected with particle preferably.But wherein, not necessarily each viscose fibre also is connected with another viscose fibre.Actual conditions may be, viscose fibre be connected with a plurality of particles or particulate fraction and other viscose fibre be connected with these particles again.Notion is connected the particularly bonding that refers in the category of the present invention and adheres to.Wherein, can mainly be a kind of combination of chemistry or a kind of connection of machinery, connect or the shape connection as the power transmission shape.
Polyethylene fibre preferably is the fiber that solidifies after fusing again, and these fibers that solidify bond near the particle being in mutually when melting fiber.
A kind of preferred, be used to make above-mentioned filter-tip method and have following method step:
-first filter component is mixed with second filter component,
-by mixture shaping filter rod,
-filter rod is heated at least fusion temperature near first filter component,
-cold filtration mouth bar and
-the filter rod sizing be cut into filter tip.
Filter rod preferably, for example so is heated to the temperature more than the fusion temperature of first filter component shortly, makes the incomplete penetration of this first filter component.But, allow polyethylene fibre melt fully and allow the material that constitutes by polyethylene link to each other by heat treatment with grain fraction on the filter tip to the filter rod made, the connection that makes it to obtain each particle intergranule also is possible, and wherein, fiber is deformed or even is possible.Polyethylene fibre preferably melts or is softening at least.
By the polyethylene fibre as cementing medium, it is possible that polyethylene fibre is loaded the particle of maximum and materials similar or material.
Mix before the shaping that is preferably in filter rod and/or and carry out at the filter tip shaping.
