Abstract
The invention provides a filter rod with coaxial paper cores, comprising a filter rod and an outer ring of forming paper. The filter rod contains an inner core and an outer core which are coaxial, the diameter of the inner core is 3-6mm, an inner ring of forming paper can be also arranged around the inner core which is a paper core, the outer core is an acetate fiber core or the inner core is an acetate fiber core and the outer core is the paper core mainly prepared from wood pulp fiber as a main material; the thickness of the inner ring of forming paper is not larger than the thickness of the outer ring of the forming paper; and the color of the inner ring of forming paper is white or is the same color as the color of the outer ring of the forming paper. The filter rod of the invention has better adsorption performance, can further reduce the contents of harmful gases in smoke, such as tar, carbon monoxide, nitrogen oxides, phenols, and the like, improves the smoke taste, reduces the consumption of acetate fiber, decreases the cost and is favorable to environmental protection because the paper cores are easier to degrade.
Description
Technical field
The present invention relates to the filter stick of cigarette, refer in particular to a kind of coaxial filter stick of refill that contains inner core and outer core.
Background technology
The filter tip of cigarette is to be cut by filter stick to form, and filter stick is to be formed by filter core and forming paper structure.Common filter core is to be made by independent acetate fiber core or polypropylene fibre core, exists that adsorptivity is not high enough, the cost problem of higher.Also have the filter core of being made by refill, though absorption property is good, but moisture-proof, anti-flammability, moulding full weight and suction flavor are good inadequately.
The number of applying for a patent discloses a kind of coaxial core filter tip core material and manufacture method thereof for the specification of CN200810058692.X, be at the intrafascicular fiber that includes oh group or amino group of acetate fibres, its absorption property increases, but, oh group that increases or amino group might be decomposed into little molecule, and health is had negative effect.
The number of applying for a patent discloses a kind of cigaratte filter and preparation method thereof for the specification of CN200610010602.0, constitute by the peripheral forming paper of rod and center bar outside acetate fiber center bar and the acetate fiber, there is sorbing material on the surface of forming paper, the adsorptivity that the method improves is not brought by the acetate fiber filter core, but provide by very thin forming paper, the absorption property of filter core itself does not have raising, and the absorption property of filter stick integral body also just improves few.
Summary of the invention
Goal of the invention: overcome the defective of the not enough or unsoundness hidden danger of its common filter stick and other coaxial filter stick adsorptivities, a kind of coaxial filter stick of refill with better adsorptivity and feature of environmental protection is provided.
Technical scheme: the coaxial filter stick of refill of the present invention, contain filter core and outer ring forming paper.Filter core contains coaxial inner core and outer core, and the inner core end face is circle, polygon or irregularly shaped, the diameter of inner core end face or or external diameter of a circle be 3mm-6mm.Inner core is a refill, and outer core is the acetate fiber core; Perhaps, inner core is the acetate fiber core, and outer core is a refill.
Among the present invention, inner core is a refill, and when outer core was the acetate fiber core, the absorption property of filter stick was best.The peripheral inner ring forming paper in addition of described inner core, inner core will wrap up closelyr, and the filter stick outward appearance after the moulding is better.
The primary raw material of described refill is a wood pulp cellulose, wherein can join a kind of or several natural fibers that are mixed with in grass fiber, bamboo fibre, flaxen fiber, the cotton fiber, so that reduce cost.Can also join a kind of or several staple fibres that are mixed with in acetate fiber, polyester fiber, polyethylene fibre, polypropylene fibre, vinylon fiber, the acid fiber by polylactic in the described refill.
Can in the raw material of described refill, be mixed or be coated with multiple inorganic or organic additive,, inhale flavor to improve its adsorptivity, anti-flammability, resistance to water or to change it as medical stone, activated carbon, polysaccharide, natural plant pefume etc. on its surface.
The thickness of described inner ring forming paper is not more than the thickness of outer ring forming paper, and the color of inner ring forming paper is white or is the color of outer ring forming paper.
The inner surface of described inner ring forming paper or outer surface can also be coated with white glue with vinyl, to improve the adhesion of inner core and outer core.
The inner surface of described inner ring forming paper or outer surface can also be coated with the sorbing material of absorption poison gas, perhaps also are coated with to improve the sapid material of inhaling flavor, as medical stone, activated carbon, polysaccharide, natural plant pefume etc.
Beneficial effect: the dual structure of inner core of the present invention and outer core, filter efficiency is fabulous.Inner core or outer core material adopt the better refill material of absorption property, can further adsorb pernicious gases such as tar in the flue gas, carbon monoxide, oxynitrides and phenols, minimizing is to the harm of health of smokers, and other additives of increase can improve the flue gas mouthfeel and inhale flavor.And the easier degraded of refill helps environmental protection.Reduce more expensive acetate fiber use amount, can reduce the cost of filter stick.Simultaneously, the coaxial filter stick of twin-core, the visual effect novelty of its end is peculiar, can increase aesthetic feeling.
Description of drawings
Accompanying drawing is a cross-sectional view of the present invention.
Among the figure: 1, inner core; 2, inner ring forming paper; 3, outer core; 4, outer ring forming paper.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is done description more specifically.
Embodiment 1
Inner core 1 end face is circular refill, and the diameter of inner core 1 end face is 3mm, and outer core 3 is the acetate fiber core, and outer core 3 peripheries are enclosed with outer ring forming paper 4.The primary raw material of refill is a wood pulp cellulose, and wherein ginseng is mixed with a kind of or several natural fibers in grass fiber, bamboo fibre, flaxen fiber, the cotton fiber.Also be mixed in the raw material of refill activated carbon and natural plant pefume are to improve its adsorptivity, to change it and inhale flavor.On improved filter-stick forming device, make inner core 1 earlier, make the coaxial filter stick of refill of this material, structure and shape again.
