A kind of burnt cigarette filter rod that falls of the O of having type cross section mixes single dawn tow and its preparation method and application
Technical field
The present invention relates to cigarette producing field, what particularly relate to a kind of O of having type cross section falls single dawn tow of burnt cigarette filter rod mixing and its preparation method and application.
Background technology
Along with consumer is to the growing interest of smoking and health problem, the work of tobacco business reducing tar and reducing harm achieves certain progress, tar content in cigarette is down to current 11mg from the 17mg of 02 year, by 2015, State Tobacco Monopoly Bureau requires that cigarette packs mark tar content is no more than 10mg, harmfulness index must not more than 9, and this proposes new challenge to tobacco business again.The low-coke tar cigarette of current home sale all carries out falling Jiao with cigarette punching by the special-shaped filter stick cooperation such as composite filter, paper filter stick substantially.
Chinese invention patent (application number: 200710066437.5 applyings date: 2007-12-11) discloses a kind of novel tow mixing and matching filter tip rod, shredding is carried out respectively by one or more tow in the acetate fiber of different tow type, polypropylene fibre, polyester fiber and regenerated fiber, and carry out blending in proportion, shapingly obtained form different densities distribution, unlike material distribution along axle center to circumference, make every root fiber have cigarette filter tip rod to flue gas composition difference strainability.When the present invention filters flue gas, the tow of different densities distribution, unlike material combines the filter efficiency that can greatly improve flue gas, be conducive to the reservation of fragrance ingredient, give full play to the maximum effect of every root fiber, also can according to Cigarette design and application needs, flexible modulation is to the accurate control of flue gas composition and selective control.But this patent carries out shredding to carry out blending again after spinning, and the difficulty of its actual production is very large, and production cost is high, does not reach the blending effect of expection.
Chinese invention patent (application number: 201210012187.8 applyings date: 2012-01-16) discloses cigarette filter rod and the methods for making and using same thereof of a kind of tow and the disposable unordered mixed-forming of paper, diacetate fiber fiber and the unordered mixed synchronization of paper mouth rod paper using are entered forming machine, and disposable mixed-forming is prepared into a kind of brand-new cigarette filter rod.In this filter stick, existing diacetate fiber fiber has again papery wood pulp cellulose, and flue gas synchronously by two kinds of fibers of different nature, takes full advantage of the different absorption properties of the two; The disorder distribution of two kinds of fibers changes flue gas stream, absorption of competing simultaneously, improves the lowering harm and decreasing coking effect of filter stick.
But the complex manufacturing of above-mentioned special-shaped filter stick, cost is high, production efficiency is low, cigarette smoking quality is also difficult to allow consumer accept, therefore a kind of novel tow is researched and developed, this tow not only has good production efficiency, and filter stick formation process is simple and it falls burnt efficiency and suction quality promotes.
Summary of the invention
In order to solve above-mentioned technical problem, the burnt cigarette filter rod that falls that first object of the present invention is to provide a kind of O of having type cross section mixes single dawn tow.This mixing list dawn tow can be carried out the production of filter stick by common filter-stick forming device, and effectively can reduce coke tar in cigarette.Second object of the present invention is to provide the preparation method of above-mentioned mixing list dawn tow.3rd object of the present invention is to provide the application of above-mentioned mixing list dawn tow.
In order to realize first above-mentioned object, present invention employs following technical scheme:
A kind of burnt cigarette filter rod that falls of the O of having type cross section mixes single dawn tow, the monofilament of described mixing list dawn tow 3 kinds of different monofilament linear densities that spinning obtains after the spinneret orifice of 3 kinds of different pore sizes through same spinneret sprays silk is formed, and the spinneret orifice of 3 kinds of different pore sizes requires to be uniformly distributed at same spinneret by weight ratio; Described monofilament linear density scope is 1.0 ~ 3.5dtex, and the monofilament linear density coefficient of variation is 0.10 ~ 0.50, and individual filament cross section shape is O type, and the material of monofilament is acetate fiber, and the weight ratio of 3 kinds of monofilament is 1 ~ 3:1 ~ 3:1 ~ 3; Fracture strength >=the 18.0N/Ktex of described mixing list dawn tow, moisture content is (6.0 ± 1.6) %, and oil content is (0.70 ~ 1.50) %, residual acetone content≤0.30%, and content of titanium dioxide is (0.40 ± 0.20) %.
As preferably, described monofilament linear density scope is 2.0 ~ 3.5dtex, and the weight ratio of the monofilament linear density coefficient of variation 0.10 ~ 0.30,3 kinds of monofilament is 1 ~ 2:1 ~ 2:1 ~ 2.
As preferably, described monofilament linear density scope is 2.0 ~ 3.0dtex, and the weight ratio of the monofilament linear density coefficient of variation 0.10 ~ 0.20,3 kinds of monofilament is 1 ~ 2:1 ~ 2:1 ~ 2.
As preferably, the fracture strength >=20.0N/Ktex of described mixing list dawn tow; Moisture content is (6.0 ± 1.5) %; Agent content is (0.80 ~ 1.30) %; Residual acetone content≤0.28%; Content of titanium dioxide is (0.40 ± 0.15) %.
As preferably, the monofilament of 3 kinds of described different monofilament linear densities is respectively 2.0 ~ 2.4 dtex, 2.6 ~ 2.8 dtex, 2.9 ~ 3.5dtex.
As most preferably, the monofilament of 3 kinds of described different monofilament linear densities is respectively 2.3dtex, 2.7dtex, 3.0dtex.
As most preferably, the weight ratio of 3 kinds of described monofilament is 1:1:1.
In order to realize second above-mentioned object, present invention employs following technical scheme:
A kind of method preparing described mixing list dawn tow, the method comprises the following steps: that vinegar sheet acetone being carried out dissolving forms slurries, slurries are filtered, enter spinning equipment, slurries are through the spinneret orifice of different pore size, form the silk of different monofilament linear density, the silk that the proportioning of carrying out different pore size hole count according to designing requirement is spun, go out the single dawn tow finished product of a kind of mixing through crimped tow, drying, pendulum wire, packing final production.
In order to realize the 3rd above-mentioned object, present invention employs following technical scheme:
Burnt cigarette filter rod falls in one, and this filter stick is shaping obtained through common filter-stick forming device by described mixing list dawn tow.
Burnt cigarette falls in one, the cigarette filter rod described in filter stick employing of this cigarette.
The present invention is owing to have employed above-mentioned technical scheme, this mixing list dawn tow can be carried out the production of filter stick by common filter-stick forming device, described filter stick not only has and identical falls burnt efficiency, compared with the special-shaped filter sticks such as composite filter, also there is more easily processing, efficiency is high, fall the feature that burnt efficiency is more stable.
