Description
Technical field
The present invention relates to cigarette producing field, relate in particular to a kind of single dawn tow of the burnt cigarette filter rod of falling of X-type cross section mixing and its preparation method and application that has.
Background technology
Along with the growing interest of consumer to smoking and health problem, the work of tobacco business reducing tar and reducing harm has obtained certain progress, tar content in cigarette is down to current 11mg from the 17mg of 02 year, by 2015, State Tobacco Monopoly Bureau requires cigarette packs mark tar content to be no more than 10mg, harmfulness index must not exceed 9, and this has proposed new challenge to tobacco business again.The low-coke tar cigarette of home sale is substantially all coordinated with cigarette punching and is fallen Jiao by the special-shaped filter stick such as composite filter, paper filter stick at present.
Chinese invention patent (application number: 200710066437.5 applyings date: 2007-12-11) discloses a kind of novel tow mixing and matching filter tip rod, carry out respectively shredding by one or more tow in acetate fiber, polypropylene fibre, polyester fiber and the regenerated fiber of different tow types, and carry out in proportion blending, moulding and make and form along axle center to circumference that different densities distributes, unlike material distributes, make every fiber there is the cigarette filter tip rod to the different strainabilities of flue gas composition.When the present invention filters flue gas, different densities distributes, the combination of the tow of unlike material can improve the filter efficiency to flue gas greatly, be conducive to the reservation of fragrance ingredient, give full play to the maximum effect of every fiber, also can be according to Cigarette design and application needs, accurate control and the selective control of flexible modulation to flue gas composition.But this patent is after spinning, to carry out shredding to carry out blending again, 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 is synchronizeed and entered forming machine with the unordered mixing of paper mouth rod paper using, 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 fibre, 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 has changed flue gas stream simultaneously, the absorption of competing, the lowering harm and decreasing coking effect of raising 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 research and develop a kind of novel tow, this tow not only has good production efficiency, and filter stick formation process is simple and it falls burnt efficiency and suction quality promotes.
