Description
Technical field
The present invention relates to cigarette producing field, what particularly relate to a kind of X of having type cross section falls burnt single dawn tow of cigarette filter rod mixing and its preparation method and application.
Background technology
Along with human consumer is to the growing interest of smoking and health problem, the work of tobacco industry 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, hazardness index must not more than 9, and tobacco industry is proposed again new challenge by this. The low-coke tar cigarette of current home sale all carries out falling Jiao with cigarette punching by the abnormal shape filter rod 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 cellulose acetate of different tow type, polypropylene fibre, trevira and regenerated fibre, and carry out blending in proportion, shaping obtained form different densities distribution, unlike material distribution along axle center to circumference, make every root fiber have the cigarette filter tip rod to flue gas composition difference strainability. When the present invention filters flue gas, the tow combination of different densities distribution, unlike material can improve the filtration efficiency to flue gas greatly, 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 is to the accurate control of flue gas composition and selective control. But this patent carries out shredding after spinning to carry out blending again, and the difficulty of its actual production is very big, production cost height, does not reach the blending effect of expection.
Chinese invention patent (application number: 201210012187.8 applyings date: 2012-01-16) discloses a kind of cigarette filter rod and the Synthesis and applications method thereof of tow and the disposable unordered mixing moulding of paper, diacetate fiber fiber and the paper mouth rod unordered mixed synchronization of paper using are entered forming machine, and disposable mixing moulding is prepared into a kind of brand-new cigarette filter rod. In this filter rod, 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 chaotic distribution of two kinds of fibers changes flue gas stream, absorption of competing simultaneously, it is to increase the lowering harm and decreasing coking effect of filter rod.
But the complex manufacturing of above-mentioned special-shaped filter rod, cost height, production efficiency is low, cigarette smoking quality is also difficult to allow human 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 X of having type cross section mixes single dawn tow.
