Description
Technical field
The present invention relates to cigarette producing field, more particularly to a kind of tar reducing cigarette filter stick with O type cross section are single with mixing
Denier tow and its preparation method and application.
Background technology
As consumer achieves certain to smoking and the growing interest of health problem, tobacco business work of reducing tar and reducing harm
Progressive, tar content in cigarette was down to current 11mg from the 17mg of 02 year, and by 2015, State Tobacco Monopoly Bureau required cigarette packs mark
Tar content is no more than 10mg, endangers sex index and must not exceed 9, and this proposes new challenge to tobacco business again.State is domestic at present
The low-coke tar cigarette sold, which is substantially all to coordinate to punch with cigarette by special-shaped filter sticks such as composite filter, paper filter sticks, carries out tar reduction.
Chinese invention patent (application number：200710066437.5 the applying date：2007-12-11) disclose a kind of new silk
Beam mixing and matching filter tip rod, by one in the acetate fiber of different tow types, polypropylene fibre, polyester fiber and regenerated fiber
Kind or more than one tow carry out shredding respectively, and carry out blending in proportion, shaping is made that to form difference along axle center to circumference close
Degree distribution, unlike material are distributed, and every fiber is had the cigarette filter tip rod to flue gas composition difference strainability.The present invention
When filtering flue gas, different densities distribution, the tow combination of unlike material are greatly improved the filter efficiency to flue gas, are advantageous to perfume (or spice)
The reservation of taste composition, the maximum effect of every fiber is given full play to, can also be according to Cigarette design and using needs, flexible modulation pair
The accurate control of flue gas composition and selective control.But the patent is to carry out shredding after spinning to carry out blending again, its reality
The difficulty of production is very big, and production cost is high, does not reach expected blending effect.
Chinese invention patent (application number：201210012187.8 the applying date：2012-01-16) disclose a kind of tow with
The cigarette filter rod and its methods for making and using same of the disposable unordered mixed-forming of paper, by diacetate fiber fiber and paper mouth rod paper without
Sequence mixed synchronization enters forming machine, and disposable mixed-forming is prepared into a kind of brand-new cigarette filter rod.Existing vinegar fibril in the filter stick
Bundle fiber has papery wood pulp cellulose again, and flue gas is synchronous by two kinds of fibers of different nature, takes full advantage of the different suctions of the two
Attached performance；The disorder distribution of two kinds of fibers changes flue gas stream simultaneously, produces competitive Adsorption, improves the lowering harm and decreasing coking effect of filter stick
Fruit.
But the complex manufacturing of above-mentioned special-shaped filter stick, cost is high, and production efficiency is low, and cigarette smoking quality is also difficult to
Allow consumer to receive, therefore research and develop a kind of novel tow, the tow not only has good production efficiency, filter stick formation process work
Skill is simple and its tar reduction efficiency and suction quality are lifted.
The content of the invention
In order to solve above-mentioned technical problem, of the invention first purpose is to provide a kind of tar reduction for having O type cross section and rolled up
