Abstract
The invention discloses a concentric filter core material and a method thereof. The method comprises the following steps that: fibers containing hydroxyl group or amino group undergo scutching, carding, drawing and spinning processes to be made into a single yarn, and the single yarn is made into piled yarn by using a rotor spinning process at a twist of between 300 and 500 twists per meter, and thus the required core material is obtained. After acetate fibers are released, the core material is drawn to a molding machine by adopting a drawing and positioning device, added to the center part of a filter by a filter molding device and processed to obtain a concentric filter bar. The concentric filter core material and the method thereof have the advantages of no requirement of adding molding paper, single molding, convenient use and low cost. As the concentric filter core material has stronger chemical absorption function to polarity compositions in smoke gas of cigarette, the travel path of aerosol particles is lengthened, the collision among the particles and the interception probability of the core material to the particles are increased, so that the aerosol particles are more easily deposited on the surface of the core material, thereby improving the filtering efficiency of the center position of the filter.
Description
Technical field
The invention belongs to the cigarette material technical field, relate to cigarette filter, particularly relate to a kind of core that is used for the concentric filter tip.The invention still further relates to the preparation method of this core simultaneously.
Background technology
Cigarette filter has important effect as the filtration system of cigarette smoke in lifting smoking property of cigarette quality and security.Along with the contradiction of smoking and health problem becomes increasingly conspicuous, countries in the world are to the exploitation growing interest of novel filter tip and material, and existing cigarette filter mainly contains binary composite filter tip, ternary composite filter tip, hollow filter tip and coaxial core filter tip etc.
Wherein, the coaxial core filter tip is meant at the shaft core position of common filter tip and inserts the formed filter tip of special filter core vertically.Has high efficiency of filtration with respect to other composite filter tip.But the employed core of existing coaxial core filter tip is acetate fiber.Common acetate fiber does not possess chemism because its hydroxyl is esterified, mainly is to realize by the pressure differential that forms between the inside and outside rod to the filtration of cigarette smoke.Chinese patent " a kind of cigaratte filter and preparation method thereof " (publication number: CN1792288A) for example, this technology adopts the acetate fiber center bar, in manufacture process, need independent moulding, compound with carrying out behind the forming paper parcel, action principle is to promote adsorption efficiency by the pressure differential that forms between center bar and the outer rod again.Not only complex forming technology, and chemisorbed efficient is lower.
In addition, the spices line filter tip of Shi Yonging is a kind of special shape of concentric filter tip in the market, and it is to add the cotton thread that contains spices at the filter tip shaft core position, and purpose is for cigarette provides feature outer perfuming, and cigarette smoke is not had filter effect substantially.
Therefore, how to improve the chemisorbed efficient of filter tip core, improve the filter effect of concentric filter tip, just become the technical problem that needs to be resolved hurrily in the production of cigarettes field.But do not see relevant report in the prior art as yet.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of coaxial core filter tip core material is provided,, thereby improve the adsorption efficiency of concentric filter tip, improve the smoking quality of cigarette oxious component by the chemism and the physical arrangement of reinforcement core.
The present invention also aims to provide a kind of method for preparing described concentric filter tip core.
Purpose of the present invention is achieved by the following technical programs.
A kind of coaxial core filter tip core material is characterized in that: the fiber that will contain hydroxyl or amino group is made single thread, again the single thread Split Down is spun into fibre bundle, is required core.
Wherein, the preferred bamboo fibre of described fiber, fibre and soya, flaxen fiber, PVA fiber or chitin fiber.
Described fibre bundle is that the diameter of core is preferably 0.5～5mm.
A kind of method for preparing coaxial core filter tip core material may further comprise the steps:
1, the fiber that will contain oh group or amino group through blowing, comb and parallel cotton fibers prior to spinning, and thick, spinning process make single thread;
2, with the twist of single thread according to 300～500 sth. made by twisting/rice, adopt the Split Down of rotor spinning technology to make a strand yarn, be required core.
Wherein said Split Down method can be with the single thread Split Down of different size, is specially: certain two or three single thread in 60s, 40s, the 32s single thread is carried out Split Down.
Described Split Down method can also be that be specially: the single thread of certain two or more fiber in the above-mentioned optimum fiber carries out the blending Split Down with the single thread blending Split Down of different fibers.
Operation principle of the present invention: cigarette is in aspiration procedure, and the flue gas flow rate in centre position is very fast, and flow is bigger.Common acetate fiber does not possess chemism because its hydroxyl is esterified, and cellulose acetate filter only is to rely on the filtration of its physical arrangement realization to cigarette smoke, causes the filter efficiency of interlude lower.The present invention selects the fiber that contains hydroxyl, amino isopolarity group for use, after the fibre spinning, adopts different Split Down methods, and forming diameter is the fibre bundle core of 0.5～5mm.The core that makes enters the filter tip former by draw-gear, adds the filter tip shaft core position to.Because this fibre bundle core has the polar group of hydroxyl, amino, and certain absorption and filtration can be arranged the polar compound in the flue gas, thereby promote the filter efficiency of filter tip to flue gas.Simultaneously, adopt rotor spinning technology, the formed core of Split Down has the physics helical structure in preferred twist number range, is different from the mode in line arranged side by side of acetate fiber.The flue gas aerosol particle flux is when core, particle detours along low resistance to suction zone, thereby has increased the walking path of particulate, has increased interparticle collision and the core interception probability to particle, make the easier surface that is deposited on core of particulate, improved the filter efficiency of filter tip.Finally reach and promote the cigarette smoking quality, the purpose of oxious component in the reduction cigarette mainstream flue gas.
The present invention has the following advantages with respect to prior art:
1, need not add forming paper, moulding separately, easy to use, with low cost.
2, because core contains hydroxyl, amino polar functional group, the polar compound in the cigarette smoke is had stronger chemisorption, improved the filter efficiency of filter tip center.
3, the helical structure that this core had can increase the walking path of particulate, increases interparticle collision and the core interception probability to particle, makes the easier surface that is deposited on core of particulate.
