Description
Technical field
The invention belongs to pipe tobacco preparing technical fields, and in particular to a kind of two-component pipe tobacco, and further relate to
Preparation method.
Background technology
Pipe tobacco be produce cigarette filter rod important materials, have elasticity it is good, nontoxic, tasteless, thermal stability is high,
Resistance to suction is small, cut-off filter significant effect, can selectively adsorb harmful components in cigarette, at the same remain again certain nicotine without
The advantages of losing cigarette taste.China is to produce pipe tobacco as raw material using cellulose acetate fibre and polypropylene fibre at present,
Consider from the synthesis performance of the filter tip of processing performance and final production, is first choice with cellulose acetate fibre, uses more
In medium-to-high grade cigarette filter tip rod.
Cellulose acetate tow is through slurrying, to acetify using high-quality timber as raw material and be processed into Cellulose diacetate flake, pass through
Dissolving, filtering, spinning, curling, the production technologies such as dry are process.The cross-sectional shape of cellulose acetate tow is generally "
Y " shapes, therefore the specific surface area of fiber is larger, has preferable absorption and crown_interception to the oxious component in cigarette smoke.But
China is that timber lacks country, needs a large amount of timber of import and wood pulp every year, and cellulose acetate tow acetifies processing in slurrying
With will produce a large amount of organic wastewaters in solution spinning process, energy consumption is high, and pollution is big, seriously constrains the hair of cellulose acetate tow
Exhibition, therefore be badly in need of developing a kind of substitute products.
Fibre beam for polypropylene cigarette is a kind of distinctive filtering material of China's cigarette industry, have whiteness it is good, it is nontoxic, be no different
Taste, smooth, soft, uniform advantage.Polypropylene fibre raw material is derived from oil, is produced by the way of melt spinning, compares acetic acid
Cellulose fibre, raw material and production cost are relatively low, and production process three wastes generate.But since polypropylene is a kind of hydrocarbon knot
The apolar substance of structure, itself is without any polar group, and tow surface is smooth, and adsorption capacity can not show a candle to acetate fiber,
Smoke filtering effect is poor, and there is stronger acid in when suction, is generally only used for Low-end Cigarettes.Also, recently as tobacco
The adjustment of industry product structure, China's cigarette class are continuously improved, and Low-end Cigarettes dosage declines year by year, and fibre beam for polypropylene cigarette will
Gradually withdraw from the market.
Acid fiber by polylactic is the lactic acid produced with the fermentation of the starch crops such as reproducible corn, beet, cereal or potato
As raw material, aggregated, spinning and a kind of manufactured polyester fiber.It not only has good biocompatibility, but also degrades
Product be carbon dioxide and water, it is free from environmental pollution, have no toxic side effect to organism, be a kind of important biomolecule matter fibrous material.It grinds
Study carefully and report that acid fiber by polylactic is similar to vinegar fibre structure, molecular surface contains abundant polar group, so polylactic acid tow pair
Polar substances have stronger affinity, can be chemically reacted with tar component and lower-molecular substance, reactant firmly stays
In fiber surface, meanwhile, tow surface has micropore and harsh feeling, in the adsorption process to flue gas, while having physics suction
Echo chemisorption double effects.It is good with the made filter stick adsorption effect of poly-lactic acid material, after filter stick tipping, absorption property, pumping
Suction inlet sense is similar to vinegar fibre, hence it is evident that is better than polypropylene fiber.
Chinese Patent Application No. be 200610131699.0 and 200710055310.3 disclose it is a kind of utilize lactic acid polymer
Polymer resin manufactures the technical information of cigarette filter filament fiber and filter stick for cigarettes.But acid fiber by polylactic adds in pipe tobacco
It is had the following problems in work technique and filter stick formation technique：
（1）Acid fiber by polylactic heatproof is relatively low, the high-speed rotating thread roller of shredding gluing machine and filter-stick forming device, rubber rollers with
And can soften under the shear actions such as pressure, friction of cutter head, to which roll banding and sticking phenomenon occur, cause improper stop
Vehicle, or rod speed is greatly reduced into；
（2）Meanwhile acid fiber by polylactic lacks and is similar to safely and effectively binder as three triacetin fat；
（3）In addition, relative to cellulose acetate and polypropylene fibre, the ratio of acid fiber by polylactic is great, therefore to meet filter stick suction
The requirements such as resistance, hardness and appearance, it is necessary to more tow are filled, to cause low, the cost that goes out stick rate of acid fiber by polylactic tow
It greatly improves.
To solve the above problems, application No. is disclose one kind in 201010102007.6 Chinese patent to pass through polylactic acid
It is high to solve preparation process under the conditions of the prior art with the method for polypropene blended melt spinning, than great, filter stick formation difficulty etc.
Disadvantage.But polylactic acid is polar polymer, and polypropylene is non-polar polymer, and thermodynamics is incompatible, and shortage can actual operation.
Application No. is a kind of polylactic acid/polypropylene cigarette of skin-core structure is disclosed in 201210196240.4 Chinese patent with compound
Tow and preparation method thereof, the polylactic acid/polypropylene composite materials pipe tobacco are to use composite spinning technology, pass through melt spinning method
The section of single fiber obtained is in skin-core structure.But since polylactic acid is completely incompatible with polypropylene, the core-skin of spinning is multiple
In spinning and drafting process core-skin stripping easily occurs for condensating fiber without having practicability.Application No. is
It is disclosed in 201210196243.8 Chinese patent a kind of by by polylactic acid tobacco tow and corresponding cellulose diacetate
The method that pipe tobacco is mixed and made into filter stick alleviates the situation of vinegar fibre pipe tobacco anxiety, simultaneously to reduce tow line density
It keeps the suction taste of cigarette without too big change, and reduces cost.But polylactic acid tow and cellulose acetate are not described in the patent
How tow is mixed, and since acid fiber by polylactic uses melt-spinning technology, and cellulose acetate fibre uses solution-polymerized SBR
Technique, therefore two kinds of fibers can not possibly realize mixing in spinning process.Meanwhile two kinds of continuous long strands are difficult in process of production
With evenly dispersed, do not have practicability.
