Description
Technical field
The present invention relates to cigarette filter rod technical field, more particularly, relate to tobacco paper filter stick of a kind of composite bamboo fiber and preparation method thereof.
Background technology
Include particulate in cigarette smoke, be usually referred to as tar.Containing a large amount of chemical compositions in tar, having 4000 to 5000 kinds, is all the unburnt product of tobacco.Except tar, in cigarette smoke, also include other materials, as " steam " or " gas " phase, also comprise volatile result of combustion of tobacco material, as acetaldehyde and other low molecule weight item.Other phases in cigarette smoke, as " half volatile " phase, comprising many combustible substances, are equal to particulate and vapor phase.
Cigarette filter rod can filter smoke composition.The filter stick of cigarette is made up of filter core and forming paper.Filter tip is the important component part of cigarette, utilizes the sorbing material in cigarette filter and additive thereof can filter out harmful substance in cigarette main flume.At present, filter tip filter material mainly contains three types: acetate fiber, polypropylene fibre and paper.
The papery filter tip be made up of crape silk paper introduces European cigarette market in the twenties in 20th century first, even if paper filter tip has stronger removal tar and the ability of nicotine, but consumer can not accept always, until the 1950's, along with the exploitation of acetate fiber, cigarette with filter tip just starts the extensive accreditation obtaining consumer, and main cause is that paper filter tip has " taste of paper ", and consumer does not often like this point.And paper is softer, seriously polluted in the process of smoking, therefore should not directly use as filter tip.
The filter core of existing filter stick is all generally adopt acetate fiber or polypropylene fibre composition.But the filter core containing fiber due to these directly contacts with the lip of human body, has media report recently, and fiber particularly polypropylene fibre may enter human body along with the suction of cigarette, and causes damage to health.Along with consumer is for the continuous pursuit of health, the filter tip prepared via chemical substance based on acetate fiber is because non-natural feature is conflicted gradually.Paper filter tip is because of natural sex and to retain efficiency to flue gas higher, and after abandoning, than acetate fiber filter tip and polypropylene fibre filter tip, paper filter tip is more easily degraded, and again receives much concern.
Bamboo fibre is exactly a kind of cellulose fibre extracted from the bamboo of self-sow, is the fifth-largest natural fiber after cotton, fiber crops, hair, silk.Bamboo fibre have good gas permeability, moment the characteristic such as water imbibition, stronger wearability and good dyeability, have again simultaneously natural antibacterial, antibacterial, except mite, deodorization and anti-ultraviolet function.Pure natural bamboo yarn is used for garment material, summer sleeping mat, sheet, curtain, scarf etc., can produce frivolous garment material as adopted with the method for polyvinyl blending.Blending can also be carried out with cotton, hair, fiber crops, thin,tough silk and chemical fibre, for woven or knitting, produce woven fabric and the knit fabric of all size.Woven fabric can be used for making jacket, easy dress, Western-style clothes suit, shirt, sheet and towel, bath towel etc.Although there is now people to be applied in cigaratte filter by bamboo fibre, be used alone the impression that bamboo fibre is not well positioned to meet smoker, the soft or hard degree that cigarette holder is suitable can not be given, namely can not get suitable smoking experience.
Also the report of some string filter stick for cigarettes is had at present, if application number is report a kind of string filter stick for cigarettes and preparation method thereof in the patent application of 200910185294.But this patent filter stick is directly made up of rice-straw fibre, wheat straw fiber, tabacco straw fiber and soybean stalk fiber, plant straw is mainly utilized to reduce cigarette cost, filter tip after minimizing uses and acetate tow production process, to the pollution of environment, can not provide the function more meeting cigarette filter rod requirement in addition.
Prior art adopts dry-papermaking to have also been obtained exploitation as the technology preparing cigarette filter tip rod filter material, mostly adopts wood pulp cellulose to be majority fibers material, or is aided with a certain proportion of composite fibre, meldable fibre or ecological fiber to reach respective target.As Chinese patent (CN180167B) " dry process paper filter tip and preparation method thereof ", it with the addition of the hot melt core-skin fibre of 5% ~ 65% in wood pulp cellulose; For another example Chinese patent application (CN101171981A) " binary composite cigarette filter stick " material of adopting expanded dry-papermaking to prepare is as the filter core of the unitary filter tip near pipe tobacco, and this material is directly made up of pure wood pulp or 50% ~ 95% wood pulp and 5% ~ 50% composite fibre; Chinese patent application (CN101624756A) " Biodegradable non-woven cloth for cigarette filter tips and preparation method thereof " is also had to have employed wood pulp cellulose, polylactic acid fiber with high melting point, low melting point acid fiber by polylactic and water-soluble glue.Also people is had directly baccy fiber to be delivered to pressing section laying net for shaping by blower fan, shaping guipure is formed fluffy uniform fleece, again through applying glue, preheating, roll-in, solidification with shapingly make cigarette filter material paper, and in forming process, add natural medicinal herbs scrap feed material.The fiber of these dry-papermakings relate to the fiber types such as wood pulp cellulose, composite fibre, hot melt core-skin fibre, acid fiber by polylactic, although these fibers can be used for the filter material making filter tip, but make the loss of cigarette perfume more while filtering flue gas, and bring certain wooden assorted gas into, when aspirating to cigarette odor-absorbing with jealously have certain negative effect, cigarette quality can not be ensured, the more important thing is the color of these current materials and quality and natural baccy feel differ greatly, the pursuit that the person that can not cater to cigarette consumption feels natural baccy.
In recent research, also there is people to be applied to by baccy fiber in dry method paper, baccy fiber is delivered to pressing section laying net for shaping by blower fan, shaping guipure is formed fluffy uniform fleece.Again through applying glue, preheating, roll-in, solidification with shapingly make cigarette filter material paper, and in forming process, add natural medicinal herbs scrap feed material.But its technical scheme is still laid by simple baccy fiber and is formed, and use various colloid to be bonded, so it removes the poor effect of assorted gas, and the colloid used too much can bring peculiar smell to cigarette holder, in addition, the problem reducing tobacco waste can not be solved, and additionally add baccy fiber in process of production, improve the Tobacco amount of whole cigarette on the contrary.
In addition, existing tobacco productive corporation aborning, produce a lot of waste material, as waste tobacco leaf, offal, fragment, offal etc., at present mainly because fall after these waste materials are reprocessed by burnt object, alternative small part pipe tobacco in the pipe tobacco of cigarette is added to the utilization of these waste materials, but well-known, the addition of these materials in pipe tobacco is subject to very large restriction, the problem that tobacco leaf production scrap materials of enterprises is disposed and the dynamics turned waste into wealth can not be solved completely.
