Abstract
The present invention relates to a bast-fibre blended fibre tow. It uses the natural characteristics of bast-fibre (ramie, flax, hemp or bluish dogbane) capable of adsorbing more harmful matters in smoke, and uses acetate fibre or polypropylene fibre to modify the above-mentioned bast fibre so as to make it obtain the characeristics of filter tip material. Its modification method is that the bast fibre and acetate fibre are blended in a certain proportion and made into the fibre tow or the acetate fibre tow solution is used to treat the bast fibre. When blending, the blending weight ratio of bast fibre and acetate fibre or polypropylene fibre is 15-85%:15-85%, and when using cellulose acetate solution to treat bast fibre, the weight ratio of bast fibre and cellulose acetate solution is 50-90%:10-50%.
Description
The present invention relates to cigarette filter material, further for utilizing natural bast fibre to chew raw material and manufacture method thereof for filter.
Current acetate silk is widely used as being the unfiltered cigarette raw material, but recently domestic and international studies show that to its filter effect, acetate fiber filter is chewed the filter effect of solid matter that produces in the pipe tobacco combustion process and gaseous substance unsatisfactory, particularly the filter efficiency of gas phase harmful substance is paid no attention to and is thought of filter to chew the resistance to suction value bigger than normal.Spell out in " different cigarette coagulums are to the comparison of people and mammal peripheral blood lymphocyte SCE and micronucleus frequency influence " literary composition that " environmental science " third phase Wang Dongmei in 1991 etc. is delivered, the kinds of cigarettes coagulum shows that to people and the mammal peripheral blood lymphocyte sisters patrilineal line of descent with only one son in each generation exchange frequency that dyes gaseous substance is the main cause that cigarette is induced the human canceration in the dark brown.Actual test shows that also for the filter rate of gaseous substance, DeGrain is chewed in the acetate fiber filter, we can say have cigarette that filter chews and no filter-tip cigarette effect much at one.Therefore in order to reduce in the flue gas harmful substance effectively to the influence of human body, particularly gaseous substance is to the harm of human body, chew the existing people of manufacture view proposes to apply additive in acetate fiber method in filter at present, as Chinese patent CN1059267A, disclosing with several nonmetallic mineral materials is that the compound filter of adsorbent is chewed, Chinese patent CN1060774A proposed with active carbon particle insert filter chew in to increase adsorption capacity.But, showing with test that after deliberation increase the technological requirement height of additive, more because of after increasing additive, the powder shot-like particle during filter is chewed increases, resistance to suction improves, and manufacturing cost obviously rises, and is difficult to implement.
The present invention is directed to the problems referred to above, proposition utilizes the natural characteristic of natural bast fibre, be to have horizontal joint line and expansion joint structure in the fiber, acinous material and plasm are arranged in the lumen, thereby has a better adsorption capability, the chemical constituent of bast fibre can be adsorbed a part of material with carcinogenesis on the other hand, therefore chews material with bast fibre as filter and can improve suction-operated to harmful substance significantly.But the bast fibre water imbibition is stronger, and hardness is relatively poor, and chewing raw material as filter has certain defective, so the present invention proposes with acetate fiber and bast fibre blending to improve the performance of bast fibre; Can put on the bast fibre with cellulose acetate solution in addition, make the characteristic of its film forming, make it to be suitable for raw material as unfiltered cigarette in bast fibre surface modification bast fibre.
For the advantage of natural characteristic that bast fibre is described, the structure of bast fibre is made simple explanation here.From the section of tool cross section as seen the full attitude of examining under a microscope bast fibre reaches, and has horizontal joint line in the bast fibre, expansion joint structure and acinous material and plasm.Wherein acinous material and plasm have the adsorption capacity to harmful substance in the gas phase, its effect is as having added additive in the acetate fiber material of routine, and bast fibre surface smoothing, the space that has width not wait in the lumen, there is part wide, has part narrow, pointed at both ends, the end is blunt round, and this structure helps being detained the harmful substance in the flue gas.In addition, great amount of hydroxy group is contained on the bast fibre surface, can with harmful substance in solid phase in the flue gas and the gas phase such as nitrosamine, hydrazine, formaldehyde, acrolein, acetaldehyde, dibenzo pyrene, nicotine, tar material chemically reactive and common composite fibre comparatively speaking, produce stronger suction-operated.
The technical scheme that the present invention proposes is divided two classes, and the first is mixed bast fibre and acetate fiber or polypropylene fibre with traditional textile industrial processes method, and combing and drafting make two kinds of fibers become a kind of compact blend fibre bundle; It two is to utilize cellulose acetate solution to handle the bast fibre tow, and above-mentioned two kinds of tow can make above-mentioned fibre bundle have the characteristic of making unfiltered cigarette again behind the artificial modification with the architectural characteristic of bast fibre to improve the filter effect to flue gas.
Of the present invention being described in detail as follows: indication bast fibre of the present invention is ramie, flax, hemp or apocynum fibre.The material that is used for modification is, the monfil of acetate fiber or polypropylene fibre or the monfil of polypropylene fibre can carry out blending with bast fibre and obtain the fibre bundle of blending, and the material that is used for solution-treated refers to cellulose acetate solution.
When making the blend fibre tow with acetate fiber or polypropylene fibre and bast fibre, the weight ratio of bast fibre and acetate fiber or polypropylene fibre is 15-85%: 15: 85%.Concrete manufacture method is: at first mixed in mixing machine with acetate fiber or polypropylene fibre the bast fibre that requires in proportion, feed carding machine combing 1-5 time again, and it is even that two kinds of fibers are fully mixed; At last the fibre strip of the integrated constant weight of the fiber after combing, shape is fed the drawing frame drafting 0-3 time again, make the monofilament bonding of two kinds of fibers tighter, thickness is more even, arranges more parallelly, and becomes the linen chemical blended fibre tow of chewing material as filter.
When utilizing cellulose acetate solution to handle bast fibre, the weight ratio of bast fibre and cellulose acetate solution is 50-90%: 10-50%.Manufacture method is as follows: at first by a certain percentage bast fibre with the carding machine combing once the back with the cellulose acetate solution dipping or spray, solution is reclaimed in evaporation then, make the surface of bast fibre form the cellulose acetate film layer, send the carding machine combing bast fibre with acetate film layer again, make the bast fibre tow disturb song, be bonded at the block film breaks of acetate fiber on bast fibre surface, each monofilament of fiber separates, this moment, the surface of bast fibre silk still kept the acetate film layer, and then recarding, drafting and obtain to have good hydrophobicity, the linen chemical blended fibre tow of intensity and hardness.
The linen chemical blended fibre tow opening, gluing, moulding, sealing is cut off and namely be can be made into unfiltered cigarette, compares with the acetate fiber filter, it is little that linen chemical blended fibre tow of the present invention has pressure drop, good permeability, smoking quality improves, and the harmful substances from flue gases especially filter effect of gas phase harmful substance is had significant improvement.
