Abstract
The invention discloses a cigarette filter tow and a preparation method thereof. The cigarette filter tow comprises the main component of a blending modified polylactic acid material. The blending modified polylactic acid material comprises the following components in parts by weight: 100 parts of temperature resistant lactic acid polyester mixture, 0.5-1.2 parts of polyethylene glycol, 0.5-1.2 parts of polyhydroxyalkanoate, 2-2.75 parts of mixture of thermal stabilizer and antioxidant additive, 0.3-0.7 part of adsorbent and 0.3-0.7 part of titanium dioxide. The invention has the advantages that the thermal resistance and thermal stability of the polylactic acid material are improved because of the temperature resistant additive or a polylactic acid nucleater and the mixture of the thermal stabilizer and the antioxidant additive; in addition, the tension thermoforming is carried out on a thermal steam box at 97-103 DEG C through a stretched fiber tow, the fiber tow is sprayed by using cold water before entering a crimping machine to avoid nodositas and stiffness of the fiber tow; the curled tow is sprayed by using a spraying device which is placed behind a crimping knife, and an anti-toxic smoke solution is placed in the spraying device, therefore, the affinity and the adsorbability of the cigarette filter tow on a toxic substance can be improved.
Description
Technical field
The present invention relates to a kind of tow, relate in particular to a kind of cigarette-filter tow and preparation method thereof.
Background technology
Cigarette filter is the important component part of cigarette, can improve the cigarette mouthfeel and reduce in the flue gas harmful substance to the injury of human body.The material for preparing cigarette filter in the market mainly contains acetate fiber and polypropylene fibre; The cigarette filter combination property that acetate fiber is produced is superior; Be mainly used in medium-to-high grade cigarette, but it is a raw material with the timber of high-quality, production process is complicated and be accompanied by many pollution problems.China's Forest Resources is limited, and acetate fiber can not be self-supporting, needs a large amount of imports every year; But along with the enhancing day by day of serious day by day and people's environmental consciousness of deforestation, a lot of countries have limited deforestation, cause being becoming tight supply day of the interior acetate fiber of global range; Hold at high price, this has determined cellulose acetate fibre in low and middle-grade cigarette, not use in a large number, and acetate fiber itself can be degraded in addition; But after esterification; Biodegradability descends to some extent, generally needs 15 years ability biodegradable fully, no longer is proper degradable material; The polypropylene fibre source is abundant, and production process is simple, and price is lower, but because the design feature of itself, poor-performings such as filter tip outward appearance, hardness, obstruct and the absorption of its production can only be used for low and middle-grade cigarette.
In recent years, biodegradated polymer materals such as PLA, polyhydroxyalkanoate and poly butylene succinate had had development, particularly PLA fast; Biodegradation can take place in natural conditions or under people's concrete conditions in the establishment of a specific crime in PLA, finally generates carbon dioxide and water, does not stay any pollutant, is genuine green material; The PLA source is abundant; Its raw material sources are in native starches such as corn, Ipomoea batatas, and its resource can be regenerated, and PLA has good processing properties; Can adopt the various processing methods of general thermoplastic to process; Comprise melt spinning, PLA has filtration to some harmful substance in the flue gas in addition, possesses as the good condition of the novel cigarette that replaces acetate fiber and polypropylene fibre with filter filament; But there is following problem in the filter filament of unmodified poly-lactic acid material preparation: the heatproof typing is limited in one's ability; The filter tip of preparation is installed in cigarette Zhi Shanghou; When cigarette props up when being pumped near filter tip; Filter tip can be because flue-gas temperature too high and moment drop-head, and fume leakage reduces filter-tip adsorptivity; Present in addition cigarette-filter tow is general to adopt traditional process to prepare; Have following problem: first filter filament moisture pick-up properties is general, and the rate of getting damp has a strong impact on filter-tip adsorptivity and compatibility 0.4% ~ 0.6%; Cause the alkoxy free group, alkyl diradical, carbon monoxide, tar and the content of beary metal that contain in the flue gas can't satisfy the New Set of " Framework Convention on Tobacco Control "; Present tow preparing makes filter tip and is installed in cigarette Zhi Shanghou, and general tar content is 15mg, and nicotine content is 1.5mg; Alkoxy free group and alkyl diradical content content are 14mg, and carbon monoxide content is 14mg; Its two the preparation filter filament process in; When in crimping machine, curling, because the crimping wheel high-speed rotation, friction place of tow and curling wheel face, doctor blade actinal surface can produce high heat; And cause tow to produce stiffization of nodositas; At filter tip hardness >=90% that after filter-stick forming device shredding gluing, prepares, Zhou Yuandu >=0.3mm becomes defective work.
Summary of the invention
It is raw material that a technical problem to be solved by this invention provides a kind of poly-lactic acid material with blending and modifying; Can improve the tow heat distortion temperature; Can not cause when cigarette smoking is near the filter tip of this tow preparation, filter tip can produce the cigarette-filter tow of moment drop-head because flue-gas temperature is too high;
Another technical problem that the present invention will solve provide a kind of through improvement tow moisture pick-up properties with improve tow get damp rate, adsorptivity and compatibility; Reduce the harmful substances such as tar, carbon monoxide, alkyl diradical, alkoxy free group and heavy metal element that contain in the flue gas; Satisfy the New Set of " Framework Convention on Tobacco Control ", can avoid in curly course, producing the cigarette-filter tow preparation method of stiffization of nodositas in addition.
