Abstract
A polypropylene tow for removing harmful matter from cigarette smoke contains adsorbent (4-8.5%) and polypropylene (91.5-96%). Said adsorbent contains zeolite molecular sieve with low Si/Al ratio of 2.5-10 and the molecualr sieve with high Si/Al ratio of 40-200. Said polypropylene tow can be made into tip filter of cigarette.
Description
The present invention provides and a kind ofly can remove the polypropylene tow that mainly contains harmful substances in the cigarette smoke effectively, specifically prepares a kind of polypropylene tow of additional extraordinary adsorbent.
For a long time, be the harmful substance in reduction or the elimination cigarette smoke, murder by poisoning as tar, nicotine etc., people have carried out many researchs, and to have taked various measures and method, its technology the simplest and that widely adopted be the filter tip that adds the preparation of a kind of acetate fiber, polypropylene fiber on cigarette, but because this method still can not be got rid of the harmful substance in the cigarette smoke effectively, therefore, constantly propose to improve the technology of cigarette filter performance again.As before filter tip, increasing adsorbents such as layer of active carbon and molecular sieve, be prepared into composite filter tip technology (CN94112700.1).Though but prior art can remove the harmful substances that mainly contains in the cigarette smoke effectively, as tar, aromatic hydrocarbons, aldehydes and NOxization thing etc., but this Technology Need is invested big with the equipment of producing composite filter tip, increase the preparation cost of filter tip, popularizing in an all-round way to use has limitation.
The object of the present invention is to provide a kind of polypropylene tow of additional adsorbent, under the condition that need not increase equipment and change technology, this tow can be made filter stick, make to remove effectively behind the cigaratte filter and mainly contain harmful substances in the cigarette smoke, as tar, aromatic hydrocarbons, aldehydes and NO
xChange thing etc., and can keep smoking port strength, improve mouthfeel, reduce pungent taste, improve cigarette quality.
The invention provides a kind of polypropylene tow that harmful substance is used in the cigarette smoke that removes, it is characterized in that: this polypropylene tow is the polypropylene fiber tow that contains adsorbent, and it forms percentage by weight is adsorbent 0.5～4.0%, polypropylene 91.5～96%; Described adsorbent is to be made of low silica-alumina ratio Si/Al=2.5～10 zeolite molecular sieves and high silica alumina ratio Si/Al=40～200 molecular sieves, two components, and percentage by weight is a low silica-alumina ratio molecular sieve 60～90%, high silica alumina ratio molecular sieve 10～40%.
The molecular screening of low silica-alumina ratio described in the present invention is with one or more of the X type of silica alumina ratio 2.5～10, Y type, modenite; Described high silica alumina ratio molecular sieve is the molecular sieve of the silica alumina ratio 40～200 that is prepared into after dealumination treatment of X type, Y type, modenite or ZSM-5 zeolite.
The polypropylene fiber tow of additional adsorbent of the present invention; its preparation method is very easy; can in the process of preparation tow, add adsorbent, specifically before polypropylene wiredrawing with adsorbent and polypropylene powder or particle mixing granulation or directly miscible, hot pressing, wire drawing, make tow.Reel off raw silk from cocoons with this tow, technology is prepared into and can removes the polypropylene fiber filter stick that harmful substance is used routinely.In the tow of additional adsorbent of the present invention, the consumption of adsorbent seldom contains 0.6～48mg in every filter stick approximately, owing to contain adsorbent in the polypropylene fiber tow of invention, this adsorbent has the high absorption property of selecting, and can remove tar, aromatic hydrocarbons, aldehydes and NO from cigarette smoke
xChange thing etc., well can keep original product invariant position of cigarette, reduces pungent taste.Below by example technology of the present invention is given to illustrate in further detail.
