Abstract


With the enhancement of people's health awareness , how to reduce the tar content of the cigarette and the mainstream smoke , to improve the safety of cigarette smoking , has become the focus of tobacco and related industries . This paper reviews the current cigarette harm reduction method and the status quo , and discussed the important role of the filter in reducing tar harm reduction . By enzyme technology and a plasma processing technology , the focus from the surface modification of the filter with a cellulose acetate , and in improving the fiber than the surface area at the same time , can further improve the filtration performance of the cellulose acetate filter , and for cigarette tar reducing harm reduction new ways . Biological enzyme technology and plasma processing technology are two kinds of environment-friendly fiber surface modification technology . The paper discusses the mechanism of these two technologies separate processing and co-processing filter with cellulose acetate . Meanwhile, using Airflow detection alkylene methyl blue coloring , SEM images , infrared spectroscopy and surface contact angle , evaluation method , testing the acetate fibers intact and processed after the fibers of the surface properties change , to a certain extent can indirectly reflect improved filter filtering performance of . Plasma on the physical impact of the fibers and surface etching of the fiber surface to produce pits and grooves , the surface of the fibrous material at the same time the introduction of oxygen-containing or nitrogen - containing group ; cellulase on the hydrolysis of cellulose , prompting the fiber surface eroded ; plasma and biological enzyme treatment can make the fiber surface roughening , the specific surface area increases , so that the surface properties of the fibers to be significantly improved . The experimental results herein show that : the cellulase and plasma technology for improving the filter with the surface properties of the cellulose acetate effect obvious; both co-processing , the plasma pretreatment for the enzyme treatment to provide a better reaction conditions synergistic effect the most obvious.
