Triacetin 함량에 따른 담배필터의 이화학적 특성에 관한 연구 = Study on Some Physico-chemical Properties of Cigarette Filter Rods by Triacetin Content

다국어 초록 (Multilingual Abstract)

This study was carried out to investigate the influence of triacetin(TA) on some phisico-chemical properties of cigarette filter rods. To find the effect of TA on physical properties, we made six kinds of filters varying the TA levels(0%, 2%, 4%, 6%, 8%, 10%) and measured the hardness, resilience and roundness. The hardness of filter rods was increased from 83.2% to 94.6% with increasing the TA level hut the roundness was not affected by TA levels. After manufacturing the cigarette with the filters, we have analysed the delivery amount of phenol and TA with the content of TA. The amount of phenol was decreased from 20.6$\mu\textrm{g}$/cig. to 12.0 $\mu\textrm{g}$/cig. with increasing the TA level of the filters. The decreasing of phenol amount was thought to be caused by solution effect. Also the TA delivery of TPM was increased from 0% to 5% of TPM with increasing the amount of TA. We have found the interesting phenomena that ventilation rate was also decreasing up to 6oye with increasing TA. It seemed to be due to the encapsulated pressure drop and the reduction of the plugwrap porosity which also caused by the smear with TA on the surface of plugwrap. From this results, we could find that not only the hardness, resilience and ventilation rate but also the contents of phenol and TA in cigarette smoke was affected by the TA levels on the cigarette filter rods.
