Abstract:

An experiment was designed to continuously measure the change of temperature inside the filter tip with a thermocouple in the course of simulating someone smoking the cigarette. The temperature variation curves inside the silk filter (SF) and cellulose diacetate filter (CDF) tips was tested. The results indicated that the change of temperature inside SF is much smaller than that inside CDF in the course of simulating someone smoking the cigarette. According to our analysis, when compared with cellulose diacetate, silk has smaller diameter, and on its surface exist more special functional groups and reactive groups, making it beneficial for adsorption of cigarette smoke compounds whose molecules transfer more heat from the smoke flow to the silk. Thus, the temperature rise inside SF tip is lessened.
