Effect of silk fibers in lowering the content of aldehydes in the smoke mainly from lit cigarettes

To investigate the effect of silk fibers in adsorbing and filtering aldehydes in the smoke mainly from the lit cigarettes,silk fiber filter tips were prepared.Through the simulated smoking,mainstream smoke was collected,and the contents of aldehydes in mainstream smoke,and the amount of aldehydes adsorbed by silk fibers in filter tips were determined with colorimetry.Results indicate that,the larger the filling density of silk fiber filter tips,the lower the content of aldehydes in mainstream smoke of cigarettes,at the same time,the higher the amount of aldehydes adsorbed by silk fibers in filter tip.Silk fibers perform excellently in lowering the content of aldehydes in the smoke mainly from lit cigaretts.
