Definitions
- Modern cigarette filters are almost exclusively made from cellulose (2.5) acetate. Compared to the paper and cotton filters used previously, this material offers the advantage that the cable used for filter production can be manufactured in a variety of specifications, in particular with regard to the fiber cross section, and is easy to process into filters, which in turn are used for snowing cigarette makers generating machines can be used.
- the filters made from cellulose acetate also look good when smoked.
- the "hardener" triazetin (glycerol triacetate) or triethylene glycol diacetate added to the cable (not already the fibers) when producing the filter rods give the filter a high selectivity towards some health-threatening ingredients of tobacco smoke, such as phenols and N-nitrosamines.
- Di- and trisaccharides, alkali and alkaline earth salts of organic and some mineral acids e.g. magnesium chloride, magnesium sulfate, sodium chloride, sodium sulfate, etc.
- organic and some mineral acids e.g. magnesium chloride, magnesium sulfate, sodium chloride, sodium sulfate, etc.
- starch chemical or biologically partially degraded starch, starch derivatives, starch-containing products such as cereal flour, dextrins are suspended in the spinning solution, these additives are broken down by soil microorganisms in sewage treatment plants, etc.
- soil microorganisms in sewage treatment plants, etc.
- the structure of the individual fibers of the smoked cigarette filters is destroyed and the further microbiological degradation of the remaining cellulose (2,5) acetate is facilitated and accelerated.
