More Information
Summary:The invention relates to a high performance cigarette filter on the basis of cellulose ester fibers or filaments which can be mechanically disintegrated. The inventive high-performance cigarette filter is characterized in that a) the fiber weight (or filament weight)/draw resistance ratio S based on the filament titer is greater than approximately 0.7, the S value being calculated according to the formula S=(mA/DeltaP7.8/dpf[10 m/daPA], wherein mA refers to the fiber weight, DeltaP refers to the draw resistance and dpf represents the filament titer and for the draw resistance the value calculated for a diameter of 7.8 mm is inserted, b) the residual crimping value of the filter material does not exceed the value 1.45, c) the fiber weight amounts to maximally 10 mg/mm of the filter length, and d) the hardness of the cigarette filter is higher than approximately 90% filtrona hardness. The inventive filter is characterized by an improved disintegratability under environmental conditions vis-à-vis comparable products.
