Abstract (en)
[origin: DE19730485A1] The invention relates to cellulose acetate filaments with trilobal cross section and with a degree of substitution of approximately 2.1 to 3.0. They have a filament titer of less than 3.3 dtex, a PE form factor of less than 0.320, and a PH form factor of less than 0.560. These cellulose acetate filaments have particularly advantageous absorptive qualities when used in cigarette filters.
