Abstract

A filling material for cigarette filters showing e.g. under certain test conditions an absorption speed of acrolein 50% higher than that of cellulose acetate fillers is produced by extruding linear polyamide solns. into an agitated coagulating bath contg. a solvent in which the polymer is dissolved. The ppte. is an aggregate of fibril line material which can be used unaltered or reduced to a finely divided powderlike mass.
