Abstract

Abstract of the Disclosure The invention relates to a filter tow made from crimped endless cellulose acetate filaments, whereby the filaments form at least two connected fibre bundles with the same filament titre of at least 600 filaments. The filament titres differ from bundle to bundle by at least 1 dtex Furthermore a filter tow is disclosed with a crimp ratio of more than 40%, said filaments comprising at least 22 crimp turns per filament length.
