Abstract
The invention relates to a filter tow strip, especially twin tow from cross-linked and crimped filaments which form at least two partial strips (12a, 12b) that are interlinked by a section of reduced cross-linking density (11), the linking filaments (13) being interlooped and/or interlocked in such a manner that the linking filaments form intersections (14). The filter two strip is characterized in that the maximum cross-cutting force of the partial strips (12a, 12b) does not exceed 20 cN on a length of approximately 20 cm of the filter tow strip (10) and/or the number of the Baking filaments (13) does not exceed 200 cross-locking and/or cross-looping filaments on a length of approximately 20 cm of the filter tow strip (10) when impinged with the maximum cross-cutting force.
