Abstract: The invention relates to a cellulose-containing fibrous material for a nonwoven product, in particular in the form of a wiping cloth, cleaning cloth, sanitary product, medicinal product, or domestic cloth, wherein the fibrous material is designed as a tubular composite structure at least in part or in some regions, said structure having tubular cellulose acetate filaments. The invention additionally relates to a nonwoven product which has the fibrous material according to the invention and to a method for producing such a cellulose acetate-containing fibrous material.

Abstract: The invention relates to a method for recycling cellulose acetate-containing material, such as a filter tow starting material which consists of cellulose acetate or at least has cellulose acetate. The method has the following steps: supplying a filter tow starting material to a pelletizing press; and pelletizing the filter tow starting material in the pelletizing press in order to convert the filter toe starting material into pellets, wherein the converted pellets have a higher density than the supplied filter tow starting material, and the filter tow starting material, the pellets, and/or intermediate stages of the material are cooled at least temporarily during the pelletizing process.

Abstract: The invention relates to a filter material and/or filler material for mouthpieces for use with smoking products or HNB products, the filter material and/or filler material being based on cellulose acetate filaments, at least parts of which are in the form of hollow cellulose acetate filaments. The invention also relates to a mouthpiece for use with smoking products or HNB products, the mouthpiece comprising a filter material and/or filler material of the type according to the invention. The invention also relates to a cigarette filter comprising such a filter material and/or filler material, and to a corresponding method for manufacturing a filter material and/or filler material for mouthpieces for use with smoking products or HNB products.

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.
