Abstract: A method for producing cellulose-fibre-based drinking straws and a drinking straw. The method comprises:



providing a cellulose material,
producing at least one aqueous suspension comprising the cellulose material and adding additives to the suspension,
homogenizing the aqueous suspension and pre-drying to obtain at least one water-containing non-woven web having a first side and a second side,
drying the water-containing non-woven web in a plurality of drying steps to form at least one paper web having a first side and a second side,
further processing the paper web or a plurality of paper webs to form a cellulose-fibre-based drinking straw.




At least the first side of the non-woven web is compressed with a line load of 80 kN/m to 500 kN/m before, during or after one of the drying steps and before the further processing to form a cellulose-fibre-based drinking straw.
