A cord, in particular for reinforcing tyres, containing a cellulosic multifilament yarn is disclosed, where the cellulosic multifilament yarn has a strength of at least 35 cN/tex and the individual filaments of the multifilament yarn have a linear density of at least 2.3 dtex. In use, such cords exhibit a significantly improved fatigue behaviour-i.e., a significantly higher fatigue resistance-than standard cords with an individual-filament linear density between 1 and 2 dtex.
