20130171450 | CORDS MADE OF CELLULOSIC MULTIFILAMENT YARNS HAVING AN INCREASED LINEAR DENSITY OF INDIVIDUAL FILAMENTS - 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. | 07-04-2013 |
