CORD MADE OF CELLULOSIC MULTIFILAMENT YARNS HAVING AN INCREASED LINEAR DENSITY OF INDIVIDUAL FILAMENTS

摘要

A cord, in particular for reinforcing tyres, containing a cellulosic multifilament yarn, characterized in that 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, is disclosed. In use, such cords display a significantly improved fatigue behaviour, i.e. a significantly higher fatigue resistance, than standard cords having a linear density of the individual filaments in the range from 1 to 2 dtex.
