Zusammenfassung:The application of film yarns prepared according to the invention takes place in the textile industry, the industrial sector and the foodstuffs industry. The aim and object of the invention are the efficient production of high-strength, not very material-intensive film yarns of low lustre, which have a suitable material composition and controlled split fibre formation. The solution according to the invention proposes that the film filaments consist of polypropylene with an addition of 5-10 % polystyrene and are added to the splitting assembly in the direction of film travel at an angle between 5 and 15 DEG to the vertical of the axis of the splitting assembly. The splitting ratio is at most 2:1 and the maximum coefficient of rotation alpha is 95 in the subsequent twisting of the yarn.
