Abstract
The invention relates to the production of yarns with individual filaments broken in a purely random sequence. This object is achieved by initially interlacing the uniform filament yarns either during spinning and before winding or between the winding bobbin and the drawing zone and subsequently subjecting parts of the outer layers of the interlaced filament strand to brief heat treatment on a contact heater before stretching.
