Abstract
The invention relates to fancy yarns, and a method of making them, in which at least two yarns, of which one forms a core and one an effect yarn, are fed to a junction point and then fed together through a heat treatment zone and assembled into the fancy yarn in a false twisting step, the core yarn having been provided with a thermoplastic binder upstream of the junction point by which the effect yarn is adhered to the core yarn.
