Abstract
Process for the manufacture of elastic yarns, essentially characterized by the fact of subjecting a thermoplastic monofilament that is continuously moved to a tensioning process, within which process is applied, first, a thermal lock by which it is heated to the fixing temperature, and then a twisting phase, after which the monofilament is stretched, fixed by heating under pressure and subjected to a torsion in the opposite direction and to a lesser degree than previously applied, so that the monofilament remains practically unchanged. torsion but with ability to extend substantially with respect to its length in relaxed state.
