Abstract
Process for obtaining an elastic composite yarn, in which one of the components is an elastomeric yarn, characterized in that the other or other components that are twisted together with the elastomeric component are imparted a torsion of 200 to 800 turns per meter, whereby the unstretched non-elastomer component or components have a total weight that is 0.7 to 3.0 times the weight of the elastomeric component without stretching, and that the elastomeric component in the composite yarn has a weight that is 7 at 20% of the weight of the composite yarn.
