Abstract
Process for manufacturing core yarns, having decitex of the order of 120 to 400, inclusive, characterized in that it comprises supplying at least two continuous synthetic filamentary components in sequence to a feeding device, a heating zone, a cooling zone and a false filament element and remove said filamentary components of said sequence at a higher tension than the tension with which said components are supplied to said sequence, so that the filaments are stretched from 1.5 to 6.0 times their length in the feeding point, differentiating the filamentary components in regard to its stretchability under the stresses to penetrate the section of yarn of increasing torsion, being the ratio of the component's decitex greater stretchability to the decitex of the component of lower stretchability of the order of 1.5: 1 to 3: 1 inclusive.
