Method for increasing the elastic properties of a thread

Abstract

The present invention relates to a method for increasing the elastic properties of a yarn obtained by a melt spinning process comprising a step 1°) in which the yarn is subjected to relaxation at a temperature ranging from approximately 70°C to approximately 110°C. Figure 3
