Abstract

Process for the production of textile yarn of synthetic fibers, with permanent curling, characterized by the practice of the following process of operations: discretionally depending on the nature of the fiber to be treated, it is initially subjected to a printing bath in a diluted solution of a metal salt, zinc for example, in order to get it to swell conveniently, followed by a drying at 50ºC and a rest for 24 hours; treating the yarn at the end, it is subjected to a first torsion of 1000 v/m followed by an autoclave vaporization at 110ºC for 1/2 hour, and subsequent rest for 24 hours to fix it; it is then subjected to a second twist of another 1000 v/m in the same direction followed also by an autoclave vaporization at 115ºC for 1 hour and subsequent rest for 24 hours; followed by a third torsion of another 1000 v/m in the same direction preceded by a new vaporization in an autoclave at 120ºC for 1 1/2 hours and following rest for 24 hours, with which the thread will be fixed to a torsion of 3000 v/m achieved in three stages progressively intermediating as many progressive autoclave fixings with regard to temperature and time; finally the yarn is subjected to a total distortion.
