Abstract

L'invention concerne une fibre élastique en polyuréthane, et un procédé de production de ladite fibre. Le procédé se caractérise en ce qu'un polyol de poids moléculaire élevé et un diisocyanate en quantité excessive sont mélangés dans un état de vitesse de cisaillement indiqué et prépolymérisés pour produire un prépolymère. Ce prépolymère est mis en réaction avec un allongeur de chaîne et le terminateur afin de produire un polymère. Un additif est ajouté au polymère et le polymère final est filé. Ce procédé de production de la fibre élastique en polyuréthane améliore la stabilité du polymère, présente une excellente filabilité, et diminue remarquablement la survenue de fils ondulés. La fibre élastique en polyuréthane de l'invention présente une excellente résistance à la chaleur, un thermodurcissement efficient et une force de cohérence entre les monofilaments.
