A treatment for elastic polyurethane fibers, characterized by comprising a dispersion prepared by dispersing a higher fatty acid/magnesium salt in the colloidal form in a silicone mixture composed of a dispersion medium comprising a silicone oil and a dispersant mainly comprising a modified silicone, wherein the proportion of the salt ranges from 1 to 10 parts by weight per 100 parts by weight of the silicone oil, the ratio of the dispersion medium to the dispersant ranges from 100/0.5 to 100/4.5 (by weight), and the silicone oil has a viscosity ranging from 5 x 10-6 to 50 x 10- 6 m2/s.
Cette invention se rapporte à un traitement pour fibres élastiques de polyuréthanne qui consiste à utiliser une dispersion que l'on prépare en dispersant un acide gras supérieur/sel de magnésium sous forme colloïdale dans un mélange à base de silicone composé d'un milieu de dispersion contenant une huile de silicone et un agent dispersant comportant principalement une silicone modifiée. Dans ladite dispersion, la proportion du sel est comprise entre 1 et 10 parts en poids pour 100 parts en poids de l'huile de silicone, le rapport du milieu de dispersion à l'agent dispersant étant compris entre 100/0,5 et 100/4,5 (en poids), et l'huile de silicone possède une viscosité comprise entre 5 x 10?-6¿ et 50 x 10?-6¿ m?2¿/s.
