Abstract

L'invention concerne un procédé de fabrication de fils continus de polypropylène à surface modifiée pouvant être teints à partir de bains de teinture aqueux. L'invention est caractérisée en ce que les fils continus en PP standard du commerce sont traités au moyen d'une solution de peroxyde d'hydrogène lors de leur production dans un processus de filage par fusion. L'invention concerne également des fils continus de polyoléfine obtenus selon ce procédé et leur utilisation pour la fabrication de surfaces textiles, une teinture subséquente étant possible au moyen de colorants de cuve. Le traitement évoqué ou l'étape de finition qui, selon l'état de la technique, a normalement lieu beaucoup plus tard dans la chaîne de production, permet ainsi d'obtenir un fil continu rendu hydrophile, sans traitement supplémentaire ultérieur tel que, par ex., un traitement au plasma, et sans aucun apport d'énergie supplémentaire. Ce fil peut être traité et ennobli comme à l'habitude selon la pratique industrielle actuelle. Les textiles obtenus selon l'invention présentent une remarquable aptitude à la teinture sans traitement ultérieur selon l'état de la technique. Cette teinture peut être obtenue dans les tons foncés, sans prétraitement supplémentaire, au moyen d'un colorant de cuve selon le procédé Thermosol, et elle présente la haute stabilité à la lumière connue des teintures réalisées au moyen de colorants de cuve.
