Abstract

L'invention concerne un procédé de traitement d'un substrat textile, selon lequel le substrat est disposé dans un appareil de traitement où il est traité au moyen d'un bain de traitement aqueux. Au début du traitement, l'humidité du substrat textile est ajustée à une valeur d'humidité spécifiée, le volume du bain de traitement pulvérisé par unité de temps et sur le substrat respectif étant déterminé précisément de sorte qu'à la fin du traitement le substrat textile traité présente une humidité spécifiée. Les dispositifs utilisés à cet effet permettent la mise en oeuvre du procédé pour un substrat textile sous forme de brin, de large bobine de bande de matière et sous forme de bobine de matière.
