The present invention relates to a process and device for treating textile substrates with superficial fluid. The textile substrates take the form of spools of yarn or rolled webs and supercritical fluid flows over and/or through them substantially perpendicularly to their spool or winding axis. The treatment temperature during the treatment period assumes various values. During the treatment period, the treatment temperatures are set by at least two functions of the treatment time and supercritical fluid is conditioned differently at the time the cycle function takes effect.

L'invention concerne un procédé et un dispositif de traitement de substrats textiles avec un fluide surcritique. Les substrats textiles sont présentés sous la forme de bobines de filé ou de bandes enroulées et un fluide s'écoule dessus et/ou les traverse sensiblement perpendiculairement à l'axe de bobine ou d'enroulement. Pendant le déroulement du traitement, la température de traitement passe par différentes valeurs. Pendant le traitement, il est également prévu que les valeurs de la température de traitement soient données par au moins deux fonctions de la durée de traitement, et le fluide surcritique est conditionné différemment au moment où la fonction suivante devient effective.
