Abstract (en)
[origin: WO2023275562A1] A method for improving the colourfastness of a dyed textile is provided. The method comprises the steps of: conveying a dyed textile along a processing line in a first direction; flowing a fluid from a reservoir through the dyed textile on the processing line in a second directly substantially opposite to the first direction; subsequently removing at least 50% of the applied fluid from the dyed textile; removing contaminants from the fluid; and returning the fluid to the reservoir.
