Abstract

The continuous treatment of a textile product web with steam includes subjecting a moist product web with the reactive dye applied on it to a steam treatment by bringing the moist product web with the reactive dye on it in contact with overheated water steam having a temperature of 130-230° C. for a steam treatment time of preferably 5 to 60 seconds; transporting the moist product web during the steam treatment at least partially horizontally through at least one treatment chamber; and blowing the hot steam into the at least one treatment chamber onto the moist product web by nozzle boxes arranged above and below the product web. The device for performing this method is also described.
