Abstract (en)

[origin: EP1046738A1] Continuous textile fabrics (1) are scoured by passing them upwards through a vertical shaft (6) without contacting the sides the top (7) the shaft is fed across the full width with wash liquor (10) by an overflow system. The liquid (10) is retained at a level at the bottom (8) where it is drawn off so that the shaft remains completely filled. An Independent claim is also included for equipment for carrying out this process, with an overflow liquid feed at the top shaft and a vessel that is kept filled at the bottom. Several shafts can be used in series, with an appropriate change in level provide flow by gravity. The gap between the sides of the shaft (6) is adjustable below 15 mm, e.g. optimal results were obtaine with 6 mm. The equipment can form the pre-wash stages of conventional plant.
