Abstract (en)

[origin: EP0137989A2] The hydroextracted moist textile material passes into an application stage where a purely additive application of liquor takes place, after which the material is wound up in roll form and batched. Such a process eliminates the need for a drying stage between the hydroextraction and the application stage, and gives particularly uniform application results.
