Abstract of the disclosure: In the continuous application of impregnating liquors to a wet textile web, there is a risk of the liquor being diluted by the moisture carried over by the textile material from the pretreatment, which, when dyeing liquors are applied, would immediately become visible to the naked eye by there being unlevelness between the ends of the web. There are also problems in respect of the levelness of the goods because of the non-uniform moisture content of the textile material which is a consequence of variable squeezing performance on the pad-mangle across the width of the web. The novel process and device eliminate the prob- lems which hitherto went hand in hand with wet-on-wet application by partly or completely exchanging the mois- ture on the goods by sucking or pressing liquor through the goods and by circulating the liquor to be applied while maintaining its volume and concentration at a con- stant value. The new technique makes it possible to dis- pense with the customary intermediate drying stage after the pretreatment.
