ABSTRACT:
Process and apparatus for applying in a continuous and level manner aqueous impregnating liquors to water-wet textile goods to prevent unlevelness of the liquor applied to the goods. This is accomplished by partly or completely exchanging the moisture 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 constant value. The new technique makes it possible to dispense with the customary intermediate drying stage after the pretreatment.
