In a process for impregnating a fibrous, woven, knitted or nonwoven fabric with an aqueous liquid, in particular of the type containing a treatment agent, the textile fabric (6) is placed on an endless cloth (4) permeable to liquids, the liquid is poured under gravity onto the textile fabric in the form of a liquid curtain or sheet transverse to the direction of motion of the latter, and a vacuum slit (13) arranged below the cloth produces a vacuum sufficient for at least part of said liquid to pass through the textile fabric. The rate at which the liquid is poured, defined with respect to the weight of the fabric passing below said liquid sheet, is greater than a given value above which the impregnation rate is a function of said depression and independent of the poured quantity, thus permitting uniform impregnation and easy control of the impregnation rate.
