A method for treatment of a textile substrate (32; 171), at which the textile substrate (32; 171) is arranged in a treatment device and there treated with sprayed aqueous treatment bath, that contains chemicals and treatment agents needed for the respective treatment in a concentration chosen for the respective treatment, and during the treatment of the textile substrate (32; 171) the treatment bath which is not adsorbed by the textile substrate (32; 171) is removed, collected and sprayed again until the treatment bath is sprayed on the textile substrate as far as possible, characterized in that a) at the beginning of the treatment, the moisture of the textile substrate (32; 171) to be treated is adjusted to 40 % to 180 %, preferably between 60 % and 160 %, referred to the dry weight of the textile fabric (32; 171) to be treated, b) that the textile substrate (32; 171) is heated to a temperature needed for the respective treatment previously, simultaneously herewith or hereafter, c) that a treatment bath volume adjusted per time unit is determined by pumping the treatment bath via a bypass calibration line from at least one vessel for preparing the treatment bath through a pressure pump, a flowmeter and a first control valve, a heat exchanger and an open second valve are conveyed until the treatment liquor volume to be adjusted per time unit is reproducibly supplied to the liquor receiving container through the bypass calibration line, a control valve back into the at least one vessel for preparing the treatment bath, d) that hereafter the treatment bath volume of the respective treatment determined per time unit is linearly or progressively sprayed on the textile substrate (32; 171) for the predetermined treatment time, so that due to the spraying of the treatment bath volume during the treatment the moisture of the textile substrate is linearly or progressively increased thus far, that the treated textile substrate (32; 171) has final moisture values between 70 % and 300 %, preferably between 140 % and 260 % at the end of the treatment, relative to the dry weight of the textile substrate to be treated, e) that during the spraying of the treatment bath on the textile substrate the textile substrate is transported in the treatment device with an even speed as an endless fabric strand, or reversibly as a fabric reel in a width state, or, if the textile substrate is designed as a yarn package, the sprayed treatment bath is transported through the textile substrate or through the yarn package by rotation of the fabric reel or the yarn package, f) and that the treatment bath which is isolated and not absorbed during treatment is removed from the textile substrate, collected and sprayed again until the predetermined treatment time is elapsed or the treatment bath is sprayed on the textile substrate as far as possible. a) at the beginning of the treatment, the moisture of the textile substrate (32;
