A process for continuously impregnating a textile substrate involving: (a) providing an impregnating compartment through which the textile substrate is passed; (b) providing an impregnating liquor present in the impregnating compartment, the impregnating liquor containing: (i) lye; and (ii) an oxidative bleaching agent; (c) providing a bypass member for redirecting fluid; (d) branching off a portion of the impregnating liquor from the impregnating compartment, thus forming a branched off portion of impregnating liquor; (e) heating the branched off portion of impregnating liquor to form a heated branched off portion of impregnating liquor; (f) providing a filtration unit; (g) filtering the heated branched off portion of impregnating liquor through the filtration unit to form a filtered impregnating liquor; and (h) delivering the filtered impregnating liquor to at least one sensor used for determining the concentration of the impregnating liquor.
