PURPOSE: To economically adjusting wash water flow and steam feed through such a procedure that replacement factors are calculated based on the respective temperatures and washing effects of plurally connected countercurrent wash tanks and a linear relationship between the replacement factors and temperatures is determined to decide both the replacement factor and temperature corresponding to desired washing effect. CONSTITUTION: This method for adjusting both the flow and temperature of wash water in washing fabric webs throughout their widths through bringing hot wash water countercurrent-fashion into plurality connected wash tanks in series, comprises the following procedure: first, both the washing effectϕand flow of one of the wash tanks are measured; secondly, replacement factor M given by the equation is calculated (wherein n is the number of the wash tanks, and F is a numerical value per s, i.e., a number obtained by dividing the volume of wash water by the volume of the water carried by webs to be washed); subsequently, for each of the other wash tanks, the corresponding replacement factor M is calculated in a similar way, and the linear relationship between these replacement factors M and temperature is determined, then based on the relationship, both the replacement factor and temperature needed for desired washing effect are decided.
