Abstract: A method for imparting the multiple functions of water- and oil-repellency, soil-releasing properties and anti-bacterial properties to a mixed or blended fabric is provided including: (a) treating a mixed or blended fabric of polyester/rayon by dipping the mixed or blended fabric in a treating solution which includes, based on the weight of the mixed or blended fabric, 1 to 10 wt. % of phenolic antibacterial agent, 2.5 to 5.0 wt. % of a first fluoric compound, 3.0 to 6.0 wt. % of a second fluoric compound, different from the first fluoric compound, 0.3 to 0.5 wt. % of melamine resin as a cross-linking agent and a buffer, the rate of absorption of treating solution by the mixed or blended fabric being maintained at 50.+-.5%, (b) drying the treated fabric, and (c) thereafter heat treating the treated and dried fabric.
