Highly durable outdoor textile fabric having improved resistancy and repellency

A process for preparing an outdoor textile fabric comprising the steps of:

• (a) selecting an untreated textile fabric having a front surface and a back surface;
• (b) treating the front surface of the untreated textile fabric with an aqueous treatment composition comprising from about 0.1 weight percent to about 5 weight percent, based on the total weight of the aqueous treatment composition, of a fluorochemical agent and from about 0.1 weight percent to about 10 weight percent, based on the total weight of the aqueous treatment composition, of a crosslinking agent comprising a melamine/formaldehyde or phenol/formaldehyde resin and wherein the aqueous treatment does not contain a urethane latex or an acrylic latex and wherein the treatment results in a first chemical layer being contiguous with the front surface;
• (c) drying the textile fabric to obtain an initially treated fabric;
• (d) applying to the back surface of the initially treated fabric, wherein the back surface of the initially treated fabric is uncoated, a second treatment composition comprising from about 40 weight percent to about 85 weight percent, based on the total weight of the second treatment composition, of a polyurethane wherein the application results in the second treatment composition being contiguous with the back surface;
• and
• (e) drying the initially treated fabric to obtain the outdoor textile fabric.
