Abstract: A process for imparting durable water and oil repellency and durable soil release characteristics comprises the application of an aqueous mixture having a water repellent component such as a fluorocarbon polymer and a separate hydrophilic soil release polymer to a textile substrate, followed by a drying step.

Polyamides, aramids, polyesters, and poly/cotton substrates, when treated according to the present process, have all yielded improved performance with respect to durable water and oil repellency and durable soil release characteristics. A novel mixture or bath and novel treated substrates are also disclosed.
