ABSTRACT:
A water repellant fabric and a process to produce that fabric is provided. The process comprises; providing a fabric substrate having sites reactive with polymeric functional groups; contacting the fabric substrate with a functional group containing polymer; removing unreacted functional group containing polymer; and recovering a water repellent fabric. The appearance, stiffness and texture of the treated fabric is similar to the untreated fabric and the hand of the treated fabric is excellent.
