Described is a process for continuously dyeing high tenacity nylon 6,6 fabrics including the sequential steps of applying to a high tenacity, highly crystalline nylon 6,6 fabric whose fibers have a breaking tenacity in the range of 6.0 to 10 g/denier and an aqueous dyebath containing a tinctorial amount of at least one dye. The dyed fabric is then steamed with superheated steam at atmospheric pressure and at temperatures greater than 100 DEG C., e.g., 100 DEG to 160 DEG C., for a time sufficient to fix the dye to the fabric, usually up to 3 minutes. Following steaming, the dyed fabric is washed to remove any unfixed dye, then dried.
