Abstract: A process for making a polyamide substrate characterized by enhanced breaking strength and fade resistance is disclosed. The process features the steps of treating a polyamide substrate, preferably a nylon 6 substrate having a hindered amine light stabilizer chemically bound thereto, with an effective amount of an ultraviolet inhibitor, an antioxidant and optionally, a dye, in the presence of a swelling agent for the polyamide that is also a solvent for the ultraviolet inhibitor and the antioxidant to impart high breaking strength to the substrate. A life preserver or other type of buoyancy device may be made from the process. A polyamide fabric comprising a dye, an ultraviolet inhibitor and an antioxidant also is disclosed. When a polyamide fiber of the present invention is exposed to sunlight, the useful life of the fiber is greatly increased compared to untreated polyamide fiber.

Abstract: A process for dying materials containing natural or synthetic polyamides is disclosed. The process includes immersing the materials to be dyed in a dye bath containing an acid dye. The pH of the dye bath is initially at a level that substantially inhibits the dye from being absorbed by the polymer. In accordance with the present invention, however, an acid producing composition is added to the bath which gradually reduces the pH of the bath and allows for uniform diffusion of the dye into the polymer. The acid producing composition of the present invention is a maleate ester, which, in one embodiment, is the reaction product of maleic acid or maleic anhydride and a glycol.
