Disclosed is a method of treating non-keratinous fibers using a composition comprising an amide and/or alkyl ammonium carboxylate salt wherein the treating method improves the robust performance of the non-keratinous fibers and simultaneously maintains and/or improve the appearance or look such as color, shine, form, and shape of the fibers even after prolonged use. The method of protecting colored non-keratinous fibers from fading using the composition comprising an amide and/or alkyl ammonium carboxylate salt is also disclosed.

The invention is related to azetidinium-containing copolymers and vinylic monomers and their uses in formation of non-silicone hydrogel coatings on silicone hydrogel contact lenses.
Hydrated silicone hydrogel contact lens having a layered structural configuration: a low water content silicone hydrogel core (or bulk material) completely covered with a layer of a water-rich (e.g., a water content greater than 80%), hydrogel totally or substantially free of silicone. A hydrated silicone hydrogel contact lens of the invention possesses high oxygen permeability for maintaining the corneal health and a soft, water-rich, lubricious surface for wearing comfort.

The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves autoclaving, in a sealed lens package, a silicone hydrogel contact lens having a base coating of polyacrylic acid thereon in an aqueous solution in the presence of a water-soluble, crosslinkable hydrophilic polymeric material having epoxide groups, for a period of time sufficient to covalently attach the crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one epoxide group and one of the carboxyl groups on and/or near the surface of the silicone hydrogel contact lens.
