Claims
- 1. A method for treating nylon fibers, which method comprises:
(a) reacting a protective entity with a moiety having the capability of forming a covalent bond with a nylon fiber to create a modified protective entity that is adapted to form a covalent bond with a nylon fiber; (b) adding the modified protective entity to a dyebath containing one or more dyes selected from the group consisting of fiber reactive dyes, acid dyes, acid-premetalized dyes and disperse dyes; (c) applying the dyebath to nylon fiber at a pH within the range of about 0.5 to about 6.5; (d) applying an alkali solution to the fiber.
- 2. The method of claim 1 which includes treating the modified protective entity with an alkali solution at a pH of about 9.5 so as to previnylize said modified protective entity prior to its addition to the dyebath.
- 3. The method of claim 1 wherein the protective entity is selected from the group consisting of stain-blockers, chlorine resist agents and anti-oxidants, fire retardants and flammability protectors, ultraviolet radiation absorbers and other lightfastness protectors, antimicrobial and anti-bacterial agents, gas/fume fade protectors, mildew protectors, anti-stats and soil resist agents.
- 4. The method of claim 1 which includes reacting the protective entity with a vinyl sulfone ester having the capability of forming a covalent bond with a nylon fiber to create a modified protective entity that is adapted to form a covalent bond with a nylon fiber.
- 5. The method of claim 4 wherein the vinyl sulfone ester is acetimydophenylhydroxyethylsulfone sulfuric acid ester.
