| 摘要 |
A process for arresting or attenuating ultraviolet induced damage to nylon fibers comprising dyeing cationic dyeable nylon fibers at a pH of about 2.5 or less with an acid dye, a fiber reactive dye or premetallized acid dye and, subsequent to exposing said fibers to fiber damaging amounts of ultraviolet light, applying a neutralizing aqueous solution having a pH of about 7.5 or greater to said fibers, thereby arresting or attenuating ultraviolet induced damage to said nylon fibers. The nylon fibers may be in a carpet which may be treated after installation.
