Treatment of dyed nylon fibers to prevent degradation caused by ultraviolet light |
摘要 |
The effects of ultraviolet induced damage to cationic dyeable nylon fibers dyed at a pH of about 2.5 or less with an acid dye, a premetallized acid dye or a reactive dye are arrested or attenuated by applying to the dyed fibers either before of after exposure to ultraviolet light a neutralizing aqueous solution having a pH of about 7.5 or greater and heating the fibers.</PTEXT>
