Abstract:

In an attempt to provide a method of achieving near infrared camouflage with textiles having wide military applicability, proprietary infrared absorbers aminium radical cation type IR-99 and IR-117 were applied to Nylon 6,6. Pre-dyeing the nylon with an acid dye, or pre-treating it with certain organic salts increased the uptake of infrared absorber, but light stability was poor in all cases. Further work utilizing this approach does not appear warranted until infrared absorbers having better lightfastness characteristics are available.
