Effect of Carbon Black and Carbon Active on Color and Physical Properties of Cotton/Nylon Fabric

Nowadays, concealment of textile and equipments in military industries has received specific interest in various countries. In this research, by application of nano- Carbon Black (CB) and micro- Carbon Active (CA) in a specific print formulation on cotton/nylon (Co/PA) fabric to produce khaki color, the required standard Vis-NIR reflectance for a successful obscure for desert environment was matched. Reflectance behavior of samples showed that by application of CB rare value in khaki printing formulations could tune spectral level in order to match the reference khaki reflectance in Vis-NIR range. Air permeability of sample was increased by adding CB particles to the printing paste. Evaluation of contact angle with water depicted that when concentration of carbon absorbing pigments raise, surface contact angle increase and the water entirely absorb at the long time. Also, color fastness of printed samples against washing, light and rubbing were good achieved.
