Coloration of Polyamide-6, 6 Fabric with Carbon Black Nano Particle for Camouflage Textiles of Simultaneous Spectrum Probe in Visible and Near Infrared

Abstract

Camouflage textiles on simultaneous spectrum probe in Visible-Near Infrared (Vis-NIR) have been explicated under optical mechanism of reflection and chromatic hue. Polyamide 6,6 (PA-6,6) fabric was experimented for liquid phase formulation and coloration in acidic medium of seven standardized PH (0-6) with Carbon Black Nano Particle (CBNP). International commission on illumination (CIE) color value (L*, a*, b*), Kubelka-Munk (K-M) reflection and reflection (%) of CBNP dyed PA-6,6 fabric was investigated with optical condition of specular reflectance, color measurement spectrophotometer from 400 nm to 700 nm. The K-M reflection and reflection (%) of CBNP dyed PA-6,6 fabric was also measured with optical property of diffuse reflectance, Fourier transform infrared spectroscopy from 1000 nm to 2500 nm. Vis-NIR reflection (%) was observed comparatively lower for PH 4 to 5. Similarly, K-M reflection of simultaneous spectrum probe in Vis-NIR was found higher for PH 4 to 5. Raw CBNP and CBNP modified PA-6,6 fabric was also examined for oxidation property, aggregation property, coloring property and air permeability by scanning electron microscopy. Hence, this experimentation was only focused on color properties of CBNP modified PA-6,6 fabric in terms of camouflage textiles.
