Abstract: Camouflage characteristics of textile materials are of extreme importance especially when production of personal equipment is in question. This paper presents results of spectral reflection measurements in the wavelength area from 400 nm to 1000 nm, of dyed polyamide cloth samples dyed with specific camouflage dyes and impregnated with polyurethane and chlorosulfonated polyethylene. The comparative results were given for the light green, beige green, dark green, brown and black tone. Apart from this, spectral reflection of non-impregnated polyamide cloth samples was measured as well. The results show that the best camouflage characteristics are those of polyurethane impregnated cloth samples.

Keywords: spectral reflection, polyamide, polyurethane, chlorosulfonated polyethylene.
