Cotton fabric was treated by CO2 laser under different parameters, before and after dyeing with reactive dye. Color properties, including reflectance, K/S sum and CIE L*a*b* of treated fabrics were evaluated through spectrophotometer. The dyed and then laser treated fabric (D/L) revealed lighter, more greenish and less bluish color. The laser treated and then dyed fabric (L/D) showed different results. This indicates that different treatment approaches have different influences on color properties of cotton fabric.
