dyeing at 295 nm, respectively.
To evaluate the dyeing performance, the color strength (K/S) and
CIELab value of the dyed samples was measured by using a Minolta
Lab Color test cm2300d spectrophotometer with illuminant D65
and 10 observer. This apparatus measures the light reflection
spectrum and converts it into L*, a*, and b* Cartesian coordinates of
a three-dimensional space map of all colors
