Color measurement
The dyeing quality was evaluated using the color strength
parameter (K/S). This parameter represents the depth of color
obtained when a standard weight of colorant is applied to a substrate
under specified conditions.
The determination of the samples was carried out on Spectro-
Flash SF300 spectrophotometer (illuminant D65/10◦ observer)
with data Master 2.3 software (Datacolor International, USA). K/S
value was determined at 410nmusing the Kubelka–Munk equation
