where E* is the CIELAB color difference between batch andstandard. Here L*, a*, b* and hence E* are in commensu-rate units. L* denotes the difference between lightness (whereL* = 100) and darkness (where L* = 0), a* the difference betweengreen (−a*) and red (+a*) and b* the difference between yellow(+b*) and blue (−b*) (Park, 1993). All measured samples showed amaximum absorption wavelength value (max) at 400 nm. The colorfastness to washing, light, crocking, perspiration, and water of thedyed samples were determined according to AATCC Test Method61-2010, ISO 105-B02: 1994, AATCC Test Method 8-2007, AATCCFig
