In this study the influence of the different fluorescent brightener Periblanc
BA concentrations on the degree of knitted cotton fabric whiteness was
investigated. Two consecutive experimental runs were performed. The first was
the bleaching of the knitted cotton fabric with hydrogen peroxide using the
methods of two and single bath exhaustion while the second was the optical
bleaching with fluorescent brightener Periblanc BA using the exhaustion
method. CIE Whiteness Index and Tint value were measured on the Color-Eye
3000 spectrophotometer at the standard illuminant D65 (Ice-Texicon, d/8,
D65/10°) while K/S values were determined using the Kubelka Munk equation.
The results show that cotton fabric bleached with fluorescent brightener
Periblanc BA after bleaching with hydrogen peroxide using two bath exhaustion
method has higher degree of whiteness (118.8) with a reddish tint in
comparison to the one bleached with hydrogen peroxide using single bath
method (106.1).
