"Enhanced PAA Bleaching of Cotton by Incorporating a Cationic Bleach Activator,"
Coloration Technology, Vol. 123, #4, pp230-236

Description: 4-Factor Design to determine effects on whiteness of cotton.
Factors: Temperature (40-80C)
Bleach Activator - TBBC  (0-3 %owf)
pH    (6.5-8.5)
Paracetic Acid - PAA  (ml/l)
Response: Whiteness Index

Note: Polynomial Regression fit on coded levels, not raw levels
