Colourful and antioxidant silk with chlorogenic acid: Process development and optimization by central composite design

Both the conventional one-factor-at-a-time (OFT) optimization, in which one of the factors is varied maintaining the other parameters fixed at constant levels, and the central composite design (CCD) optimization, in which all factors are varied simultaneously, were carried out for silk dyeing with c...
