Abstract
A short study has been conducted to examine the efficiency of different alkaline reduction‐clearing conditions on Ingeo [poly(lactic acid)] fibres, dyed with disperse dyes. The results indicate that the preferred conditions are 15 min at 60 °C in the presence of 2 g/l sodium carbonate and 2 g/l ‘hydros’, conditions which avoid any significant change of shade by colour loss and lead to optimised wash fastness.
