Abstract
C.I.Disperse Blue 284 was applied to dye poly(lactic acid) and the effect of lactic acid stereoisomers on the dye uptake was investigated.High D-isomer concentration is preferable for the improvement of dye absorption.The absorption isotherm can not be ascribed to Nernst absorption,which may be interpreted in terms of dye aggregates.The colour yield of dyed fabric increases with the increase of dyeing temperature.
