Abstract

The distributions of 3 disperse dyes with different molecular structures among polyurethane (PU) and polyester (PET) in dyeing PET-PU blend and which dye structure contaminated less PU portion were studied. The amounts of dyes left substrates after reduction clearing and washing were measured to prove which dye structure had an effect on improving washing fastness. Disperse dye with high molecular weight showed similar distribution onto PU and polyester by dying both substrates with similar rate and less contamination to polyurethane while other dyes distributed to PU faster than to PET had.
