Dyeing and washing fastness properties of polyurethane-impregnated polyester (PU-impregnated PET), and the distribution of two disperse dyes between PET and PU film were studied to investigate the effect of PU portion to exhaustion and washing fastness. Dyeing properties of PU-impregnated PET were quite different with those of PET: PU-impregnated PET absorbed disperse dye linearly from the early stage of dyeing to equilibrium, and it exhibited excellent build-up property up to 4 %owf dyeing. The absorbed dye on PU film at early dyeing stage migrated to more substantive PET at the temperature higher than 115℃. The amount of exhausted dye on PET portion was larger than on PU film and the distribution ratio was 2.08~2.34. The grade of washing fastness of PU-impregnated PET was the same as or lower by 0.5~1 grade than PU film whose washing fastness was lower by 0.5~1 than PET.
Abstract

The grade of washing fastness of PU-impregnated PET was the same as or lower by 0.5~1 grade than PU film whose washing fastness was lower by 0.5~1 than PET.
