Abstract

The dyeing behaviors of poly(ethylene terephthalate)(PET) bulky yarns, DTY(draw textured yarn) and SSY(latent crimped yarn), were investigated with different energy type disperse dyes compared with those of SDY(spin draw yarn). The maximum exhaustions of E-type disperse Red 60, Blue 56 and Yellow 54 on SSY were 99%, 94% and 93%, respectively. The maximum exhaustions of S-type disperse Red 179, Blue 79 and Orange 30 on SSY were 96%, 97% and 97%, respectively. The K/S values of SSY were significantly higher than those of DTY and SDY in all energy type of disperse dyes. The knit fabric composed of SSY became bulky at the end of high temperature dyeing process because of their thermal shrinkage property due to melt viscosity difference.
