  Abstract

The present work investigates the effect of solvents with known solubility parameters on polyester filament yarn. The polyethylene terephthalate (PET) fibers were pretreated in 10 different solvents initially at 30 oC and 50 oC before dyeing procedure. The degree to which the solvents affected the morphological structure of the PET fibers was examined using scanning electron microscopy (SEM). The degree of cracks and voids increased for all the samples after pretreatment. The development of cracks and voids was much more for benzyl alcohol treated samples. The degree of liquid retention was least in chloroform, acetone, and n-hexane treated samples while the highest retention was observed in benzyl alcohol treated samples. This is attributed to their solubility parameters in relation to that of the polyester fiber. The specific stress and dye exhaustion was determined as a function of time of treatment. The dyeing kinetics for all the solvent pretreated samples showed similar pattern. However, an optimum dye exhaustion of about 25 % was obtained for the untreated sample (control). The dye exhaustion obtained for benzyl alcohol and dimethyl formamide treated samples was 94 % and 82 %, respectively, which was very high compared to the other pretreated samples.
