Popis:	In this study, 8 novel pyrazole disperse dyes which were synthesized in our previous work [1] were applied to polyethylene terephthalate (PET), poly (lactic acid) (PLA) and polyamide 6.6 (PA 6.6) fiber fabrics and their colorimetric and fastness properties were evaluated. The measured a*, b* and hue angle (ho) values of all dyed fabrics exhibited yellow, orange and red colour shades. Quite high colour strength values (K/S) were measured particularly for dyes containing substitute groups; p-OCH3 and o-OCH3. Shade changes of all fabrics after standard washing and sublimation tests were in the commercially adequate range. All dyed PET, PLA and PA 6.6 fabrics exhibited commercially acceptable fastness staining performances with very good to excellent levels. Synthesized novel disperse dyestuffs led to moderate to high light fastness levels particularly in the case of PLA and PET fabrics.
