Abstract :Because of the savings in energy consumption and the shortened process time, the use of microwave energy in textile wet processes has become an important research topic in the eco-friendly studies. In this experimental work, 100 % isotactic polypropylene insert ignore into journalissuearticles values(iPP); which is widely used in technical textiles, 80/19/1 and 60/30/10 % iPP/ LLDPE insert ignore into journalissuearticles values(linear low-density polyethleylene polymer fibers); / EVA insert ignore into journalissuearticles values(elastomer of ethylene-vinyl acetate); ternary polymer blend fibers were dyed by conventional and microwave heating methods under atmospheric condition with C.I. Disperse Yellow 114, Red 60 and Blue79. The colour yields of conventionally dyed samples were compared to those of the dyed samples using the microwave heating. Finally, the high proportion of EVA in triple fiber mixes can be improved the coloristic properties of ternary polymer blend fiber. The colour fastness to light was quite good for dyed samples by microwave heating with C.I. Disperse Blue 79, to washing and rubbing were adequate for all dyed samples. The process time was reduced almost 90% by microwave heating.
