Abstract :In the present study, the applicability of the ozone bleaching process at the jigger machine and the effect of chosen ozonation parameters on the whiteness degree of the 100% cotton woven fabrics were investigated. For this aim, the effects of the ozone gas on the bleaching degrees of the samples in terms of the ozonation conditions insert ignore into journalissuearticles values(in the air with dry and moist fabrics, and in the water);, the ozonation time insert ignore into journalissuearticles values(number of the passage);, the production capacity of the ozone generator insert ignore into journalissuearticles values(6 g/h, 12 g/h, 18 g/h); and the method of ozone feeding to the jigger insert ignore into journalissuearticles values(via rubber diffuser or stone diffuser); were researched. In addition, in order to examine the effect of rinsing process on the whiteness degree of the samples, the rinsing process was applied after ozonation applications. At the end of the study, the whiteness degrees insert ignore into journalissuearticles values(as Berger); of the samples were measured and compared with the conventional hydrogen peroxide bleaching. In addition, the statistical analysis was carried out in order to research the effects of the investigated parameters on the output. The results showed that it was possible to apply the ozone bleaching process at the jigger and all of the investigated ozonation parameters had effect on the results at different levels. The best bleaching effect was obtained at the longest ozonation time and the highest production capacity of the ozone generator for the ozone application in the water.
