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 (in the air with dry and moist fabrics, and in
the water), the ozonation time (number of the passage), the production capacity
of the ozone generator (6 g/h, 12 g/h, 18 g/h) and the method of ozone feeding
to the jigger (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 (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.
