Summary: | In
this study, the effectiveness of ozone as an alternative bleaching agent to
hydrogen peroxide was investigated for cotton bleaching. The conventional
method for cotton bleaching uses hydrogen peroxide, therefore; hydrogen
peroxide bleaching was applied for preparing control samples. Ozone treatment
were applied on the fabric for 2 different temperatures (30 °C-80 °C) and one treatment
time (30 minute). The whiteness/yellowness, desizing, tensile strength, weight loss
(%), COD (Chemical Oxygen Demand) values were tested and reported. Considering the
whiteness/yellowness and desizing values of 30 °C-30' and 80 °C-30', the 30 °C-30'
values were better than 80°C-30' values. The reason is probably the less
solubility of ozone gas at elevated temperatures. Conventional peroxide
bleaching yielded higher whiteness values at the studied circumstances however
the COD values were much less for ozone treatment. These values of the hydrogen
peroxide were less suitable for the ecological approach compared to ozone
treatment. |
