Ozone Treatment: An Alternative Approach to Desizing
Abstract
It
is essential to remove the sizing agents (desizing) prior to coloration for
woven textile materials. Although desizing is a common pre-treatment practice,
environmental load of the process effluent is usually high. Therefore, new
approaches are required in order reduce the environmental impact. Ozone
treatment is a novel subject for textile finishing. In this study, ozone gas
was utilised for desizing purpose. Various ozone treatment periods (15-30 min)
were applied for desizing. Also conventional enzymatic desizing was applied as
the control treatment. Desizing degree, whiteness, mote count, strength and
chemical oxygen demand (COD) tests were applied. The results were evaluated by
the graphics and the statistical data analysis method ANOVA. Desizing rate
increased as the ozone treatment time increased. Also the mote count
considerably decreased by the ozone treatment. Moreover, the COD values of the
ozone process were less compared to conventional enzymatic treatment. Therefore
it was concluded that ozone treatment can be considered as an environmentally
friendly alternative in order to other chemical pre-treatment processes like
desizing, hydrophilization, bleaching.
