摘要

In this study, the effects of ozone desizing and bleaching on the hydrophilicity and whiteness of terry fabrics were investigated. The results were compared with those obtained after conventional desizing and bleaching (hydrogen peroxide bleaching). The test samples contain two side piled woven terry cloths of four different areal weights. The ozone desizing and bleaching process was carried out at fixed PH values (6) in four different ozonation times and two different ozone doses. The rate of water pickup in fabrics was 60%. It has been determined that as ozonation time and the ozone dose increase, the degree of whiteness and water absorption of the terry fabric increases. However, the increase in the ozonation time did not cause a significant change in the low ozone doses; the change in the ozonation time at high ozone doses is causing a marked change in the investigated properties of the towel fabric. The degree of hydrophilicity and whiteness achieved after ozonation was found to be close to the results obtained in conventional bleaching. However it was seen that although acceptable water absorbency was obtained by the ozone desizing method, these values were lower than those of the conventional desizing method. Ozone bleaching and desizing do not require the consumption of water, the consumption of heat energy, and the use of any chemical additive that harms the environment with its wastes. As a result, owing to ecofriendly, saving energy and acceptable fabric properties with regard to whiteness and absorptivity, ozone bleaching can be applied instead of the conventional bleaching and desizing method.
