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.

Wet processing of textile materials consumes a large amount of electricity, fuel, and water. Therefore, greenhouse gas emissions and contaminated effluent are environmental problem. The most of the governments in the world warn all the industrial sectors containing textile manufacturing to be careful about environmental pollution. Increasing in public awareness of environment and competitive global market forces the textile industry to manufacture textile products environmentally. Environmental pollution in textile wet processes can be reduced by four main ways. They are process optimization (reducing in water, chemical energy consumption, and time loss), use of ecofriendly chemicals, reuse of water, and new technologies like ozone and plasma technologies, transfer printing, enzymatic processes, etc. This chapter is about the use of ozone in the textile industry.

The feasibility of reuse waste alkali solution from rayon manufacturing process to replace solid sodium hydroxide for cotton fabric one-bath-one-step pretreatment had been investigated. Under alkaline condition, hydrogen peroxide decomposition rate could be accelerated by a little amount of cobalt chloride. To obtain a similar decomposition value of hydrogen peroxide, the required temperature for waste alkali solution was lower than that of solid sodium hydroxide, and the lower value is about 10°C. The pretreatment temperature could be reduced by 15°C when waste alkali solution was used as alkali agent to replace solid sodium hydroxide, while the treatment conditions should be strictly controlled to diminish fiber damage. According to the demands of dyeing and printing products, a desired pretreated cotton fabric could be successfully prepared when the alkali waste from rayon manufacturing process was used as substitute for solid sodium hydroxide in one-bath-one-step pretreatment of cotton fabric.
