KEY FEATURES:

  • lower water and chemical consumption and time loss of the ozonation process than conventional wet processes.
  • No need to store chemicals compared to the other conventional methods.
  • No dangerous waste because of the decomposition of ozone into oxygen.
  • No halogenated organic compounds (AOX) in wastewater.

Ozone in the Textile Industry

Textiles utilize several wet and dry processing techniques to achieve desired effects. The techniques include pumice stone washing, enzyme washing, bleaching, and mixed washing. The textile dyeing and finishing industry consume the most energy and water. The production of jeans consumes approximately 350 million m3 of water every year. Also, there is a large amount of wastewater and solid waste generated by the textile industry. Chemical-free and dry-bleaching technologies, such as ozonation, are therefore the best economic and environmental solutions.

Ozonation is a simple and “green” process because it does not require steam and water. Therefore, it greatly reduces process time, energy consumption, and the amount of water and wastewater. Ozone decomposes indigo and other dyes because of high oxidation potential. In addition to denim washing, it is generally applicable to the treatment of any textiles. Absolute Ozone – ozone generators can commercially provide a bleaching effect. It is like a washing machine without water for fading of color. 

Ozone is one of the strong oxidant agents. But with the advantage of being environmentally friendly. After ozonation, loss of fabric strength is not a problem because ozone is unstable, and it decomposes indigo primarily.

Advantages of ozone in the textile industry

Ozone treatment proposed an economical solution to environmental pollution from textile processes.

  • Compared to conventional wet processes, ozonation consumes less water and chemicals and takes less time.
  • Chemicals are not stored as with other conventional methods.
  • Because ozone decomposes into oxygen, there is no hazardous waste.
  • There are no halogenated organic compounds (AOX) in wastewater.
  • Different patterns and fading effects soon in denim washing.
  • Improving the dyeability of fibers.
  • More ecological antifelting treatment than conventional methods.
  • Higher whiteness than conventional bleaching processes.
