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 the desired effects. These methods include pumice stone, enzyme, bleaching, and mixed washing. The textile dyeing and finishing industry consumes the most energy and water. Producing jeans uses approximately 350 million m3 of water every year. The sector also generates a large amount of wastewater and solid waste. Therefore, chemical-free and dry-bleaching technologies, such as ozonation, are the best economic and environmental solutions.
Ozonation is a simple and “green” process because it does not require steam or water. Therefore, it dramatically reduces process time, energy consumption, and the amount of water and wastewater used. Because of its high oxidation potential, ozone technology decomposes indigo and other dyes. In addition to denim washing, it generally applies to treating textiles. Absolute Ozone – ozone generators can commercially provide a bleaching effect. It is like a washing machine without water for fading of colour.
Ozone is one of the potent 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.

Ozone treatment proposed an economical solution to environmental pollution from textile processes.
- Environmental sustainability: Ozone offers an eco-friendly alternative to traditional wet processes, reducing water and chemical consumption and eliminating hazardous waste. It decomposes into oxygen, leaving no harmful residues.
- Energy efficiency: Ozone requires less energy than conventional methods, contributing to overall energy savings in textile production.
- Colour removal and oxidation: Ozone’s high oxidation potential effectively decomposes indigo and other dyes, leading to enhanced colour removal and oxidation of contaminants in textile processes.
- Versatility: Ozone is not limited to denim washing and can be applied to a wide range of textile applications, improving dyeability and achieving various fading effects.
- Process control: Ozone dosage can be precisely controlled, ensuring consistent and optimal treatment results.
- Reduced water usage: Ozone significantly reduces water consumption in textile processes, addressing the industry’s water-intensive nature.
In recent years, the adoption of ozone technology in the textile industry has surged due to its sustainability and cost-effectiveness. The process aligns with global environmental regulations and gives manufacturers a competitive edge by reducing operational costs. As consumers become increasingly eco-conscious, the demand for textiles processed using ozone technology is expected to rise, positioning it as a key player in the future of textile processing. Integrating ozone technology can also enhance a brand’s reputation by showcasing a commitment to green practices and innovation.
