Ozone was able to bleach the denim jeans and decreased the backstaining without the significant loss of the strength of the fabrics. The combined desizing and enzyme wash followed by the ozone wash is thus a promising finishing treatment for denim jeans. Keywords:ozone, denim, jeans, bio-stoning, indigo, backstaining
How does ozone water treatment work?
Ozone water treatment works by dissolving ozone into water and through the ensuing oxidation of bacteria and other waterborne pathogens. To better understand the process, it is best to first understand how ozone is created. Ozone is born out of oxygen.
What is ozone therapy?
Ozone therapy refers to the process of administering ozone gas into your body to treat a disease or wound. Ozone is a colorless gas made up of three atoms of oxygen (O 3 ).
What are the benefits of ozone therapy for diabetes?
A 2015 study also found that ozone therapy could be helpful for wound healing, a common side effect of diabetes. Ozone therapy may have benefits for people with immune disorders because it appears to help stimulate the immune system.
Can ozone therapy help people with HIV?
A 2018 study found that ozone mixed with blood and injected into people with HIV significantly reduced their viral load over a 2-year period. A lower viral load means less of the virus is present, which can improve long-term health. The study noted that more research is needed on the use of ozone therapy for the treatment of HIV.

What is the effect of ozone treatment on denim fabric?
As more contact of fabric to the machine along with ozone gas, abrade the surface of the denim due to which strength decreases. After the statistical analysis, it is evident that speed and time are the main potential parameters of the ozone washing that influences mainly on the tear strength of the garment.
What is ozone wash denim?
Ozone (O3) is a very strong oxidising agent that can be used to provide all over bleaching of denim garments in a closed, batchwise operation. Ozone is generated on-site by applying, typically electricity or UV radiation to oxygen (O2) and this is fed into the washing machine for processing.

Water Energy Ozone Laundry Systems greatly reduce the environmental impact of traditional laundry operations. Using this method, the garment can be bleached. Bleaching of denim garment is done in a washing machine with ozone dissolved in water.
What is ozone fading?
Ozone fading is a term used as a textile finishing process for denim fabrics. Ozone fading gives the advantage of fading with a minimum or hardly any loss of endurance or strength.
Do ozone laundry systems work?
We have found through testing that ozone does work for removing stains from laundry stains from laundry through an oxidation mechanism, whereby ozone and an OH radical (a breakdown product from ozone and cold water) can both work as oxidants.
Why ozone is calling sustainable denim washing process?
Ozone technology harnesses the natural bleaching capabilities of ozone gas to give a range of overall and specialty bleach effects with substantially reduced environmental impact. Ozone can be used to clean pocket backstaining from normal washing processes, or to bleach denim to a lighter shade.

They also know that there are certain materials that don't do well when exposed to ozone—namely certain textiles, leather, rubber, and certain plastics.
Can ozone bleach clothes?
FACT: Ozone is a not a laundry bleaching agent. A reduction in bleach may be possible because ozone is a better catalyst for bleach than hot water. While ozone activates many laundering chemicals and has a profound effect on the wash process, it is not a laundry bleaching/whitening agent.
What is ozone for washing machine?
An ozone laundry disinfection system uses safe O3 gas at low temperatures instead of high heat or chemicals that can damage garments and linen fabrics. Harnessing the natural power of ozone, this innovative way of washing kills bacteria, moulds, yeasts and viruses and eliminates the risk of cross-infection in laundry.

Color fastness to Ozone (ozone test chamber) is intended for assessing the Ozone resistance of color of textiles of all kinds and in all forms when exposed to atmosphere with certain temperature and humidity. Assessing Ozone Resistance.
What does ozone do to nylon?
This study evaluated the effects of ozone and humidity on the efficacy of nylon and Teflon filters used in the US dry deposition monitoring network. Ozone was shown to reduce retention of nitric acid on nylon filters and high humidity was shown to dramatically increase retention on nitrate on Teflon filters.
What is Laser fading?
Mechanism of laser fading: Laser energy is absorbed as heat and the material rapidly heats leading to melting as a phase change from solid to liquid takes place.
What is ozone in jeans?
Ozone, a selective oxidant with high reduction potential, has proven to decolorize textile effluents and it is especially capable of reacting with indigo. In this study, the effect of ozone on the color change of denim fabrics and on the backstaining of the pocket fabrics was studied. Seven different denim fabrics, dyed with the indigo and mixture of indigo and sulfur dyes, were desized and bio-stoned and thereafter treated with ozone in aqueous medium. The response of the color of the indigo dyed denim fabrics to ozone was stronger in comparison with the fabrics dyed with the mixture of indigo and sulfur dyes. The pocket fabrics backstained during the desizing and bio-stoning and subsequent ozone treatment was able to decrease the backstaining. Ozone was able to bleach the denim jeans and decreased the backstaining without the significant loss of the strength of the fabrics. The combined desizing and enzyme wash followed by the ozone wash is thus a promising finishing treatment for denim jeans.
Does ozone decolorize water?
Ozone was able to decolorize the water during the finishing treatment of denim jeans. It clearly cleaved the chromophores of dye molecules and turned initially blue water to yellowish. This is due to the cleavage of the carbon-carbon double bond of the indigo dye molecule that destroyed the chromophore of the molecule and produced yellow isatin.
What is ozone used for in denim?
Widely used as a bleaching agent, Ozone remains a powerful, secret tool within the denim industries that gave denim garments an unique and distinctive look and feel from other traditional processing.
How is ozone produced?
Ozone is tri-atomic oxygen, it exists in nature within the stratosphere (from a height of 10 kms to 50 kms), small amounts of ozone is constantly being produced by the action of sun's UV radiation that splits oxygen (O2) to from single oxygen atoms. These atoms combine with the remaining oxygen molecules to form Ozone (O3) molecules, which are very effective at absorbing suns UV rays.
Abstract
Nowadays, too much water, energy, chemical substances are consumed for the conventional textile finishing processes and more chemicals are exposed to the environmental load. In our world of diminishing resources, the most ideal way of using the available resources has been inevitable in the name of all living things on earth.
