Revolutionises denim finishing using ozone gas to achieve stone-wash, bleach, and vintage effects without pumice stones, sodium hypochlorite, potassium permanganate, or enzyme treatments. Process exposes denim fabric to controlled ozone concentrations in sealed chamber, selectively fading indigo dye. Benefits: 50-70 percent water savings, 30-40 percent energy reduction, zero chemical discharge to effluent, faster processing time, consistent repeatable results. Used by denim manufacturers complying with ZDHC standards required by European buyers including H&M Zara Levis.

Frequently Asked Questions
An ozone denim machine is a garment processing machine that treats denim fabric with ozone gas to achieve the faded, stonewashed appearance traditionally produced by pumice stone or potassium permanganate (KMnOâ‚„). Ozone selectively oxidises the indigo dye on the surface of denim threads, producing a washed-out look without water consumption or chemical addition.
Ozone India Technology denim machines are available in 30 kg, 50 kg, 100 kg, and 200 kg drum capacities, matching standard industrial garment washing machine specifications. Custom capacities are available for OEM projects.
Yes. Ozone denim finishing eliminates the use of potassium permanganate (KMnOâ‚„) and pumice stone — both restricted under ZDHC MRSL and unsupported by GOTS. Since ozone decomposes to oxygen without chemical residue, there is no restricted substance discharge, enabling GOTS-certified denim production.
Ozone denim finishing reduces water consumption by 50–70% compared to conventional stone wash and 80–90% compared to KMnOâ‚„ wash processes, because the fading step is done dry in the ozone drum with no water. Only the post-wash rinse uses water.
