Why do we use ozone in garment finishing?

It breaks down the indigo molecule, to degrade the color and obtain a perfectly sustainable worn out effect: this is why ozone is now a protagonist in the treatment of denim.

Our range includes EGO, the new ozone finishing technology, based on an innovative concept whose strong point is simplicity: of use and maintenance.

The line is completed with OBleach, the patented process that allows to obtain an incredible – and sustainable – “Bleach without bleach”, and O-Zone, the static cabinet that can be used to achieve unique and customizable discoloration effects. In full respect of the fibers and the environment.

THE REAL BLEACH WITHOUT BLEACH

OBleach is the new process patented by Tonello that, using only ozone, “returns to the future” of an authentic, sustainable bleach – because, by eliminating Chlorine and Permanganate, it respects the fiber of the garments and the planet – and decidedly cool, thanks to authentic, contrasted and reproducible effects.

The OBleach process is integrated into the All-in-One System, a single machine that combines the latest finishing technologies: ECOfree 2, NoStone®, UP and Core.

THE CREATIVE SIDE OF OZONE

Tonello’s new O-Zone cabinets are the perfect demonstration of how research and collaboration can result in interesting and creative combinations.

Candiani had the pleasure of being the first brand to test and use this technology for small productions, to create effects on garments, completely safe and sustainable.

In fact, O-Zone allows us to achieve various effects and discolorations that are totally new and responsible. This reflects our present and future philosophy regarding the treatment of jeans.

Tonello ozone washing technologies: denim meets a new idea of sustainability

In denim treatment, every garment tells a story of transformation. The color changes, the surface evolves, and the look becomes more lived-in, more authentic, and closer to the brand identity. With ozone washing technologies, Tonello interprets this transformation in an innovative, responsible way that is deeply aligned with the future of industrial laundry.

Today, ozone is one of the most interesting players in garment and jeans finishing because it makes it possible to work on indigo, degrade color and obtain distinctive aesthetic effects through a more sustainable approach. It is not just a technology: it is a different way of thinking about the process, where performance, creativity and environmental awareness become part of the same vision.

Tonello washing machines and ozone processes are designed to guide laundries, brands and textile companies toward cleaner, more controlled and more contemporary treatments. They are a concrete answer for companies looking for commercial ozone laundry systems, but also a broader perspective: building a new balance between aesthetic result, garment quality and production responsibility.

Why ozone matters in garment and jeans finishing

Denim is a living material, capable of changing its identity through treatment. To obtain worn effects, lightening, bleaching and contrasts, the industry has traditionally relied on high-impact processes. Tonello has chosen to look further ahead, developing technologies that harness the potential of ozone to achieve effective results while being more respectful of fibers and the environment.

Ozone acts on the indigo molecule and allows the color to be degraded, creating authentic and customizable visual effects. It is a solution that speaks the language of contemporary fashion: more aware, more attentive, and more oriented toward sustainable processes without sacrificing the expressive power of denim.

Within this vision, ozone treatment becomes part of a broader path: reducing impact, improving process control and opening up new creative possibilities for designers, laundries and manufacturers.

A lighter process, a more conscious result

Ozone makes it possible to rethink the way garments are processed. It decomposes rapidly and can help reduce the use of aggressive chemicals, making the process more responsible and closer to the current needs of the textile industry.

For Tonello, sustainability does not mean simplifying the result or limiting creativity. On the contrary, it means designing technologies capable of delivering advanced aesthetic effects, while preserving garment quality and improving treatment efficiency.

The result is a smarter way to approach finishing: less impactful, more controlled and more consistent with the demand for garments that are beautiful to look at, pleasant to wear and made through more responsible processes.

From worn effects to sustainable bleach

In denim, the worn effect is much more than an aesthetic detail. It is what gives character to the garment, makes it recognizable and transforms a fabric into a product with its own personality. With ozone, this result can be achieved through a precise and sustainable technological process.

Tonello solutions make it possible to obtain lightening, contrasts and bleaching effects with a high level of control over the final result. This approach allows the garment to be processed while respecting the fiber, enhancing its appearance and offering new creative possibilities to the denim world.

Ozone treatment therefore becomes an ally for those who want to produce distinctive garments while reducing the impact of traditional processes.

Tonello innovations with ozone

Tonello has developed a range of ozone-dedicated solutions created to meet different needs, all united by the same vision: transforming garment treatment into a more sustainable, effective and creative process. These commercial ozone laundry systems are designed to support modern denim production with greater control and responsibility.

EGO: SUPERIOR OZONE

EGO represents the culmination of a long journey of research, experimentation and improvement. It is Tonello technology dedicated to ozone garment treatments, developed to make the process simpler, more effective and more sustainable.

Its strength lies in simplicity, both in use and maintenance. This simplicity does not reduce the innovative scope of the technology; rather, it makes it more accessible and easier to integrate into the production processes of industrial laundries.

EGO makes it possible to significantly reduce water consumption compared with traditional discoloration methods and helps simplify wastewater treatment operations. It is a technology designed to improve the process, lighten its impact and offer new opportunities in denim treatment.

OBleach: TRUE BLEACH WITHOUT BLEACH

OBleach is Tonello patented process that interprets bleach in a new key: authentic, sustainable and contemporary. Using ozone alone, it makes it possible to achieve a bleach effect without chlorine and permanganate, while respecting garment fibers and the planet.

It is a technology that combines aesthetics and responsibility. The effects are authentic, contrasted and reproducible, designed to meet the creative needs of denim without giving up a more conscious process.

OBleach is part of the All-in-One System, Tonello vision that integrates the latest finishing technologies into a single machine. It is an advanced approach in which treatment becomes more efficient, more flexible and more sustainable.

O-Zone: THE CREATIVE SIDE OF OZONE

O-Zone expresses the most experimental and creative side of ozone. It is the Tonello static cabinet designed to obtain unique, customizable and sustainable discoloration effects, opening up new possibilities in garment treatment.

This technology shows how research and collaboration can generate original solutions, also suitable for smaller-scale production and specific creative needs. O-Zone allows garments to be treated with a visual, expressive and responsible approach, in line with Tonello present and future philosophy for jeans treatment.

A technological choice, but also a cultural one

Choosing Tonello ozone processes means looking at industrial laundry not only as a production space, but as a space for innovation. Every treatment can become more efficient, every garment can acquire a stronger identity, and every process can help reduce the overall impact of production.

Ozone technology does not replace creativity: it amplifies it. It allows companies to obtain recognizable visual effects, control the result more effectively and work with greater attention to resources, operators and the final consumer.

For this reason, Tonello continues to invest in the development of solutions that combine research, sustainability and denim culture. Because the future of garment treatment is not only about more high-performing machines, but also about a smarter way to imagine the entire process.
