Safely exploit the benefits of TiO2



Archroma launched Perapret AIR, a new light-activated air purification technology for fabrics at the recent Techtextil show in Frankfurt.

Mineral-based Perapret AIR removes airborne pollutants and odors by mimicking the natural process of photocatalysis under normal daytime and artificial light sources.

The chemistry usually used in these applications is nano-sized TiO2 (titanium dioxide), which attacks all organic materials, including textile fiber, and not just pollutants.

Perapret AIR is produced using a unique, patented core/shell technology that partially surrounds the TiO2 molecules, solving the problem of fiber damage while allowing the photocatalytic process to operate efficiently. This allows the capabilities of nanoscale TiO2 to be used on organic based substances such as cotton, polyester, polyamide, viscose and any additional fibers and blends.

In addition, the treatment is very durable, does not consume itself and retains its performance over time.

Perapret AIR is ideal for interior applications such as curtains and textile wall coverings, as well as in automotive interiors, helping to reduce airborne pollutants and airborne odors and improve overall air quality.

Technology is at the heart of Clean Air, a new system that combines Perapret AIR with other recent developments such as Smartrepel Hydro TS for PFC-free durable water repellency and Sanitized T27-22 antimicrobial agent.

Smartrepel Hydro SR is the latest addition to the company’s line of micro-encapsulated, highly biodegradable and PFC-free technologies, providing long-lasting repellency to all cotton and synthetic fibers and their blends.

It has been specially developed for soil repellent finishes to provide advanced protection against water-based stains such as coffee, red wine and ketchup in applications such as home textiles, fabrics upholstery, car seats and interior textiles.

The Smartrepel product line supports the growing adoption of eco-advanced materials and production processes by textile producers and brand owners, meeting standards such as ZDHC, bluesign and Oeko-tex.
