During Techtextil in Frankfurt/Germany, Archroma Management GmbH, Pratteln/Switzerland, launched a new light-activated air purification technology for all kinds of fabrics and also a PCF-free technology for durable water-based soil repellence.
The mineral based Perapret Air liq eliminates air pollutants and airborne smells by imitating the natural process of photocatalysis under normal day and artificial light sources. The chemistry usually used in such applications is nano sized TiO2 (dioxide titanium), which attack every organic matter, including the textile fiber, and not only pollutants.
Perapret Air liq is produced using a unique and patented Core Shell technology that partially surrounds the TiO2 molecules, solving the issue of fiber damage, and at the same time still allowing the photocatalytic process to work efficiently.
Therefore, the innovative Core Shell technology behind Perapret Air liq makes it possible to use the capabilities of nano sized TiO2 also on organic based substances such as cotton, polyester, polyamide, viscose and any additional fiber and its blends.
In addition, the treatment is highly durable, as the product does not self-consume and retains its performance over time.
Perapret Air liq is ideally suited for indoor applications, such as curtains, textile wall coverings, as well as cars and other automotive interiors, allowing to reduce air pollutants and airborne smells and thus improving overall air quality*.
The technology is at the core of Clean Air, a new system that combines Perapret Air liq with other recent innovations such as Smartrepel Hydro TS liq for PFC-free durable water repellence, and Sanitized T27-22 liq antimicrobial agent.

Smartrepel Hydro SR liq is the latest addition to a range of micro-encapsulated, highly biodegradable, non-PFC based technology offering exceptional, durable water repellency to all cotton and synthetic fibers, and their blends.
The new Smartrepel Hydro SR liq has been specifically developed for soil repellent finishes aiming to offer industry-leading protection against water-based stains such as coffee, red wine and ketchup, in applications such as home textiles, table clothes upholstery, car seats and interior textiles.
The new grade offers the signature Smartrepel high performance standard: a good symbiosis of water protection, soil repellence, breathability and durability – with the soft hand-feel that is sought after by consumers.
The Smartrepel product range supports the increasing adoption of eco-advanced materials and production processes by textile producers and brand owners adhering to standards such as ZDHC, bluesign and Oeko-tex.
These innovations have been developed in line with the principles of “The Archroma Way to a Sustainable World: safe, efficient, enhanced, it’s our nature”.
