Jeanologia's new laser solution replaces the use of potassium permanganate in jeans production

Spanish technology firm Jeanologia is launching a new laser solution that replaces the use of potassium permanganate in the jeans production process.

The company says its new Light PP Spray solution eliminates the chemical solution still used by 2m workers worldwide to bleach and brighten denim for a worn effect. Potassium permanganate is a very strong oxidising agent that is a deep violet in colour and can can reduce indigo and sulphur dyes to colourless.

Launched at this week's Denim By Première Vision trade fair in Barcelona, Jeanologia explains it has now managed to find alternative laser-based techniques to all jeans finishing processes that are harmful to both workers and environment, including sandblasting, stonewashing and manual scraping.

It argues the PP spray-gun process is the most dangerous for the health and safety of workers since it transforms chemicals into micro-particles that can lead to lung problems for workers.

The elimination of potassium permanganate spray by the use of laser "is a milestone for the textile industry because it transforms the process of jeans production in the world," according to Jeanologia CEO Enrique Silla. "We've managed to replace all hazardous technology techniques for workers and emissions of the textile industry that, in the last four years have been reduced to 0%."

Light PP Spray will be used exclusively for a year by 200 Jeanologia partners in 47 countries, who between then account for 40% of world denim production.
