Tonello, global specialist in garment finishing technologies, will launch their latest advance in denim manufacturing, the NoStone, a new system developed in collaboration with Levi Strauss & Co ( This special finishing technique can age denim exactly like stone washing, though without employing chemicals nor pumice stones.

The NoStone system will be presented within ITMA, specialized textile machine trade show to be held in Milan Rho-Pero from 12 to 19 November, 2015. The newborn process eliminates the use of pumice stones, replacing them with a stainless-steel abrasive drum, fastened to the washing machine. This drum can create a variety of finishes through flexible abrasion adjustments to create the look and style varieties consumers love. Due to the mechanical – rather than chemical – nature of the process, the NoStone effect is the same as that of stone-wash and reduces the carbon footprint created by using pumice stones.

NoStone was developed to be applied in all Tonello machines and maintains the same load capacity, enabling easy adoption throughout denim manufacturing facilities. The lining can easily be removed, so the machine can also run normal washing and dyeing processes.

Tonello expects the NoStone process will reduce water consumption, production costs, carbon footprint, processing time and manual labor. The new process eliminates the dust and sludge generated from stones, it doesn’t damage the machine as pumice stones do, and it creates desired finish effects in both sampling and production machines.

The NoStone innovation is a good and exciting example of how two iconic companies – Levi Strauss & Co., and Tonello, can collaborate in a way that brings sustainable technology “to the industry,” commented Bart Sights, senior director of technical innovation, Levi Strauss & Co. “This will be a win for our two companies, but also for the industry as a whole. And perhaps, most important for the environment.”

Starting in January 2013, the Tonello Research Center launched their studies for developing this new alternative to stone-washing. Tonello partnered with Levi Strauss & Co. in order to develop and test the NoStone wash technique in real production situations.

This technology will be among finalists of the ITMA Sustainable Awards, whose award ceremony giving will happen on 12 November 2015, opening day of the show.
