Nano Bubble Technology: A New Way to Sustainable Jeans Finishing

Authors: Elias Khalil

A new technology based on nano bubbles developed and patented by a Spanish company, Jeanologia, is known as e-flow. The e-flow ‘breaks up’ the surface of the garment, achieving soft hand feel and controlling shrinkage. A minimal quantity of water is needed and there is zero discharge from the process. Air from the atmosphere is introduced into an electro flow reactor and subjected to an electromechanical shock creating nano bubbles and a flow of wet air. The nano bubble mix is then transported into a rotating tumbler containing the denim garments, and when it comes into contact with them produces a soft and natural hand feel. The garments are then dried in the same tumbler. When treating indigo dyed garments with this technology, some indigo cross contamination may occur that can be eliminated by a dry ozone treatment.
