Sandblasting jeans seems to be the cool thing to do nowadays. I’m not big on fashion so this is all strange to me. Well, as you can probably imagine sandblasting denim is not good for the environment so some smart people have figured out a better way to blast your jeans.
Blue denim jeans are one of the most popular and iconic fashion items in the world; now a study published in Biotechnology Journal reveals a cheaper, more efficient and eco-friendly method for treating dyed denim. The process of â€˜surface activationâ€™ used to wash-down the denim following dyeing could also offer an alternative to the dangerous, and internationally banned, sandblasting technique.
â€œThe global production of denim is estimated at 3 billion linear meters and more than 4 billion garments per year,â€ said Thomas Bechtold, from the Research Institute for Textile Chemistry and Textile Physics at the University of Innsbruck. â€œTo create blue jeans denim is dyed with indigo an organic compound which is estimated to be produced in quantities of over 30.000 tons per year.â€
I still don’t get why we need sand in our jeans.
