What is denim abrasion and finishing?

There are 1.9 billion jeans sold worldwide each year - and many of them are manufactured to have a vintage look. To get that faded finish, pumice stones were traditionally added to the washing machines in a jeans washing process called stonewashing.

Making one pair of stone-washed jeans requires a lot of water , chemicals and energy. But, with the help of enzymes, stone-washed jeans can be produced more sustainably without the use of stones – this is called enzymatic denim abrasion.

Denim finishing covers various additional processes such as bleaching and resin treatments. Novozymes offers enzymes for more sustainable denim bleaching.

How can enzymes help?

Up until the early 1990s, jeans manufacturers used pumice stone and chemicals to give jeans a stonewashed look. That changed after Novozymes’ scientists developed the first stone-washing enzymes capable of loosening dye from the fabric for a more sustainable wash.

Recently, Novozymes perfected denim abrasion and finishing biotechnology to allow low-temperature enzymes to be sprayed directly on the garment in safety-approved low-water spray machines. This process dramatically reduces water consumption by up to 95 percent.
