Innovative Washing Process for Jeans to Cut Water Usage

The Fast Retailing Group has developed a new washing process for jeans that reduces water usage by up to 99%, with an average of more than 90%*1. The technology was originated at the FR Jeans Innovation Center, the Group's facility for jeans research and development in Los Angeles, California, and has been adopted from the 2018 fall/winter season's UNIQLO Men's Regular Fit Jeans and J BRAND Sustainable Capsule Collection. In 2019 a total of 10 million pairs of jeans from the two brands, the equivalent of almost one-third of FR's annual production quantity, will be manufactured with this process. By 2020 the new technology will be used for all jeans made and sold by the Group.
The latest innovation combines advanced washing equipment utilizing nanobubbles and ozone with the skills of expert jeans designers, to greatly reduce the amount of water in the washing process compared to conventional production methods, while still ensuring high quality and design. By incorporating this technique, UNIQLO successfully reduced the amount of water used in the washing process of its Men's Regular Fit Jeans by up to 99%, with an average of more than 90%.

During 2020 the Group plans to manufacture 40 million pairs of jeans with the new washing process, expecting to reduce approximately 3.7 billion liters of water, an amount large enough to fill around 1,500 international regulation swimming pools*2.
In addition, the pumice typically used in the washing process has been replaced with artificial stone that can be used semi-permanently, helping to reduce water pollution. The burden on workers has also been lightened with the introduction of lasers to replace the labor-intensive scraping process that has traditionally been done by hand.
