Fibre52’s cotton Prepare for Dye (PFD) and dye biochemistries have been certified by Zero Discharge of Hazardous Chemicals (ZDHC) and are now on the ZDHC list of approved chemistries.

Fibre52 says its ZDHC certification means mills and brands around the world now have a sustainable alternative to the traditional PFD and dye processes that use harsh chemicals, high heat and vast amounts of water.

Fibre52 describes itself as an environmentally safe process that prepares cotton for a so-called perfect dye job without harsh chemicals. It explains this is especially important for brands and mills that require ZDHC validation in order to comply with government regulations related to the chemistries they use and validation of their sustainability claims.

Plus, the brand claims Fibre52 produces a superior cotton product, while using up to 70% less water and up to 40% less energy.

Fibre52 president Laura Thornquist says: “We aim to be an industry leader by offering a net-neutral, bio-friendly chemistry that’s combined with an easy-to-adopt process for preparing and dyeing cotton.

“By aligning our practices with ZDHC’s guidelines, Fibre52 is playing a role in reshaping the global textile and fashion industry toward greater sustainability.”

Fibre52 explains achieving certification involved testing its chemistries to the ToxFMD Screened Chemistry standards required by ZDHC. This included the testing of both products and residuals to prove that Fibre52’s chemistries are non-toxic, environmentally safe and fully comply with ZDHC guidelines.

During May's Texprocess Americas 2023 and Techtextil North America 2023 event Thornquist told Just Style: “We’re working with blends and showing the world that there is a cotton that can rival synthetics. We can also tackle wool and cashmere and move into insolubles.”
