A significant minority equity investment from John Hogg Technical Solutions will now support the spinout’s industrial validation in working mill environments.

SwitchDye, a University of Leeds spinout, has secured investment from John Hogg Technical Solutions to scale its eco-friendly polyester dyeing technology.
Using a fizzy water-based system, it cuts chemical use, water consumption, and energy needs.
It will support real-world mill validation and commercialisation, aiming to reduce textile pollution and enable more circular manufacturing.

John Hogg will provide technical input, manufacturing and stewardship expertise, along with access to customer networks to help SwitchDye move from lab to mill at pace.

“SwitchDye’s pioneering approach to polyester dyeing will help to drive a more circular and sustainable textile industry,” said professor Nick Plant, University of Leeds.

Polyester makes up more than half of all global fibre output. Dyeing fibre is highly energy intensive and consumes 600 billion litres of water every year across the globe, the university said in a press release.

Textile production is estimated to be responsible for about 20 per cent of global clean water pollution, and polyester dyeing alone releases around 280,000 tonnes of waste dye and other chemicals annually.

“SwitchDye’s pioneering approach to polyester dyeing will help to drive a more circular and sustainable textile industry. This is another example of the outstanding talent that exists within our research community and our strength in nurturing and supporting innovation in new technologies,” explained Plant.

Born from an ongoing collaboration between the Schools of Design and Chemistry at Leeds, SwitchDye’s team includes researchers and co-founders Dr Nathaniel Crompton, Dr Harrison Oates, professor Richard Blackburn and professor Chris Rayner.

The new dyes were synthesised in the Wolfson CO2 laboratory in the School of Chemistry and then transferred to the facilities at the University’s School of Design and the Leeds Institute of Textiles and Colour (LITAC), where the team conducted rigorous tests to demonstrate how SwitchDye’s system can remove additives that typically account for up to 90 per cent of chemicals, without compromising performance.

The technology is designed as a drop-in for common dyehouse equipment, allowing mills to keep using their existing machinery.

In addition to the chemical savings and reduction in waste, the new dyeing system can also streamline operations by reducing rinse stages and shortening machine time, using 40 per cent less water and saving on energy. The dyes can also be removed more easily at the end of products’ life, supporting fibre-to-fibre recycling.

The university’s commercialisation team worked alongside SwitchDye to make investor introductions and provided funding to help the team achieve commercial validation.

“Partnering with John Hogg gives us the technical expertise and industry reach to move from lab success into consistent, real-world application. Over the coming months, we’ll be working closely with dyehouses and brands to demonstrate how the technology integrates into existing equipment and delivers measurable savings,” Dr Harrison Oates, chief technology officer at SwitchDye, said.

“The partnership with SwitchDye marks the start of an inspiring journey with the potential to improve the future of textile manufacturing for many years to come. At John Hogg, we have always taken pride in understanding our customers’ needs and the evolving demands of the market. Being part of an innovation that delivers a true step forward in sustainable dyeing technology is something we are genuinely excited about. We also see clear alignment between our businesses, with John Hogg’s wider capabilities helping to accelerate SwitchDye’s path to commercialisation,” Sam Walton, chief technical officer at John Hogg, said.
