Promethean Particles partner in water repellent fabrics project

The highest level of water and oil repellency is currently achieved by using highly fluorinated chemical substances, but increased concern and heightened regulation of perfluorocarbons and polyfluoroalkyl substances (PFCs and PFASs) is leading the textile industry to seek alternative chemistries.

The partners involved in the REPETEX project are North West Textiles Network, Manchester Manufacturing Group, Mexar, an independent inkjet ink manufacturer specialising in water-based inkjet technologies, and The Welding Institute (TWI).

In a statement, Dr Selina Ambrose, Technical Manager at Nottingham-based Promethean Particles, said: “Durable water repellent technologies have been traditionally incorporated into technical textiles for Personal Protective Equipment (PPE) applications, utilised by first responders, military personnel and outdoor industrial workers.

“More recently, there has also been a trend for water repellent apparel within high-end fashion, sports and leisurewear markets. As demand for such fabrics increases, it has become necessary to find a manufacturing solution that is greener and safer yet doesn’t comprise the other key functionalities of these high-performance textiles including durability, comfort and breathability.”
