Ten Cate, which specialises in protective and lightweight material production, already works with Xaar on inkjet technology for the textile market.
Xaar, which bought into Xennia in September 2005, will enjoy a collaborative relationship with both companies on the EU-subsidised Digitex project.
This project covers the development of digital textile finishing to enable functional characteristics, such as fire resistance and self-cleaning properties, to be applied to fabrics.
Digitex, which was announced in 2006, has a total project budget of £9.47m (€12.7m), £5.1m of which is EU-subsidised.
Xaar chief executive Ian Dinwoodie said Xennia "had strengthened its position for the future through what is an innovative and collaborative agreement with Ten Cate".
"We already work with Ten Cate under an EU Framework project and we look forward to working more closely with them in the future and to establishing inkjet as a key production process for the textile and specialist materials market."
