Realfio transforms colour into identity. By combining technology, experience, and creativity, we develop customised colour solutions for sewing threads.

More than producing high-quality industrial sewing threads, Realfio specialises in creating colours that precisely meet each client’s needs.

Colours play a fundamental role in the success of any project, and Realfio ensures accuracy and excellence in every shade it produces.

With years of experience and a continuous investment in advanced technology, Realfio is the ideal choice for those seeking consistent results of superior quality.

In addition to a wide range of colours permanently available in stock, Realfio offers the possibility to develop custom colours (through lab dips or colour systems such as Pantone), creating the exact shade each client needs to stand out in the market.

Realfio’s dyehouse is equipped to dye all types of fibres, whether natural or synthetic. Furthermore, it has a sophisticated laboratory capable of creating and adjusting colours for any type of thread, providing fast and straightforward information.
