31 Dec COLORNOU FINISHES AN R&D PROJECT FOR THE DEVELOPMENT OF A RAW YARN CONE DYEING PROCESS
At COLORNOU, S.A. we are experts in the integral management of yarn dyeing for the textile industry, providing the desired color and presentation to the yarn. Colornou is quality of product and service, it is research and innovation and therefore evolution. All this is what allows us to grow day by day and offer our customers a great series of possibilities with a product of the highest quality.
Our innovative character is one of the highlights. R&D is essential for Colornou. In this sense, in December 2020, the TINTE-REC project that began in June 2019 (IDI-20190790) for the development of a cone dyeing process of raw yarns of recycled origin, and which was financed by the CDTI, came to an end and co-financed by the European Regional Development Fund (ERDF), through the Pluri-regional Operational Program for Smart Growth 2014-2020.
The objective of the project has been the development of a cone dyeing process for raw yarns of recycled origin, on recycled polyester yarns (rPES), made from post-consumer materials, and recycled cotton (rCO), from its majority of industrial waste, maintaining a high level of quality, reliability and reproducibility
The project is strategic for Colornou since, in view of the already consolidated trend of the textile markets towards recovery fibers, it makes us a pioneer in the dyeing of raw yarns of recycled origin. Until the present project, it was very problematic to dye regenerated fiber yarns, since the fiber did not present homogeneous characteristics, its dyeing gave rise to irregularities in the cones and in the different dyes, which have to be corrected by reoperating them, which makes it more expensive. to make the dyeing of raw recovery yarns unfeasible.
Against this, the novelty of this project lies in the realization of a highly controlled cone dyeing process on recycled yarns with a new dyeing system. This achieved objective represents an innovation at a national and international level, since until now the color of the recycled yarns is given according to the materials to be recycled or the dye added to it during the recycling process, not finding yarns where the color has been a posteriori by applying colorants by dyeing process.
