Regarding dyeing and finishing processes, historically, a range of substances with very high contaminating potential have been used, generating wastewater with a significant impact on the environment and on the safety and health of individuals. Therefore, it is evident that this is a critical point for the sector in reducing the aforementioned carbon footprint.

As a solution to this issue, a new technological solution was designed and patented (No. P202130437) that is capable of moving, dyeing, and finishing fabric in rope form using a nebulization process for Jet-type dyeing machinery, without the presence of a traditional dye bath.

In the case of spinning, efforts have focused on optimizing conventional ring spinning. Ring spinning technology is one of the options for processing slivers and transforming them into yarn. Using a system of belts, it applies friction to the sliver while stretching it, allowing control over the final yarn count. Once the twist is applied, the yarn passes through a cursor located at the bottom, acting as a tensioner and applying the necessary winding tension. Depending on the tools used, the machine can work with either short or long fibers.

AITEX, in collaboration with the company that owns the multiball patent, has tested and validated this multiball technology for obtaining technical yarns from complex fibers using the twisting technology. The application of double-twist ring spinning technology has resulted in several advantages compared to conventional twisting: increased production and efficiency.

The third area addressed by the project is the recycling of post-consumer waste. The solution is based on a valorization strategy that seeks to provide a tangible second life to these wastes while opening the door to business opportunities in sectors such as interior design, decoration, and contract fields, among others.

The proposed solution is based on a mechanical valorization pathway that incorporates processes known as mechanical shredding, as well as new composite forming technologies, such as the innovative glue-blender technology and compression molding. The glue-blender technology allows for the mixing of textile waste with a thermosetting resin. Subsequently, these impregnated textile fibers are introduced into a compression molding machine, where temperature and pressure induce curing of the matrix element, its consolidation, and thus the formation of the polymer-particle composite.

As a fourth line of work, traceability in the supply chain is addressed. This task is presented as a fundamental element to ensure transparency, quality, efficiency, and responsibility in the flow of products from their origin to their final destination. Some key reasons for the importance of traceability in the supply chain include product quality and safety, inventory and stock management, operational efficiency, regulatory and legal compliance, accountability and sustainability, improved relationships with suppliers, and cost optimization.
