CIRCULARITY IN REINFORCING TECHNICAL FIBRES TO ENSURE REVALUATION IN TEXTILE INTERMEDIARIES AND TO REUSE NATURAL AND CONVENTIONAL FIBRES TO ADAPT THEM TO CUT FIBRE SPINNING
FIBERSPIN
Motivation
Staple fibre spinning has evolved over time to address environmental challenges. The ability to recycle fibres and the adoption of more sustainable technologies in spinning are contributing to reduce the environmental impact of the textile industry. The business community of the Valencia Region is particularly interested in adapting its processes to the new staple fibre blends as their characteristics make it difficult to reuse conventional parameters, meaning that optimum processability must be studied on a case-by-case basis.
This project focuses on pre- and post-consumer waste, one of the most urgent problems to be solved in the textile industry. Currently, of the tiny percentage of fibres that are recycled, an even more insignificant part of those is recycled through staple fibre technologies. The complex process of fibre preparation and parallelisation has inhibited the use of carding technology.
Objectives
- Improve the processability of new blends and materials used in staple fibre technologies.
- To revaluate post-consumer composites by removing resins with pyrolysis..
- To create nonwoven fabrics from recycled reinforcement fibre with high-performance thermoplastic matrix, achieving more sustainable textiles without losing mechanical properties.
- To develop and produce hybrid yarns and fabrics from recycled reinforcement fibre (rCF) with thermoplastic commodity matrices and high performance thermoplastic matrices.
- To optimise punching and calendering technologies for use in nonwovens of natural fibres and recycled technical fibres.
Value and competitive advantage
-
Improve the quality of recycled carbon yarn.
-
New market opportunities for flax, jute, and pineapple fibers, with potential applications in the composite parts sector.
-
Enhancement of recycled yarn quality and the possibility of expanding materials suitable for textile use.
Obtained results
-
Increase in the percentage of recycled carbon fibers in hybrid yarns made from chopped fibers and thermoplastic filaments. Hybridization with flame-retardant materials, such as PPS, for use in strategic sectors.
-
Revalorization of fiberglass using chopped fiber technologies to create hybrid nonwovens with a high percentage of this fiber.
-
Shaping of thermoplastic composites with hybrid rCF yarns, improving their mechanical properties for applications in load-bearing elements.
-
Spinning of natural fibers with reduced counts using conventional ring and multi-balloon spinning techniques.
-
Revalorization of pre-consumer denim fibers through chopped fiber spinning processes.
