text: "This study presents a sustainable and non-destructive recycling strategy
for synthetic fibres, specifically polyethylene terephthalate (PET), polyamide
6 (PA6), polyamide 66 (PA66), and elastane (EL). Two deep eutectic solvents (DESs)
were synthesised, enabling selective dissolution of EL without degrading the surrounding
polymer matrices. The dissolved EL phase was subsequently recovered by centrifugation,
demonstrating its potential for material reuse. Comprehensive characterisation
confirmed that the process preserves fibre integrity. SEM imaging revealed no
detectable changes in fibre morphology, while DSC and TGA analyses indicated that
the thermal properties of both EL and synthetic polymers were preserved. ATR-FTIR
spectroscopy verified the absence of measurable chemical modifications. Mechanical
testing showed that solvent treatment did not compromise the tensile performance
of PET, PA6, or PA66 fibres, confirming their suitability for fibre-to-fibre recycling.\r\nThe
recovered fibres were successfully re-extruded into continuous filaments, confirming
their melt processability and enabling potential applications in textile yarns,
technical fibres, nonwovens, and polymer components via melt-spinning or moulding.
These results demonstrate that the proposed DES-based method offers a promising
approach for the circular recycling of complex fibre blends and provides a viable
pathway towards industrial implementation."

text: Global fibre production has expanded rapidly, with polyester and cotton dominating,
significantly contributing to textile waste and increasing demand for sustainable
solutions. This study presents innovative method to recycle polyester/cotton (PET/CO)
blends using hydrophobic deep eutectic solvents (DESs), eliminating the need for
toxic chemicals while achieving high dissolution yields. PET was completely dissolved
within 5 min, substantially outperforming state-of-the-art methods and facilitating
the efficient and selective recovery of both components, PET (97%) and CO (100%).
SEM imaging confirmed no morphological changes in cotton fibres after treatment.
The thermal stability of the recovered materials was validated using DSC and TGA
analyses, while ATR-FTIR spectroscopy indicated no chemical changes. Mechanical
testing confirmed recovered cotton’s tenacity and elongation are within expected
ranges despite showing a decrease of 28% in tenacity and 34% in elongation. Hence,
the proposed process provides an efficient and sustainable recycling solution
for PET/CO blends, retaining both polymers in a condition similar to virgin materials
used in textile manufacturing with minimal processing time.
