A technical feasibility study of an innovative spinning process for recycled carbon fibres

This paper presents a technical feasibility study of a properly modified long-staple spinning process developed at laboratory level for carbon fibres derived from manufacturing scraps or waste and blended with polyester. The study aims to validate the suitability of the new process to produce qualitatively acceptable textile substrates, as well as to detect the effect of the percentage of fibre mixing on the achieved quality of semi-finished products. Visual and laboratory tests indicate that the provided long-staple spinning process allows the production of textile substrates, but only when the carbon fibres are blended with polyester at a defined concertation. Finally, the study suggests that future tests at industrial level are needed to prove the technical feasibility of the proposed spinning process for large-scale production.
