Method for manufacturing high-tensile continuous fiber spun yarn using recycled carbon fiber and high-tensile continuous fiber spun yarn

Abstract

An embodiment method for manufacturing a high-tensile continuous fiber spun yarn using a recycled carbon fiber (rCF) includes recovering a rCF raw material from a waste composite material product, the waste composite material product including carbon fiber reinforced plastic (CFRP), fabricating a rCF nonwoven fabric using the recovered rCF raw material, producing slitter yarns cut into a long length and a predetermined narrow width by placing the rCF nonwoven fabric into slitter equipment in a slitting process, fabricating the high-tensile continuous fiber spun yarn with a predetermined thickness by twisting at least one of the slitter yarns through twisting equipment in a twisting process, and producing a spun yarn product by winding the high-tensile continuous fiber spun yarn on a bobbin using a spinning machine.
