NOVELTY - The invention relates to the field of chemical fibre, especially relates to a graphene composite fibre and composite fibre processing device. wherein one graphene composite fibre comprises a graphene-chinlon central layer and a chinlon outer interlayer coated outside the graphene-chinlon central layer; the graphene-chinlon central layer is hollow cylindrical; and the graphene-chinlon central layer is provided with a straight slot along the axial direction on the side wall; through the graphene-chinlon central layer and chinlon outer interlayer interaction, the whole structure is adhered more tightly; the graphene material can improve the antibacterial effect of the silk thread, and the silk thread has far infrared property and negative ion releasing ability, so it has good health care effect. In addition, a composite fibre processing device comprises an upper material part, a melting and soaking part, a cooling part and a material receiving part; the cooling part passes through the cooling cylinder and the cooling pipe; the to-be-processed fibre is cooled from the inner and outer two sides; it is good for further improving the cooling effect and reducing the filament breakage rate.
