Manufacturing method of denim composite fabric

The invention relates to the technical field of composite fabrics, and discloses a denim composite fabric manufacturing method, which comprises: S1, preparing raw materials; s2, pretreatment: pretreating the denim; s3, processing the raw materials; s4, composite processing: stacking the denim and the composite material together, and bonding the denim and the composite material together in a hot pressing manner; s5, subsequent finishing: finishing the denim composite fabric; s6, inspection: inspecting the prepared composite fabric; s7, packaging: packaging the composite fabric; according to the invention, auxiliaries including phosphate ester, amino silicon oil, polyvinyl alcohol and graphene oxide are added to the base cloth layer, and the phosphate ester improves the flame retardant property; the amino silicon oil improves the hydrophilicity of the fabric; the polyvinyl alcohol improves the strength of the fabric; the graphene oxide has certain antibacterial performance, antistatic effect or conductive effec
