A stitched double layer composite hose is provided. The stitched double layer composite hose includes a middle fabric pipe layer, an inner surface composite colloid material layer and an outer surface composite colloid material layer. The structure of the fabric pipe layer is weft-stitched double-layer unit structure. The double-layer unit structure includes an outer layer, an inner layer and stitched wefts. The inner layer includes inner layer warps and inner layer wefts; the outer layer includes outer layer warps and outer layer wefts. The stitched wefts interweave with the outer layer warps and the inner layer warps for conjoining the inner layer and the outer layer together. The fabric pipe layer weaved solves problems of the stitched double layer composite hose in the fabric pipe layer of traditional casing, with such advantages as high flexibility, less weaving point, less loss of yarn strength and less degree of torsion.
