The invention provides a composite fabric for making suitcases and bags and a processing technology of the composite fabric, and belongs to the field of light industry textiles. The invention solves the problem that an existing fabric has a poor ventilation effect. The composite fabric for making the suitcases and bags comprises a body formed by laminating a PVC film and a skeleton fabric layer, wherein the body is densely covered with through holes which are in the shape of straight holes, the extending directions of axes of the through holes are consistent with distribution directions of the PVC film and the skeleton fabric layer, and the pore size of the through holes is 0.6-1.8mm; the processing technology consists of a PVC film calendering process and a lamination process, wherein the PVC film calendering process comprises the steps of A, measurement, B, stirring mixing, C, internal mixing, D, continuous plasticization with two rolling wheels, E, filtration, F, four-roll calendering, G, sub-surface embossing, H, cooling shaping, and I, coiling; the lamination process comprises the following steps of: J, high-temperature lamination, K, cooling shaping and edge cutting, L, through hole forming, and M, furling. The composite fabric for making the suitcases and bag and the processing technology of the composite fabric have the advantage that the ventilation effect of the composite fabric can be improved.
