The invention discloses a non-solvent-residue composite sofa fabric production process. The process includes the following steps of firstly, selecting non-solvent resin PUR hot melt glue for use, melting the non-solvent resin PUR hot melt glue through a glue melting plate at the high temperature of 130 DEG C, guiding the liquid non-solvent resin PUR hot melt glue into a glue applying roller, stabilizing the liquid state of the non-solvent resin PUR hot melt glue by the glue applying roller through the constant temperature of 110 DEG C, and uniformly transferring glue onto a surface fabric anda bottom fabric of a required composite fabric for adhesion by means of the 28-mesh depth mesh-shaped glue applying roller. By means of the process, no solvent is used, it is ensured that the fabric is free of solvent residues, VOC emission can be controlled by means of the hot melt glue composite sofa fabric, waste gas treatment cost is saved, a safe and environmentally-friendly production environment is provided for wor
