Interlayer fabric and weaving method thereof

The invention discloses a sandwich fabric and a weaving method thereof, and aims to solve the problem of integral weaving of the sandwich fabric, the sandwich fabric comprises a surface layer I, a surface layer II and a core layer, and the core layer is sandwiched between the surface layer I and the surface layer II; the surface layer I and the surface layer II are weft-knitted fabrics and are respectively knitted by yarns I and yarns II, and a plurality of jacquard weaves are formed at corresponding positions of the surface layer I and the surface layer II; at the jacquard weave, the yarn I forms a jacquard loop I woven on the surface layer II, the yarn II forms a jacquard loop II woven on the surface layer I, the surface layer I and the surface layer II are connected, and the middle core layer is clamped between the surface layer I and the surface layer II. According to the invention, through mutual connection of double-sided jacquard weaves, not only are surface jacquard and pattern formation realized, but
