Described herein is a weft-knitted spacer fabric and a preparation method thereof, a polyurethane foam composite material including the fabric, a preparation method of the composite material and its use in shoe materials. The weft-knitted spacer fabric consists of an upper surface layer, intermediate spacer yarns, and a lower surface layer, and the upper surface and the lower surface layer are connected by the tuck of the spacer yarns in the upper surface and the lower surface layer to form a three-dimensional structure in an integrated manner. The different selected tuck needle changes the connecting distance and the number of connections of the tuck, and the thickness of the spacer fabric and the arrangement density of the spacer yarns are changed by the action of the upper and lower surface layers of elastic yarns.

Weft-knitted spacer fabric and a preparation method thereof, use of the fabric for the preparation of a composite material and a composite material comprising the same
