The invention discloses a lumbering protection clothing lining cloth and a preparation process thereof. The lumbering protection clothing lining cloth is composed of warp yarns, weft yarns a, weft yarns b, binding silk a and binding silk b; the weft yarns a and the weft yarns b are evenly arrayed and interwoven with the warp yarns, wherein the arrangement ratio of the weft yarns a to the weft yarns b is 1:1; the binding silk a and the binding silk b are wound around the outer surfaces of the warp yarns, the weft yarns a and the weft yarns b through a specific yarn padding process. The processhas the advantages that compared with existing lumbering protection clothing lining cloths, the lumbering protection clothing lining cloth is characterized in that instead of adopting one kind of weftyarns as the raw materials, two kinds of weft yarns are adopted as the raw materials for interweaving, the specific warp yarns, the weft yarns a, the weft yarns b, the binding silk a and the bindingsilk b are selected as the raw materials, the weight of the lumbering protection clothing lining cloth can be effectively reduced through the specific yarn padding process, and the protection effect of the lumbering protection clothing lining cloth is effectively ensured.
