The invention provides a knitted fabric of a high-strength wear-proof structure. The knitted fabric of the high-strength wear-proof structure is characterized in that that knitted fabric is woven by aramid-fiber-containing fibers, wherein the knitted fabric is of a concave-convex dual-layer structure. In the knitted fabric, the wear-proof performance of the fabric is improved through an aramid fiber material and the dual-layer structure, and the problems that the surface of the fabric is poor in wear-proof performance, and particularly the made fabric for the wrist, the elbow and the knee is poor in wear-proof performance are solved.
