Three-dimensional braided fabric

A three-dimensional braided fabric relates to improvement of the structure of a three-dimensional braided fabric processed by a rectangular braided mode and a circular braided mode. All braided yarns are distributed in a Chinese checkers-like line and row mode with one empty portion in each row in the fabric; the braided yarns are spirally arranged in the longitudinal direction of the fabric; and the braided yarns in arrangement are only intersected with proximate braided yarns on the peripheries of the braided yarns. The three-dimensional braided fabric has the advantages of capabilities of simultaneously decreasing distribution tortuosity of the braided yarns in the braided fabric, improving the use ratio of tensile modulus of the braided yarns, and enhancing damage resistance of the braided fabric when the three-dimensional braided fabric with integral structure is formed. Particularly, the bending degree and the tortuous distribution range of each braided yarn in the braided fabric can be reduced to impro
