Fiber fabric and blade of wind turbine with the same

A fiber fabric, comprising:

• a plurality of main-direction fibers, arranged evenly and in parallel along a zero-degree-direction of the fiber fabric;
• a plurality of weft fibers, each of the weft fibers arranged to have an included angle with each of the main-direction fibers;
• and
• a plurality of braided threads arranged along the zero-degree-direction of the fiber fabric and parallel to each other, wherein:
• the plurality of main-direction fibers and the plurality of weft fibers are stitched together by the plurality of braided threads to form a plurality of fabric layers;
• the plurality of braided threads include first braided threads arranged along an extension direction of the fiber fabric, each of the first braided threads having a color different from a color of any of the main-direction fibers and the weft fibers, and a respective distance between any two adjacent braided threads of the first braided threads is configured to make wrinkle defects formed in the plurality of fabric layers detectable;
• and
• the first braided threads are configured to allow determination of any wrinkle defect having been formed in the fiber fabric and positions of the wrinkle defect by visual observation of contours of the first braided threads.
