Fiber fabric reinforcing material with humidity display function and preparation method and device for fiber fabric reinforcing material

The invention discloses a fiber fabric reinforcing material with a humidity display function and a preparation method and device for the fiber fabric reinforcing material. According to the method, continuous production is achieved through a conveying device, an infiltrating device and a drying device. A humidity indicator solution is arranged in the infiltrating device. The method specifically comprises the following steps of: step 1, conveying a raw material fiber yarn bundle to the infiltrating device through the conveying device, and infiltrating the raw material fiber yarn bundle with the humidity indicator solution; step 2, conveying the infiltrated fiber yarn bundle to the drying device through the conveying device for drying; and step 3, weaving the dried fiber yarn bundle to form the fiber fabric reinforcing material with the humidity display function. The method can achieve continuous preparation of the fiber fabric reinforcing material and is simple and convenient. By using the method, the water con
