The invention relates to a tissue fiber bracket and a preparation method thereof, in particular to a fiber bracket containing growth factors and a preparation method thereof. The fiber bracket consists of composite fiber material and is manufactured by a coaxial electrospinning spinning device; and the composite fiber material consists of organic polymers with the weight-average molecular weight of 5-500000 and growth factors, and an organic polymer solution and a growth factor solution are mixed and then electrostatically spun to obtain the composite fiber material. The invention has the beneficial effects that the fiber bracket is prepared according to the method disclosed by the invention, the composite fiber material in a nanometer structure is prepared by the coaxial electrostatic spinning method, fiber in a nuclear shell structure can be prepared, the encapsulation rate of electrostatically spun fiber is improved, the initial burst release of the growth factors is slowed down, the bioactivity of the growth factors can be maintained for a long time, the method has a simple process and low cost, is easy to operate, and has wide application prospects in the fields of tissue engineering, wound dressing and the like.
