Abstract
The present invention relates to the technical field of silk scaffolds, and in particular, to a silk/pet mix-woven scaffold and a preparation method and use thereof. The silk/PET mix-woven scaffold is formed by weaving silk and PET fibers. Sericin of the silk is removed. The silk and the PET fibers are mixed and knitted. The PET fibers provide reliable fixation in an early stage to maintain the stability of mechanical properties, and the silk degrades gradually in a later stage to promote the growth of new tissues to achieve the integration of the scaffold and the body. When the scaffold is used for artificial tendon/ligament recovery, its overall performance is better than that of pure silk or pure PET fiber scaffolds, and the scaffold has excellent clinical transformation potential.
