The present invention provides a braided hernia patch for preventing adhesion and promoting repair and a preparation method thereof. First, polytetrafluoroethylene filaments are uniformly wrapped on the surface of high-strength core yarns to obtain core-shell composite yarns, and then the core-shell composite yarns and high-strength yarns are woven into a double-sided structural fabric in a weaving manner to obtain a mesh fabric with high-strength yarns on one side and core-shell composite yarns on the other side; finally, the mesh fabric is subjected to low-temperature pressure plastic film forming treatment to obtain a braided hernia patch. The present invention adopts core-shell composite yarns in combination with weaving molding and low-temperature pressure plastic film forming processes to obtain a braided hernia patch with a sparse high-strength mesh structure on one side and a dense polytetrafluoroethylene mesh film structure on the other side, realizing the integration of anti-adhesion and support functions; the braided hernia patch solves the problems of mismatch between the mechanical and biomedical properties of existing hernia patches and poor application performance, and has the softness, bending tolerance and foldability required for the patch, and has broad market application prospects.
