| titleOfInvention | Preparation method of collagen fiber |
| abstract | The invention discloses a preparation method of collagen fibers, and belongs to the fields of tissue engineering and regenerative medicine. The invention takes animal collagen as raw material, prepares collagen solution by dissolving with ionic liquid, then coagulates the collagen solution in an organic coagulation bath by a wet spinning device to assemble collagen fiber with a three-strand spiral structure, the collagen fiber can be wound and continuously broken after being spun by the spinning device, and the continuous collagen silk thread which is not adhered to each other is obtained. The collagen fiber prepared by the method is not subjected to any chemical crosslinking treatment to obtain the type I collagen fiber, the collagen has good nutrition and repair functions, and the collagen can effectively repair the damaged cells of the wound in the decomposition and absorption process after being implanted into a human body, so that the tissue structure of the wound is recovered to the preoperative state as far as possible. The product can be used for skin suture or skin shaping and caring with flat wound surface and no scar left. |
