The present invention belongs to the rack material preparing technology in tissue engineering. Polyglycollide, polylactide or their mixture copolymer fatty polyester fiber material is woven into rope-like 3D myotendinous rack material and there is chitosan, chitin or glutin of 0-30% in the fiber. The fatty polyester fiber has circular, ring or opened C-shaped cross section and the specially shaped C-shaped fiber accounts for 0-20%. It has the advantages of high tension strength, controllable degrading speed and good cell affinity. |
