摘要： Blue-colored bioabsorbable surgical fibers are obtained by adding and dispersing a bioabsorbable polymer, which is selected from polyglycolic acid, poly(ℓ-lactic acid) and glycolic acid-ℓ-lactic acid copolymers all of which are useful as surgical fibers, and indigo in a non-aqueous organic solvent having low solubility for the polymer and indigo, heating the resultant dispersion at a temperature below l20°C to distill off the solvent, thereby to obtain a master batch with the indigo incorporated therein at a high concentration, mixing and kneading the master batch with a fresh supply of the polymer, and then spinning the resultant polymer mixture.
