ヒーター加熱とレーザー照射加熱の併用によるポリL乳酸 / ε-カプロラクトン共重合体モノフィラメントの延伸 Drawing of Poly (L-lactide-co-ε-caprolactone) Monofilament under the Heating of Air-heater and/or Laser Irradiation

Poly (L-lactide-co-ε-caprolactone) monofilament was drawn with three ways of heating methods, those are air heater heating, CO<sub>2</sub> laser irradiation, and laser irradiation after heater pre-heating. The mechanical properties and diameter deviation of the drawn filaments were analyzed. The lowest drawing stress and the least diameter deviation were obtained for the heating of laser irradiation after heater pre-heating. Moreover, only by the heating of laser irradiation after heater pre-heating, the drawing point could be fixed even for draw ratio of 4. And after the 3-step drawing, the filament which have the maximum strength of 651MPa was obtained by the heating method.
