 Full text | Abstract: Poly (lactic acid) (PLA) blends with biodegradable aliphatic polyester of butylene glycol and succinic- and adypic acids (Bionolle) were studied with respect to their usefulness for the preparation of fibrous materials with biodegradability and improved elasticity. The miscibility of PLA/Bionolle blends was investigated by differential scanning calorimetry (DCS) and scanning electron microscopy (SEM). The spinnability of blends was also tested. For the evaluation of the mechanical properties of the blends, testing monofilaments were prepared. The Young’s modulus and elastic recovery of monofilaments were determined. It was found that Bionolle forms with PLA heterogeneous blends. The addition of Bionolle to PLA improves the elasticity of the blends obtained. |
