The Study of Recycled Poly(Ethylene Terephthalate) Nanofibres from Pet Bottle

Bottles made from poly (ethylene terephthalate) (PET) can be recycled and reused the material to reduce the amount of waste going into landfills. In this study, electrospun fibres from recycled PET were produced by a melt-electrospinning method. The effect of the melting temperature, applied voltage and distance between die and collector on the morphology of the electrospun fibres was investigated. Thermal properties of recycled PET were characterized by a differential scanning calorimetry (DSC) and a thermo gravimetric analysis (TGA). It was observed that recycled PET granules were melted at a temperature of 260, 290 and 310 °C, the melt polymer was electrospun at a high voltage of 38 kV and electrospinning was carried out at a distance of 12 cm. The Recycled PET electrospun had diameters ranging from 45 to 65 µm.
