Novel nanofiberous membrane fabricated via electrospinning of wastage fuzzes of mechanized carpet used for dye removal of the carpet dyeing wastewater

Abstract

Novel nanofibrous membrane was fabricated by using electrospinning of wastage fuzzes of mechanized carpet which was used to remove the dye of the textile wastewater. SEM images showed that nanofibers with average diameters of 200 nm were successfully fabricated by electrospinning technique. The physicochemical properties of electrospun nanofiberous membranes were studied by differential scanning calorimetry (DSC), energy-dispersive X-ray (EDX), and Fourier transform infrared (FTIR) spectroscopy. FTIR confirmed the presence of C N, C N, and C N groups in the electrospun nanofibers which are the main functional groups of polyacrilonitrile (PAN). The resulting membrane showed dye retention of 96% of carpet dyeing wastewater, demonstrating the high separation potential of such membrane for wastewater treatment. We believe that simple approaches such as the present one would open up enormous possibilities in effective uses of wastage fuzzes of textile industry, considering the fact that electrospinning is a cost-effective method for the mass scale production of nanofibers.
