Duck feather nonwoven fabrics for textile dying effluent

摘要

In this paper, duck feather fiber was treated by alkaline solution first, then its Cu~(2+) sorption capacity was tested and the sorption mechanism was studied by utilizing infrared spectrum (FTIR) and wide-angle X-ray diffraction (XRD). Moreover, desorption properties of the treated duck feather fiber were investigated in order to exploit it as a recycled industrial effluent treatment material. At last, duck feather fiber was air-laid and thermal-bonded into a kind of composite nonwoven fabric by adding bicomponent low melt PE/PP fiber as binder fiber. It is found that duck feather/bicomponent PE/PP fiber composite nonwoven fabrics show good mechanical properties and Cu~(2+) and Cr~(6+) sorption capacity. It is a promising material for textile dying effluent treatment.
