- Abstract
To improve the filtration properties of polypropylene(PP)melt-blown non-woven material,taking N,N-dimethylacetamide(DMAc)as solvent, the polyurethane(PU)nano fibers were sprayed on the surface of the melt-blown cloth by using the electrospinning process to prepare PP melt-blown/PU electrospun composites.The optimal spinning process parameters were determined through changing the electrostatic spinning solution concentration, spinning static voltage, spinning time and other process parameters.SEM images show that when the spinning solution concentration is 7%, the voltage 20 kV, the receiving distance 20 cm, the extrusion rate 0.020 mL·min-1, the diameter of fiber is finer and the distribution is uniform.Filtration performance test results show that when the concentration of electrospinning is 7%, PP melt-blown/PU electrospinning composite filter effect is higher and the filter resistance is lower, a composite that is best for air filter material.
