STUDY ON THE RELATIONSHIP BETWEEN STRUCTURE PARAMETERS AND FILTRATION PERFORMANCE OF POLYPROPYLENE MELTBLOWN NONWOVENS

Original language description

In this study, polypropylene meltblown nonwoven fabrics with different structure parameters such as fi ber diameter, pore size, and areal density were prepared by the industrial production line. The morphology of meltblown nonwoven fi bers was evaluated by using scanning electron microscope, and the diameter of fi bers was analyzed by using image-pro plus software from at least 200 measurements. The pore size of nonwoven fabric was characterized by a CFP-1500AE type pore size analyzer. The fi ltration effi ciency and pressure drop were evaluated by TSI8130 automatic fi lter. The results showed that the pressure drop of nonwoven fabrics decreased with the increase in pore size; the fi ltration effi ciency and the pressure drop had a positive correlation with the areal density. However, when the areal density is in the range of 27–29 g/m2, both fi ltration effi ciency and pressure drop decreased with the increase of areal density; when the areal density was kept constant, the fi ltration effi ciency decreased as the pore size decreased; when the pore size of the meltblown nonwoven fabric is less than 17 μm, the fi ltration effi ciency increased as the pore diameter decreased; when the pore diameter of the nonwoven fabric is larger than 17 μm. In a wide range, the pressure drop decreased as the fi ber diameter decreased.
