Abstract

In order to study the influence of gradient structure on the properties of microfiber nonwoven materials, bicomponent spunbond-spunlance nonwoven materials with different weights (80, 120, 160 g/m2) were prepared by bicomponent spunbond technology and spunlace technology under different hydroentangling pressures. The influences of hydroentangling pressure on air permeability, water vapor permeability, mechanical properties and filtration performance were investigated. The results showed that the thickness, mean pore size, air permeability and water vapor permeability decreased with increase hydroentangling pressure of from 15 MPa to 28 MPa at the same weight. The tensile strength increased with the increase of hydroentangling pressure and then decreased, and the elongation at break was in opposite trend. The filtration efficiency and filtration resistance increased with the increase of hydroentangling pressure. When the weight is 80 g/m2and hydroentangling pressure is 22 MPa, the filtration efficiency (paticle size of 0.85 μm) and filtration resistance were 66.8% and 25.1 Pa, respectively.
