Influence of the Processing of Non-Woven Needle-Punched Materials on the Air Flow Mode

  • Published:
Fibre Chemistry Aims and scope

The air permeability of materials obtained by deformation-heat treatment of fabrics of various surface densities based on a mixture of polyester and bicomponent fibers has been studied. To assess the influence of processing modes, the parameters obtained from the mathematical description of the nonlinear dependence of the filtration rate on the pressure drop were used. Optimal processing modes have been established, the use of which ensures an increase in filtration resistance and, accordingly, the efficiency of air purification from solid impurities.
