    Abstract

    Predictions of the properties of meltblown polymer nonwovens require knowledge of the angular fiber distribution in lay-down, as well as the deposited mass distribution. In the present work these two important characteristics are predicted using our previously developed model describing multiple three-dimensional viscoelastic polymer jets in meltblowing and their deposition onto a moving screen normal to the blowing direction. The results are important for predictions of strength of meltblown nonwovens.
