Meltblown Structures Formed by Robotic and Meltblowing Integrated System: Interaction between the Fiber Diameter, Orientation Distribution and Pore Diameter of Simulated Networks and Real Webs

Abstract

Meltblown nonwovens have been produced as 2D web structures for a variety of end uses. Investigation into the development of 3D structures has resulted in a parametric evaluation of the process and its effects on the structural properties of the webs (fiber diameter, fiber orientation, and pore size distributions). The interrelationships between these structural parameters have been explored and a statistical model developed. SAS was used to develop the correlations between the structural parameters of the web. The pore diameter is found to be directly proportional to the fiber diameter and inversely related to the web anisotropy parameter. The relationship that was established for the 2D webs correlates to the relationship developed for the 3D web structures.
