Influence of Processing Conditions on Melt Blown Web Structure: Part 1 – DCD

Abstract

We begin an effort to quantitatively measure the influence of processing conditions on the detailed structure of commercial polypropylene melt blown (MB) webs. In this paper, we report the influence of die-to-collector distance (DCD) on fiber entanglement, fiber orientation and pore structure in webs. This enabled us to quantify the influence of DCD on web structure as well as achieve greater understanding of the commercial MB process.
