Abstract

Melt blowing is a melt extrusion process that allows us to start with a material in resin form and obtain a final web product in one step. The fine fibers that are characteristic of this process are in the 0.1 to 15 micron range in diameter. This process was first described in the literature by Wente of the Naval Research Laboratory in 1956 [1] and the purpose of the work was to investigate the feasibility of making ultrafine fibers for evaluation as a filtermedia. Since then melt blowing has been one of the fastest growing technologies in the non-wovens area as evidenced by the numerous articles in the literature and the number of issued patents. For example, an article by McCulloch and Graham [2] illustrated the diverse use of melt blown webs which are also referred to as Blown Micro Fiber(BMF) webs.
