INTRODUCTION
Melt blowing is one of the most popular processes for making ultra-fine fibers on the micrometer or sub-micrometer scale. It is finding applications in an increasing number of fields, such as filtration, absorbency, hygiene and apparel. Many significant efforts have been made to better understand the technology and to improve the equipment by researchers and engineers around the world.
Wadsworth and Muschelewicz (1) reported that for a polymer throughput of 0.2 g/hole/min of PP, a significantly smaller fiber diameter was observed at a high airflow rate than at a low airflow rate. Haynes (2) showed a correlation between the average PP fiber ...
