COMPARING THE INFLUENCE OF PROCESSING CONDITIONS ON FIBERDIAMETER DEVELOPMENT IN MELT BLOWN WEBS

摘要

We are continuing an effort to quantitatively measure the influence of processing variables onrnthe structure of polypropylene melt blown webs. In this paper, we report experimentalrnmeasurements of the influence of die-to-collector distance, primary airflow rate, die temperature,rncollector speed and resin throughput rate on the diameter of single fibers in fully-formed webs.rnThis enabled us to quantitatively compare the influence of these processing variables on fiberrndiameter as well as achieve greater understanding of the melt blowing process.
