An Experimental And Analytical Investigation On The Production Of Microfibers Using A Single Hole Melt Blowing Process, Bryan David Haynes

Doctoral Dissertations

An extensive experimental investigation was undertaken to study the influence of the processing variables on the production of microfibers using a single hole melt blowing process. included: The processing variables that were investigated air jet exit velocity, polymer throughput, die air gap, die setback, polymer and air temperatures, polymer melt viscosity as expressed by ASTM Melt Flow Rate (MFR), and collection distance. Polypropylene was used for the investigation. In addition to the experimental investigation, a one dimensional single hole melt blowing analytical model was developed.

The air jet exit velocity and polymer throughput had the most influence on the average ...
