Abstract
A system and process for making a polymeric fibrous material having increased beta content is provided herein. The system is configured for meltblowing polymer into a fibrous material having high beta crystalline content and has an extruder for melting and moving a polymer to a meltblowing die. The meltblowing die has a longitudinally extending die tip with a plurality of spinnerets substantially equidistantly spaced from each other and a longitudinal fluid material flow through passage disposed along each longitudinal side of the die tip configured to axially attenuate the melted polymer from the die tip in fibrous form. A plurality of liquid spray nozzles are configured and disposed to spray a liquid into the fibrous melted polymer attenuated from the die tip.
