METHOD FOR PRODUCING TEMPERATURE RESISTANT NONWOVENS

Temperature resistant multilayer composites, methods for making same, and articles made therefrom. The method can include extruding one or more polyolefm polymers having a MFR from less than 90 dg/min through at least one die having a plurality of nozzles to form a plurality of continuous fibers, at...

Zusammenfassung:	Temperature resistant multilayer composites, methods for making same, and articles made therefrom. The method can include extruding one or more polyolefm polymers having a MFR from less than 90 dg/min through at least one die having a plurality of nozzles to form a plurality of continuous fibers, at least one die operating at a melt pressure from greater than 500 psi (3447 kPa) to form at least one elastic meltblown layer; adhering the at least one elastic meltblown layer to at least one extensible layer to form a multilayer composite; and at least partially crosslinking the elastic meltblown layer or the extensible layer or both.
