EXTENSIBLE NONWOVEN FACING LAYER FOR ELASTIC MULTILAYER FABRICS

Disclosed herein is a process for forming a multilayer construction, and the multilayer constructions including at least one layer of an elastic meltblown fabric, the process comprising extruding one or more polyolefm polymer (e.g., a propylene-a-olef?n copolymer) having a MFR from less than 90 dg/m...

Beschreibung
Zusammenfassung:	Disclosed herein is a process for forming a multilayer construction, and the multilayer constructions including at least one layer of an elastic meltblown fabric, the process comprising extruding one or more polyolefm polymer (e.g., a propylene-a-olef?n copolymer) 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 (3.45 MPa) to form at least one elastic meltblown fabric, and adhering the at least one elastic meltblown fabric to at least one extensible fabric.
