Nonwovens

Synthetic Nonwovens Spunbond

Johns Manville synthetic spunbond nonwovens are made by spinning continuous polyester fibers onto a moving belt.  The continuous fibers come from polyester raw material that has been dried, melted and extruded into a flowing polymer melt.  After the spinning process, the polyester emerges as several thin, continuous filaments.  These are cooled, stretched and solidified to consistent dimensions before being laid on the belt to form a mat.

Depending on your requirements, we have the ability to vary our bonding technologies.  Our nonwovens can be bonded thermally, mechanically or chemically - each process resulting in highly differentiated characteristics.
