Spunbond and Melt Blown Technology

From INDA's Nonwoven Glossary:

Spunbond, Spunbonded
A spunlaid technology in which the filaments have been extruded, drawn and laid on a moving screen to form a web. The term is often interchanged with “spunlaid,” but the industry had conventionally adopted the spunbond or spunbonded term to denote a specific web forming process. This is to differentiate this web forming process from the other two forms of the spunlaid web forming, which are melt blown and flashspinning.
Spunbond nonwoven, Spunbonded nonwoven
A fabric formed from spunbonded process that has been bonded by one or more methods to provide fabric integrity.
Spunbond/Melt blown composite
A multiple layer fabric that is generally made of various alternating layers of spunbond and melt blown webs: SMS, SMMS, SSMMS, etc.
Melt blowing
A nonwoven web forming process that extrudes and draws molten polymer resins with heated, high velocity air to form fine filaments. The filaments are cooled and collected as a web onto a moving screen. In some ways the process is similar to the spunbond process, but melt blown fibers are much finer and generally measured in microns. Melt blowing is a spunlaid process. The term is also spelled “meltblowing.”
Melt blown nonwoven
A melt blown web that has been bonded by one or more techniques to provide fabric integrity.
Melt blown web
A web produced by melt blowing.
