Fabric nonwoven melt-blow

Polymer extrusion-based processes Some of the most significant contributions to the nonwoven industry came from the development of the direct polymer-to-fabric converting processes. These processes include spun-bonding, melting-blowing, and porous film. Nonwovens made by these processes are known as spunbond (SB) nonwovens, melting blown (MB) nonwovens, and apertured-fllm nonwovens.
