 How to distinguish between spunbond nonwovens and hot air nonwovens?

The hot air nonwoven is part of the hot air bonding (hot rolling, hot air) nonwoven fabric, and the hot air nonwoven is obtained by heating the hot air on the drying equipment after the fiber is combed, adhesive nonwoven fabric.

Spunbond non-woven fabrics: the polymer extrusion, stretching, the formation of continuous filament, the filament laying into a net, and then through their own bonding network, thermal bonding, chemical bonding or mechanical reinforcement method, into a non-woven fabric.

Hot air nonwovens and hot-rolled non-woven fabrics are not spunbond process, they are hot-bonded non-woven fabrics, their raw materials are short fibers. Spunbond nonwoven is long fiber but its raw material is plastic.
