Spunbond Non Woven Fabric
Spun bonding is one of the most popular methods of producing polymer-laid nonwovens. This process is based on the melt spinning technique. The melt is forced by spin pumps through a spinneret having a large number of holes. The quench air ducts, located below the spinneret block, continuously supply the conditioned air to cool the filaments. There is also a continuous supply of auxiliary room temperature air. Over the line’s entire working width, ventilator generated under-pressure sucks the filaments and mixed air down from the spinnerets and cooling chambers.
