The main perk of manufacturing nonwoven is that the process is a continuous one. It starts from the raw materials and ends in the finished fabric without any interruptions. So, no material handling is required resulting in low labor and manufacturing cost.
In this process, very fine fibers can be produced at very high production rates without using spinneret. The Melt Blown process was first introduced in the 1950s but became very popular in 1975. The annual growth of the process is 10%.
One very important nonwoven is ‘Needle Punched Nonwoven.’ The bonding among the fibers is dependent on mechanical bonding, i.e., frictional forces and fiber entanglements. The process is called ‘Needle Punching’ or ‘Needle Felting.’
Needle punched nonwoven has a high breaking tenacity and tear strength. But, as they have a low modulus and a poor extension recovery, they are only used in reinforcements where extension control is necessary.
