These masks are made up of PET needle-punched polyester cotton fabric, Meltblown Nonwoven Fabric and PP Spunbond non-woven or needle-punched cotton fabrics. Usually, the outer layer is a nonwoven fabric which undergoes waterproof treatment. The meltblown middle later consists of specially treated Meltblown Nonwoven fabric. It has extraordinary capabilities for oil absorption, shielding, filtering and heat-insulating properties. The inner layer is made up of normal nonwoven fabric.
From all the above analysis it is evident that Meltblown Nonwoven Fabric plays a key role in mask production although every mask has its own role to play.
