ENMELT BLOWN
· Melt-blown nonwoven fabric is a nonwoven fabric manufacturing method that melts thermoplastic polymers such as PP (polypropylene) and extrudes them through a nozzle.
· After the melted polymer is transferred to the metering pump through the extruder, each polymer passes through a distribution plate. Here, the crucial step is the application of high temperature and high-pressure air to the melted polymer through a nozzle. This process stretches and fines the polymer, preparing it for the next step. The polymer is then laminated on a conveyor belt and bonded with self-adhesion to manufacture a nonwoven fabric.
