China PP Meltblown Non-Woven Mask Filter Fabric Extrusion Making Machine

Melt-blown machine is the most core material of mask, melt spraying cloth mainly USES
polypropylene as the main material, the fiber diameter can reach 1 ~ 5 micron.The microfiber with unique capillary structure increases the number and surface area of fiber per unit area, so that the melt spray cloth has good filtering, shielding, insulation and oil absorption.Can be used for air, liquid filtration materials, isolation materials, absorption materials, mask materials, warm materials, oil absorption materials and wiping cloth and other fields.
Process of meltblown nonwoven production line
Polymer preparation --- Melt extrusion --- Metering pump --- Meltblown die head assembly --- Solution thin-flow drawing --- Fiber cooling --- Auxiliary network --- Electrostatic electret --- Reinforced finished product
Melt-blown cloth is produced by melt-blown process. The equipment mainly includes: screw extruder, melt pump, screen changer, melt-blown device, winding device, air system (hot air blower and heater), etc. The function of the screw extruder is to melt the slice material; the role of the melt pump is to accurately measure, control the output and the fineness of the fiber, and continuously and evenly transfer the melt to the spinneret. The function of the screen changer is to filter out impurities in the melt so as not to block the spinneret holes. The function of the winding device is to pack the meltblown cloth into rolls. The function of the air system (hot air blower and heater) is to provide the temperature and pressure of the hot air used in the drawing of the spinning air stream.

Working principle of pp melt blown filter cartridge making machine

Polypropylene PP material through the feeding machine into a single screw extruder to squeeze out the polymer melt, through high-speed hot air or other means, the polymer by extreme stretch and form very fine short fiber, and agglomerate on the porous formation of fiber network, and finally through its own bonding and strengthening to form non-woven fabric, finally produce melt spray cloth.
