Melt spraying process is adopted to produce melt spraying cloth, the equipment mainly includes: screw extruder, melt pump, net changer, melt spraying device, winding device machine, air system (hot fan and heater), etc. The function of the screw extruder is to melt the slicing material; Melt pump its role is: metering, control the output and fiber fineness, melt continuous uniform delivery to the spinneret. The function of the mesh changer is to filter out the impurities in the melt so as not to block the spinneret hole. The role of the winding device machine is: melt spray cloth into a roll packaging. The function of the air system (hot fan and heater) is to provide the temperature and pressure of the hot air used in the spinning flow during the stretching. Melt-spraying cloth is the core material of the mask. The melt-spraying cloth mainly USES polypropylene as the main material. The diameter of the fiber can reach 1 ~ 5 microns. The microfiber with unique capillary structure increases the number and surface area of the fiber per unit area, so that the melt spray cloth has good filtering, shielding, thermal insulation and oil absorption. PP melt-sprayed non-woven fabric: a kind of microfiber non-woven fabric, mainly used to filter micrometer particles such as dust, microorganism and haze, can be called the "heart" of masks. After high voltage electret electrostatic treatment, with low resistance, high efficiency, high dust and other characteristics.
