G: 18 g - 500 - g Width: generally 160cm and 180cm (also depending on customer needs) Melt spraying cloth is a kind of polymer melt extruded from the nozzle hole of die head by using high-speed hot air flow to draft the thin flow, so as to form the microfiber and collect it on the screen or roller, and at the same time become the melt spraying nonwoven cloth. The production process of melt-spraying cloth is mainly as follows: 1. Melt preparation Filter 2. 3. The measurement 4. The melt is extruded through the spinneret 5. Melt trickle draft and cooling 6. Into the net Cloth of melt-blown polypropylene as the main raw material, the fiber can reach 0.5-10 microns in diameter, the capillary structure of these unique superfine fiber increased the number of fibers per unit area and surface area, thus make melt-blown fabric has very good air filterability, is relatively good mask material, in the medium, medical institutions in the earthquake, the flooding of the affected areas, in SARS, bird flu and H1N1 virus season, melt-blown filter filtering for its strong performance, play an irreplaceable role. Mainly used for: 1. Filter material 2. Medical materials 3. Environmental protection materials 4. Clothing materials 5. Battery diaphragm material 6. Wipe the material Hills has done a lot of work on the nanocrystals, which it says could be commercialised. Other companies, such as Nonwoven Technologies (NTI), he also developed and patented processes and Technologies for manufacturing nanowoven fibers. In order to spin nanofibers, the spinnerets are much smaller than the spinnerets on common melt spraying devices. When the size of the spinnerets is as small as 0.0635 mm (63.5 micron) or 0.0025 inch, the modular spinnerets can be combined into a total width of more than 3 meters. The resulting melt-sprayed fiber is about 500 nanometers in diameter. A thin single fiber can be up to 200 nanometers in diameter. Due to the small holes, if no measures are taken, the output of the melt spraying equipment for spinning nanofibers will be greatly reduced. Therefore, NTI adopts to increase the number of holes in the spinnerets, and each spinneret has 3 or more rows of spinnerets. By combining many unit components (depending on the width), the output can be greatly increased during spinning. The actual situation is that when 63.5 micron holes are used, the number of holes in a single row of spinnerets per meter is 2880. If three rows are used, the number of holes in a spinnerets per meter can reach 8640, so that the output can be equivalent to the spinning of ordinary fused spray fiber.
