Meltblown nonwoven fabric is the core material of masks. Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure and good anti-wrinkle ability. Ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. Can be used in the fields of air, liquid filter materials, insulation materials, absorbent materials, mask materials, thermal insulation materials, oil-absorbing materials, and wiping cloths. Meltblown cloth is the core material of masks. Medical masks and N95 masks are composed of a spunbond layer, a meltblown layer, and a spunbond layer. The spunbond layer and the meltblown layer are both made of polypropylene PP material.
Gram weight: 18g-500g
Wide: generally 160cm and 180mm (can also be determined according to customer needs)
Meltblown cloth uses high-speed hot air flow to draw a thin stream of polymer melt extruded from the spinneret of the die, thereby forming ultra-fine fibers and collecting them on the screen curtain or roller, while bonding itself to become Meltblown nonwovens.
The production process of melt blown cloth is mainly:
1. Melt preparation
4.The melt is extruded from the spinneret
5. Melt flow drafting and cooling
Meltblown cloth uses polypropylene as the main raw material, and the fiber diameter can reach 0.5-10 microns. These ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good air filtration. It is a relatively good mask material. In large, medium and small medical institutions, in areas affected by earthquakes and floods, in the high incidence season of SARS, bird flu and H1N1 virus, meltblown filter paper plays an irreplaceable role with its strong filtering performance effect.
Extruder screw and barrel are widely used in the plastic processing industry; they can used in the thermo-plasticit , thermo-set plastic , rubber, elastomer- plastic. We can design targeted screw and barrel according to the different resin grades and formula feature to meet the production and quality demand. They are applied in the plastic extrusion equipments as profile, tube, profile bar, rubber tire, conveyor belt, thin film, sheet, board, wire rod, granulation.
We can make the drawing according to your requirements,like the material, the machine, and the output,etc. And also we can do by your own drawings with our suggestions.
Dia of the meltblown machne screws will be 60 / 65 /90mm and so on.
