Melt-blown filter fabric is a kind of non-woven fabric products, with polypropylene (PP material) granules as the raw material. The general production process of melt-blown filter cloth is polymer feeding, melting extrusion, fiber formation, fiber cooling, net formation, and reinforced into cloth. The melt-blown filter fabric is called cloth because it has the appearance and certain properties of cloth. Characteristics: the fiber mesh of melt-blown filter fabric is composed of fine shorter fibers, with good fiber net uniformity and soft feeling, excellent filtration performance, and liquid absorption property.
Meltblown cloth filter with fluffy structure has a good anti-folding ability. The ultrafine fiber with a unique capillary structure increases the number and surface area of fiber per unit area so that the non-woven melt-blown cloth has good filtering and shielding, heat insulation, and oil absorption capability.
Melt-blown filter fabric mainly plays the role of isolation and filtration in masks. Due to the special manufacturing process, it can effectively prevent dust, bacteria and viruses from invading the human body, thus reducing various infections and effectively protecting human health.
Medical masks contain at least three layers of non-woven fabric, among which the melt-blown fabric filter in the middle layer is the core "heart" of the mask to realize the filtering function. Melt blown cloth filter has outstanding adsorption and filtering ability and can block the transmission of virus droplets.
Melt-blown filter fabric products are generally used in filtration materials, clothing materials, battery diaphragm materials, wipe materials, medical and health materials, etc. In addition to the spray paint and chemical industry, melt-blown filter fabric layers are mainly used to filter dust, microbes, haze, and other micron particles. So the melt-blown filter fabric is usually called the "heart" of masks by people.
