The melt-blown nonwoven fabric industry is mainly used for air purifiers, as sub-efficient and efficient air filters, and for coarse and medium-efficiency air filtration with larger flow rates. It has advantages such as low resistance, high strength, excellent acid and alkali resistance, corrosion resistance, stable efficiency, long service life, and low price. The purified gas does not have the phenomenon of short fiber shedding in the filter material. The dustproof masks made of melt-blown nonwoven fabric have small breathing resistance, high dustproof efficiency of up to 99%, and are widely used in hospitals, food processing, mines and other workplaces that require dust and bacteria prevention. The anti-inflammatory and analgesic films made from special processing of melt-blown nonwoven fabric products have good air permeability, no toxic side effects, convenient use, and SMS products which are combined with spunbond fabrics are widely used in the production of surgical gowns, caps and other sanitary products.
Various oil-absorbing materials made of polypropylene melt-blown fabrics can absorb up to 14 to 15 times their own weight of oil. They are widely used in environmental protection projects and oil-water separation projects. In addition, they can be used as clean materials for oil and dust in industrial production. These applications fully utilize the characteristics of polypropylene itself and the adsorption of ultra-fine fibers made by melt-blown. In the fight against the epidemic, melt-blown nonwoven fabric has demonstrated outstanding protective and isolation functions, and has won a new recognition and favor in the market. It will usher in a round of large-scale increase.
Since the composite materials of melt-blown nonwoven fabric and spunbond fabric have high hydrostatic pressure resistance, good air permeability and filtration effect, especially the materials compounded with film have good barrier properties, and the filtration efficiency for non-oily particles can reach more than 99%. For example, medical protective clothing made of composite materials with a quantitative specification of 60 to 100g/m 2 can effectively block microorganisms, particles and fluids, and have a good protective effect against viruses such as SARS (size 45nm) and HIV (size 90nm).
Melt-blown nonwoven fabric is also an excellent wiping material, which can be used for cleaning and wiping precision instruments and equipment, and can also be used as a household cleaning cloth. In order to prevent fiber shedding during use and affect use, low-temperature hot rolling processes are often used to increase the surface strength of the melt-blown fabric. Melt-blown nonwoven fabric is an excellent sound insulation and cushioning material, which is widely used in the construction and automobile manufacturing fields.
