This technology integrated with the meltblown and electrospun process technology, developed a filter which high filtration efficiency and low pressure drop. This main fiber diameter distribution has one scale in micrometer and another in nanometer. Then combined with the nonwoven composite engineering and product design and development engineering to manufacture a ＂high-performance micro-/ nano-fiber filter＂. The best filtration efficiency performance we observed was 99.97% and only3.8 mm H20 pressure drop under a standard operation test. Besides, compared to traditional micron fiber membrane, nano and micron fiber composite membrane also has the characteristics of the higher porosity, surface area and lower pressure drop.
