本技術結合熔噴與靜電紡絲製程技術，開發微奈米纖維為主體的高濾效低壓損過濾器，其特徵具有高比表面積的特性，同時提供高通量、低壓損，增加纖維對粒子攔截、慣性衝擊、擴散的機率，以提高對氣膠微粒之去除效率，所製備之精密過濾材之濾效率為99.97%壓損僅有3.8mmH20'濾材容塵量高達112.6g/m2'並結合複合不織布工程及產品設計與開發工程之能量，生產高效能微奈米纖維過濾器，使其成為具有輕薄、高濾效、低壓損、省能耗等特性之高效率HEPA空氣濾網。

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.
