PTFE mask film blocks PM2.5
Due to the frequent outbreaks of new respiratory diseases around the world, researchers have been prompted to develop more advanced medical masks to provide Stronger protection. This is where the polytetrafluoroethylene mask film came into being.
Melt-blown nonwoven fabric: Melt-blown nonwoven material uses high-speed hot air flow to draw the thin flow of polymer melt extruded from the die spinneret hole. This forms ultrafine fibers and is collected on the mesh curtain or roller, and at the same time bonds to itself to become a melt-blown nonwoven fabric. Spunlace nonwovens: Spunlace nonwovens spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. The resulting fabric is Spunlace nonwoven fabric.
The surface of the polytetrafluoroethylene mask membrane is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block the PM2.5. It also has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. It has high barrier efficiency, long service life, and is light and breathable. It is the future development of masks. new direction.
