Personal protective equipment fabric
Melt-blown fabric is the core material of masks, and melt-blown fabric is mainly made of polypropylene. There are many voids, fluffy structure, and good anti-wrinkle ability. The ultra-fine fiber with unique capillary structure adds the number and surface area of the tissue area fiber, so that the melt-blown fabric has good filterability, masking, heat insulation and oil absorption. It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorbing materials and wipe cloths. Medical masks and N95 masks are composed of spunbond layer, meltblown layer and spunbond layer.
The melt-blown fabric is mainly used for:
1. Filter material
2. Medical and health materials
3. Environmental protection materials
4. Clothing materials
5. Battery separator material
6. Wipe materials
The melt-blown fabric filter material is made of polypropylene ultra-fine fibers randomly distributed and dipped together. The appearance is white, flat, and soft. The material is slender. The random distribution of fibers provides more opportunities for thermal bonding between fibers, thus making melt-blown gas the filter material has a larger specific surface area. After high-pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency and high dust capacity.
Melt-blown fabric is the use of high-speed hot air flow to draw the thin stream of polymer melt extruded from the die orifice, thereby forming ultra-fine fibers and collecting them on the mesh curtain or drum, and at the same time bonding themselves to become melt spray non-woven fabric.
In the season of high incidence of SARS, avian influenza and H1N1 viruses, melt blown filter paper plays an irreplaceable role with its strong filtering performance.
