Introduction of Medical Non Woven Mask Meltblown Cloth

Nowadays, Covid-19 is causing the infection of more than 229 million people and more than . The speed of the outbreak and the number of cases has prompted the World Health Organization to announce an epidemic situation. So, breaking the chains of transmission is often proposed to slow down this spread and have time to control the situation and deal with epidemics. 3 Ply non-woven disposable face mask are considered a suitable method to protect people against respiratory viruses. There are different types of them and their efficiency of protection depends on the raw materials which are used for their fabrication.

What materials are used in mask?

The nonwoven fabrics and melt-blown are two principal parts of the masks that have an important effect on their efficiency. Nonwoven spun-bond fabrics are fibers that are bonded by chemical or physical treatment such as mechanical processing, heating, or using solvents.

Nonwoven melt-blown fabrics are porous materials that are produced in a single process of polymer fiber spinning, air quenching/drawing, and web formation. According to this porosity, melt-blown is considered as a high-efficiency filter with various applications such as air and water filtration or fabrication of medical equipment.Meltblown is made of polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. These ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability and shielding. It can be used in the fields of air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials and wiping cloths.

The melt-blown is a relatively good non-woven face mask material. In large, medium and small medical institutions, in disaster-stricken areas affected by earthquakes and floods, and in the high incidence of SARS, avian flu and H1N1 viruses, melt blown filter paper plays an irreplaceable role with its strong filtration performance.
