Meltblown Fabric for Face Mask Structure    It needs to be recognized that home melt-blown non-woven fabric has been pretty niche, with an annual manufacturing capability of 53,500 tons, accounting for 1% of the non-woven manufacturing capacity. They are generally used to produce masks, environmentally pleasant materials, clothing, battery separators, and different products. Non-permanent growth is slow. This is ordinarily due to the trouble of lengthy shipping cycle of manufacturing gear and excessive technical necessities for personnel operation. It is challenging to shortly extend the manufacturing ability of melt-blown fabric in a quick time.    Melt-blown cloth, the full title of melt-blown non-woven fabric, is a key cloth for bringing virus filtering impact to masks. It has ultra-fine fibers with static electricity. In addition to blocking off large dirt particles, it can additionally appeal to satisfactory dust, micro organism, and viruses via the stati...

The N95 face mask - How Long Time To Change It? Most N95 face masks are disposable consumables, especially when used to prevent infections caused by viruses, bacteria, fungi and other pathogens in the air. N95 masks should not be used for a long time, otherwise pathogens may accumulate and multiply on the surface of the mask, and eventually the inner surface of the mask will be contaminated and the disease prevention efficiency will be greatly reduced. This is slightly different from anti-fog and industrial dust inhalation, the latter case can be worn for a longer time. A few days ago, the China Food and Drug Administration's public account reprinted the "Extended Use and Reuse of N95 Masks" by IPEM (International Pharmaceutical Engineering Management). The National Institute of Occupational Safety and Health (NIOSH) said:N95 masks can be reused as long as they "maintain their structural and functional integrity and the filter material has not been physically...

Introduction of Melt blown Fabric for Face Mask

Introduction of Melt blown Fabric for Face Mask It should be known that domestic melt-blown non-woven fabrics were relatively niche, with an annual production capacity of 53,500 tons, accounting for 1% of the non-woven production capacity. They are mainly used to produce masks, environmentally friendly materials, clothing, battery separators, and other products. The short-term expansion is slow. This is mainly due to the limitation of the long delivery cycle of production equipment and high technical requirements for personnel operation. It is difficult to quickly increase the production capacity of melt-blown fabrics in a short time. Melt-blown cloth, the full name of melt-blown non-woven fabric, is a key material for bringing virus filtering effect to masks. It has ultra-fine fibers with static electricity. In addition to blocking larger dust particles, it can also attract fine dust, bacteria, and viruses through the static charge on the surface. Medical masks generally ad...

Know More About Three Kinds Face Mask Disposable mask The main material is non-woven fabric, and the filtering effect is slightly higher than that of cotton masks. Medical masks that do not have the words "protection" or "surgical" on the name are ordinary-level disposable medical masks.

Therefore, it is only used for the general medical environment. But it can be used for larger particles, such as dust, pollen, fly floc. Medical-surgical mask Medical-surgical masks are used for the protection of droplet isolation. Medical-surgical masks are required to be worn in infectious disease departments and fever clinics.

¿Puede la máscara con válvula de respiración ser antivirus?

¿Puede la máscara con válvula de respiración ser antivirus?      Un médico dijo en la plataforma SNS que las máscaras de válvula respiratoria no pueden usarse para prevenir infecciones virales. La razón que dio fue: "Es difícil alcanzar el nivel de protección N95 en la válvula de respiración". Esto suena razonable. Además, muchas personas ven fotos de médicos con máscaras sin válvulas respiratorias. Es natural pensar que es más seguro sin válvulas de respiración. Es una pena que esta afirmación parezca razonable, pero de hecho no tiene una base científica.     En primer lugar, no importa si se trata de la FDA de EE. UU., Los CDC o el NIOSH, la definición de máscaras N95 nunca ha excluido la "válvula de respiración". En la página de NIOSH de máscaras N95 previamente certificadas, podemos ver una gran cantidad de máscaras con válvulas de respiración. Aquí solo tomemos algunos productos de 3M como ejemplo.     En segundo lugar, los elementos de...

That’s because of surgical masks : 1. don't filter out smaller airborne particles 2.don't fit snugly on your face, so airborne particles can leak in through the sides of the mask Some studies have failed to show that surgical masks effectively prevent exposure to infectious diseases in the community or public settings. At present, the Centers for Disease Control and Prevention (CDC)Trusted Source doesn’t recommend that the general public wear surgical masks or N95 respirators to prot...

What's the Difference Between N95, KN95, and FFP2    When you search for the N95 respirators, there are many respirators such as KN95, FFP2, and KF94 that appeared in the same breath. What’s different between these respirators of different letters?    Actually, both the N95 face mask, KN95 face mask, FFP2 respirators have almost the same filtration efficiency, it means that KN95, FFP2, and KF94 are as effective as the N95 respirator mask. The main difference between these respirators is that they are tested by different nations.    The N95 mask has a full name of NIOSH-certified N95 respirator, which means these respirators are tested of 95% filtration and certified by the U.S. National Institute of Occupational Safety and Health (NIOSH). The KN95 face mask respirator is a particulate-filtering mask tested using the China criteria. The FFP2 is a filtering facepiece score of 94% filter capacity approved by Europe, and the KF94 is tested by Kore...
