The N95 mask can filter most influenza viruses, dust, pollen, smog and smoke from automobile exhaust, because the filtering efficiency of N95 mask must reach at least 95%. N represents not resistant to oil,i.e.
As the core material of medical masks, melt-blown nonwoven fabrics directly affect the protective effect of masks. There are many factors that affect meltblown fabric filtration efficiency, such as fiber linear density, fiber web structure, thickness and density.
However, as
Medical mask and N95 mask are composed of spunbond layer, meltblown layer and spunbond layer, where in both spunbond layer and meltblown layer are composed of polypropylene PP material. As the core material in the mask, meltblown cloth has a
Melt-blown cloth is a melt-blown nonwoven cloth formed by drafting the polymer melt trickle extruded from the die spinneret orifice with high-speed hot air flow, thereby forming superfine fibers and collecting the superfine fibers on a screen or roller, and
Under the influence of the new crown pneumonia, the global supply of masks is in short supply, and meltblown cloth is also rising. What are the meltblown cloth quality influencing factors as the core material of the mask? Today, through
On the evening of April 29, according to the documents issued by the China General Administration of Market Supervision, the Chinese government will focus on the supervision of masks and
Meltblown fabric is the key material for filtering in the mask and is the heart of the mask. In addition to blocking large dust particles, it can also absorb fine dust, bacteria and virus droplets through electrostatic charges on the
As the epidemic continues, the problem of China inferior mask has begun to emerge. If allowed to develop, inferior masks will bring disaster to the country and the people. Not only does it bring great potential safety hazards to the
Masks, an object that won’t be cared about by everyone at ordinary times and an unknown industry, have become a new choice for mass venture capital. There are numerous legends about making a fortune by making masks: a small mask
Meltblown fabric technology has developed rapidly, especially in recent years. With the rapid development of industry and the strengthening of environmental protection, application of meltblown fabric has become more and more extensive. The characteristics of ultra-fine fibers have been found
