The novel coronavirus was officially named 2019-nCoV in January 12, 2020. Common signs of novel coronavirus are respiratory symptoms, fever, cough, shortness of breath and dyspnea. The main route of transmission of new coronavirus is respiratory droplet transmission and contact transmission.


-In 2020, the new crown epidemic is rampant all over the world. Up to now, the number of new crown days in the United States has exceeded 400000


-The new coronavirus mutated and the infection rate increased by 70%


-Half a million people die in Europe! Europe becomes the new "epicenter" of global epidemic situation


-The number of new crown infections in the world has exceeded 80 million, and 4203 cases have been imported from outside China




Yangzhou Atlantis new materials Co., Ltd. pays attention to the development of world epidemic situation, and pays more attention to the healthy travel of each of us. Atlan believes that respiratory droplet transmission is the top priority of epidemic prevention. Wearing masks is essential for travel. Safety, ventilation and comfort are the real needs of mask wearers.


As a result, Atlan team's ingenuity, Atlan ultra-low resistance disposable protective mask came into being, the mask consists of three layers, the inner layer of composite spunbonded non-woven fabric has almost no resistance, the filter element layer 99 + meltblown cloth has ultra-low resistance, and the outer protective cloth can effectively absorb dust and odor.


Among them, the skin core composite spunbonded cloth is the support foundation of the atlas mask. The two-component composite material is heated by hot air, and the skin layer is melted and bonded. The core layer is not damaged in the bonding process, and it is anti rubbing and tensile, without fiber falling off, so it is healthy and safe.


High filtration efficiency and ultra-low resistance melt blown cloth is the key to mask performance and human experience. The melt blown cloth of Atlantis mask is produced and used by itself. The whole process quality control does not contain peroxide DTBP. The mask has been tested by an authoritative third party. Under the flow rate of 32 L / min, the filtration efficiency of 0.3 μ m particles and bacteria of Atlan adult mask is more than 95% and 99% respectively, but the resistance is less than 18 PA! It is especially suitable for sports fitness, pregnant women, the elderly and people with weak lung function; under the flow rate of 45 L / min, the filtration efficiency of 0.3 μ m particles is more than 95%, the filtration efficiency of bacteria is more than 99%, and the resistance is less than 20 PA! It is especially suitable for children with developing respiratory function.


This is the innovative presentation of material technology given by Atlantis.


Atlan ultra-low resistance disposable protective mask, health and safety, easy to wear.


Whether it's daily outing or leisure sports, you can breathe freely. Atlan mask, for elders, for friends, for children, for health and care.


In today's world, the epidemic situation is ups and downs, and there is no clue. In the face of the unknown reality, Atlan takes the small mask technology as the technical fulcrum to provide people with a more healthy life guarantee in the complicated tide of anti epidemic.


As general secretary Xi Jinping pull together in times of trouble, "we must win the battle of epidemic prevention and control as long as we have firm confidence, we can help each other in a boat, we should control scientifically and accurately."
