5” can be seen everywhere, and there are various models such as anti-particulate type, anti-formaldehyde type and activated carbon type. At present, most of the masks on the market are air filter masks.Masks can be generally divided into two categories: air filter masks and air supply masks. At the same time, activated carbon itself is also a source of particulate matter, which is likely to be inhaled by the wearer.
In addition, there are many multi-functional masks such as sun masks, UV masks, cartoon masks and riding masks. Air-supply mask refers to a clean air source that is isolated from harmful substances. It is sent to the person's face through a tube and a mask for breathing through power effects such as an air compressor and a compressed gas cylinder device. For those suffering from chronic respiratory diseases or frailty, it will cause a hazard. Not only can not protect PM2.
Dust mask: It is mainly dustproof and useful for blocking larger particles, but for Airlaid Paper Factory particles with a diameter of less than 5 microns, the blocking effect is limited and the antibacterial function is general.5, breathable Sex is also relatively poor, chemical fiber fabrics will also stimulate bronchial tubes, skin allergies, nose discomfort and other symptoms.3UM in the air. PM2. Surgical mask: made of three-layer non-woven fabric, suitable for operating room environment; can block particles with a diameter of about 4 microns or more. ,
. Masks under the banner of “PM2.5 mask: Effectively resist PM2. However, at present, the PM2. The performance of the mask is also different due to different filter materials.5 particle intrusion, effectively block bacteria and particles below 0.5 protective mask market is mixed with fish and dragons. Activated carbon mask: Adding activated carbon materials, the main role is to taste, but the respiratory resistance will increase
experts pointed out that after taking off the mask, do not put it in the bag or on the table, because it will make the mask directly contaminated with bacteria and other contaminants. For example, when walking on the street, there is generally no need to wear a mask. Try not to touch the outside of the mask when removing the mask, so as to prevent bacteria from getting into your hands, but it is best to wash your hands thoroughly after removing the mask.
In addition, it is best to have a separate small package. If the caregiver has to contact the patient (for example, to hold a sick child), minimize the time and use a mask or N95 gas mask. Experts point out that this method of wearing a mask is not correct. The general mask is valid for two years. 2. The mask should be Cover mouth, nose and chin completely. Elderly people with weak resistance or people with basic diseases usually wear masks when they go to crowded places.
Since the pandemic virus is sensitive to heat, it is safer to remove the gauze mask after boiling it with water. It is understood that medical masks have been approved for marketing as medical devices, while ordinary degreased gauze masks are not managed as medical devices. The mask hanging on the neck will become a collector of pollutants, and the dust, particles and droplets in the air will be directly received on the mask.
Experts said that healthy people do not recommend wearing masks in daily life and normal social activities. Hot water scalding is safer. When they get off, they immediately take off and put them in their pockets or bags, and continue to use them after get off work. A pair of masks should not be used for too long. At the same time, we must check the basic information of the product. In addition to the product name, specification model, manufacturer, implemented standard number, and product approval number, we must Airlaid Paper Company also pay attention to the production date and validity period.
2015-08-13 News Center Visitors: 4962 Why use non-woven fabric? »Durable and stylish »More spacious »Recyclable 'Can be reused »More convenient to use and carry »Washing »Available in a wide range of sizes and finish options Nonwovens provide specific functions such as absorption, liquid repellency, elasticity, stretchability, softness, strength, flame retardant redundancy, washing capacity, buffering, filtration, bacterial barrier and sterility.
In combination with other materials they provide products with different characteristics of the spectrum and used alone or as clothing parts, furniture, health care, engineering, industrial and consumer products. (4) Because of the special molecular structure of the oil agent, SILICONE polyester cotton contains almost no water, and it is relatively easy to produce static electricity during production. (2)
When there is no oil on the fiber, there is no antistatic agent on the fiber.3%, the lack of antistatic agent results in static electricity during production. It is also an important task. KN95 respirator suppliers (5) In addition to moisturizing the production room, the method of preventing static electricity can effectively eliminate oil-free cotton during the cotton feeding stage. Big. Because the moisture regain of polyester cotton is 0. It is precisely because of the wide application that many people will have a question, why does static electricity occur during the production of nonwoven fabrics?
The problem of static electricity during the production of nonwoven fabrics is mainly due to the low moisture content in the air when the fibers and card clothing are in contact , Can be divided into the following points: (1) The weather is too dry and the humidity is not enough. (3) The fiber oil content is low, and the relative static agent content will also generate static electricity.. Generally, the slip of the hand feels and the static electricity are proportional to the static electricity
1. Determined; the outermost layer is generally PP spunbond. The liquid particle protection filter is divided into two levels: P2 and P3.20 μm. 5L/min. BFE is a test method of Nelson laboratory in the United States. Generally speaking, different types of chemical filter boxes can prevent different types of chemical substances, such as organic, acidic, comprehensive anti-virus, ammonia, etc. P-level products are European standards. 3. Chinese national standard GB6223-86 UDC 614.
2. The particles filtered by N95 masks can be as small as 0. R series: R stands for Resistant to oil, and can be used to protect non-oily suspended particles and sweaty oily suspended particles, with a time limit of eight hours.3 microns in diameter. The inspection requirements are at least equal to the European respiratory protection FFP2 standard and the respiratory protection N95 standard. The purpose of all these is to test under such harsh conditions, if the filter material can pass the test Reaching the corresponding efficiency level, then in practical applications, it will be able to protect the health of workers more effectively. The difference with the American standard is that its detection flow rate is 95L/min, and it is dusted with DOP oil. my country's standard GB19083-2003 adopts American standards in principle.
These micropores can inhale toxic vapors and toxic gas molecules with different molecular sizes into them without escaping. The activated carbon in a good chemical filter box should be densely packed, with a small particle size and a large specific surface area, so that the anti-virus time will be long, and at the same time, it must be considered that the respiratory resistance is small and comfortable to wear.1 to 0. The American NIOSH (National Institute of Occupational Safety and Health) organization divides the mask filter materials into KN95 PARTICULATE RESPIRATOR Suppliers the following three according to the lipophilicity of the material:
1. The diameter of the DOP oil particles is the aggregated average particle diameter of 0.0 micron particles to detect the filter material at a flow rate of 32LPM ≥95%. When the carrier of some particulates is oily, and these substances are attached to the electrostatic non-woven fabric, the electrical properties will be reduced, and the fine dust will penetrate. 2. Taiwan’s CNS standard; 3. Coronavirus pneumonia (atypical pneumonia) virus has a diameter of about 0
This article is presented .5 from entering the body after wearing.As the saying goes '; autumn and winter poison fog killing knife';. The '; smog' that we can see and can't grasp; in fact, has a greater impact on the body, especially on the elderly group with high incidence of cardiovascular, cerebrovascular and respiratory diseases. How to avoid the harm caused by smog to the greatest extent? In foggy and hazy weather, it is not advisable to open the window for ventilation in the morning and evening. It is best to wait for the sun to come out before opening the window for ventilation. Drink a light diet and drink plenty of water. Influencing traffic safety. Fourth, due to the reduction of foggy sunshine, insufficient UV exposure in children, insufficient production of vitamin D in the body, the absorption of calcium is greatly reduced, and it will seriously cause infantile rickets and slow growth of children.
Second, the impact on the cardiovascular system. Long-term exposure to this environment can also induce lung cancer. Among 3-Layer Face Mask company them, the main health hazards are aerosol particles with a diameter of less than 10 microns, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, fuel and automobile exhaust, etc. Now, the deterioration of the air makes the haze weather still rampant in spring and summer.
Third, the haze weather can also lead to the weakening of the near-surface ultraviolet rays, so that the activity of infectious bacteria in the air is enhanced and the number of infectious diseases increases. It is easy to get out of control when encountering discomfort. Haze weather often appeared in autumn and winter. Cotton masks are best for masks, because some people are allergic to non-woven fabrics, and cotton masks are generally not allergic to people. This not only supplements various vitamins and inorganic salts, but also helps to eliminate lungs. At the same time, select masks that have been filtered by professional protection agencies to filter particles, such as Wuhan Longfeixiang masks The retention efficiency of 0
' Pi Xiaolin, deputy director of the Consumer Guidance Department of the China Consumers Association, is also continuing to pay attention to the introduction of this standard. To this end, enthusiastic netizens spontaneously test the anti-haze effect of different types of masks and sum up the purchase standards.
However, it is gratifying that the standard preparation work for the 'Technical Specifications for Daily Protective Masks' was held recently, and the standard setting work was officially launched, which also means that the market's lack of unified standards is expected to end. However, the experts of the Consumers Association reminded that consumers should choose according to their physical fitness,
try to choose masks produced by large enterprises, and carefully identify the implementation standards . Different production standards make consumers scratch their heads.Recently, frequent smog in Beijing, Tianjin and Hebei has attracted netizens to vomit, and they have to wear various anti-haze artifacts when they go out. Industry insiders estimate that 'a standard is subject to strict procedures, and the fastest time is 2015. He said that the introduction of the new standard will inevitably raise the entry threshold for enterprises and effectively protect the interests of consumers.
According to the 'Legal Daily' report, relevant state departments have also opened 3-Layer Face Mask company green channels to speed up the approval of the establishment of national standards, and has issued the standard plan number 20140042-T608. A recent article titled 'Is your mask correct?' The article 'Review of True and False Anti-Haze Masks' is popular on the Internet. Pi Xiaolin, deputy director of the Consumer Guidance Department of the China Consumers Association, told the Health Channel of China News that the mask production standards were previously formulated in the context of industrial production environments.
However, how to buy effective anti-haze masks in the current reality? Enthusiastic netizens have specifically tested a variety of so-called anti-haze masks and gave suggestions..
A wallpaper made of natural plant KN90 Respirator factory such as cotton and hemp is non-woven. The green non-woven fabric can be further processed into artificial skin, anti-sticking gauze, surgical coats, antibacterial coverings, disinfecting wraps, protective clothing, antibacterial cloths, masks, diapers, sanitary napkins, sanitary pads, and civilian wipes Cloths, wet facial towels, towels, soft towel rolls, beauty supplies, etc. Feel the touch: Pure paper wallpaper and non-woven wallpaper look similar, but they are very different in terms of feel. It is currently the most popular new green environmental protection wallpaper material in the world.
From the aesthetic point of view, the hot-pressed non-woven environmental protection bag is pursuing visual effects such as simplicity, clarity, strip beauty, and planarization. In terms of environmental protection, fully heat-pressed non-woven bags are more environmentally friendly, mainly because they can be completely degraded and meet the requirements of the current environmental protection bag market. After tearing, there is no fiber at all. 2. Spunlace fabric is used for personal care and environmental protection Strictly controlled surgical supplies. In terms of practicality, non-woven bags have the advantages of cleanliness, environmental protection, complete degradation, and strong aesthetics.
Combustion without smoke and smell: Non-woven wallpaper is a kind of wallpaper formed by non-woven cotton and other natural plant fibers. According to the actual use of the individual, a fully heat-pressed non-woven environmental protection bag: shopping once a week and returning to the company once on the weekend, it took about three months, and the practicality and aesthetics did not change much; I still continue to use the environmental protection bag.
The sharp increase in demand for masks has led to a rapid increase in the demand for upstream meltblown nonwoven fabrics, but it is constrained by the slow expansion of production equipment capacity and long delivery cycles, and the slow expansion of meltblown nonwoven fabrics.After the outbreak in February 2020, meltblown nonwoven fabrics Prices rose rapidly, from 20,000 yuan / ton to a maximum of 650,000 yuan / ton.
Domestic non-woven fabric face mask suppliers and central enterprises have expanded the production capacity of melt-blown non-woven fabrics to meet downstream demand, among which the non-woven fabric industry leader works overtime to produce spunlace, melt-blown and other non-woven fabrics for mask production
In addition, the production of protective clothing requires the use of spunbond non-woven fabrics, and the production of disinfectant wipes and wipes requires the use of spunlace non-woven fabrics. The increase in demand for protective clothing and disinfectant wipes after the epidemic also drove the growth of the corresponding consumption of non-woven products. Due to the abundant production capacity of spunbond and spunlace nonwoven fabrics, their prices are relatively stable.
In the long run, China's non-woven fabric demand has a large growth space. The short-term outbreak will catalyze the need for non-woven fabrics such as spunlace and meltblown.
In the long-term, China's non-woven fabric industry also has a large space for development. From the perspective of industrial structure, the processing of industrial textile fibers in European and American countries accounts for more than 40% of the textile industry. In 2018, China's industrial textiles accounted for more than 27%. The non-woven fabric industry still has great development potential in the future.
From the perspective of consumption level, due to gaps in income and consumption level, compared with developed countries, China's per capita consumption of non-woven fabrics is at a low level. The largest application area of China's non-woven fabrics is medical and health care.In 2016, the national medical and health non-woven fabric consumption was 1.461 million tons, accounting for 27.3%, while 60% to 70% of the non-woven fabrics in the U.S. market were used for Medical, health and daily necessities. In Japan, non-woven fabrics consumed by industrial, medical and sanitary products accounted for 57.4% of the demand.
Due to the high cost of use, the proportion of disposable non-woven fabric products in China is much lower than that of developed countries. Short-term epidemics increase the demand for protective products.In the long run, the consumption of medical non-woven fabrics is expected to continue to grow, driving medical non-woven fabric materials. Production enterprises are developing rapidly.
