The [url=http://www.beeda-teyouda.com/disposable-face-mask/]disposable face mask[/url] is made of more than three layers of non-woven fabrics of 28 grams; the bridge of the nose is made of environmentally friendly all-plastic strips,
does not contain any metal, and has a breathable strap, which is comfortable and especially suitable for electronic factories and daily use. Disposable masks (medical surgical masks) can prevent respiratory infections to a certain
extent, but cannot prevent haze. When purchasing, you should choose a mask with the words "medical surgical mask" clearly marked on the outer packaging. Disposable three-layer masks are made of two layers of non-woven fabrics
and filter paper; disposable three-layer masks are made of two layers of fiber non-woven fabrics professionally used for medical and health care, and a layer is added in the middle to filter and prevent bacteria up to 99%. % of the above
filter spray cloth is made by ultrasonic welding, the nose bridge is made of environmentally friendly plastic strips, does not contain any metal, and is equipped with breathable air, which is comfortable. The filtering effect of B.F.E is
as high as 99%, which is especially suitable for electronic factories; the disposable activated carbon mask is made of 28 grams of non-woven fabric on the surface, and the first layer in the middle is made of antibacterial filter paper
to filter and prevent bacteria up to 99%, which plays an antibacterial effect. , to prevent virus damage; the second layer in the middle is made of new high-efficiency adsorption and filtering materials - activated carbon fiber and
activated carbon cloth, which has the functions of anti-virus, deodorization, bacteria filtering, and dust blocking.
With the implementation of the national standard "Technical Specifications for Daily Protective Masks" (GB/T32610-2016), [url=http://www.beeda-teyouda.com/disposable-face-mask/disposable-face-mask-for-adults/]disposable
face mash for adults[/url] have standards to follow, and people will pay more attention to children's masks. As the demand for children's masks increases The number of children's masks on the market is gradually increasing,
mainly flat masks and foldable masks. These masks can be used as daily sanitary masks, but they cannot meet the protection requirements when worn in an air-polluted environment; some masks are just simple This kind of mask generally has
a relatively large breathing resistance, which is not conducive to the protection of children's respiratory system. Due to the lack of standards for children's masks, it is impossible to judge whether the children's masks on
the market are suitable for children. China's mask standards are divided into three categories: civilian mask standards, industrial protective mask standards, and medical mask standards, all of which are not applicable to
children's masks. There is also no international standard for [url=http://www.beeda-teyouda.com/disposable-face-mask/disposable-face-mask-for-children/]disposable face mask for children[/url]. Due to different concepts, European and
American countries do not recommend that children wear masks. All mask standards are suitable for industrial protection or medical protection. There is no standard for civilian masks, and there is no standard for children's masks.
Under the vigorous governance of the Chinese government, although the air environment has been greatly improved, with the public's emphasis on health, the society's expectations for the formulation of standards for children's
masks suitable for polluted environments have also increased. In the preparation of the national standard "Technical Specifications for Daily Protective Masks" (GB/T32610-2016), the China Industrial Textiles Industry
Association has a clearer understanding of how masks can achieve functional indicators and what corresponding protection is required for human breathing. It is known that some experience has also been accumulated in the compilation of
mask standards. On the basis of the previous investigation, in November 2017, the China Industrial Textiles Industry Association formally submitted an application to the National Standardization Administration to formulate the national
standard "Technical Specifications for Children's Daily Protective Masks".
Medical masks are mostly made of one or more layers of non-woven fabrics. The main production processes include meltblown, spunbond, hot air or acupuncture, etc., which have the equivalent effect of resisting liquids, filtering
particles and bacteria, which is a kind of medical protective textile. Medical protective masks are suitable for medical personnel and related staff to protect against airborne respiratory infectious diseases. It is especially suitable
for wearing when contacting patients with respiratory tract infections that are spread by air or by droplets during diagnosis and treatment activities. It can filter particles in the air and block droplets, blood, body fluids, secretion
droplets, etc. It is a one-time-use product. Medical protective masks can prevent most bacteria, viruses and other pathogens. WHO recommends that medical personnel use protective masks against particulate matter to prevent virus
infection in the hospital air.
Medical gowns are hospital gowns worn by medical professionals as personal protective equipment (PPE) in order to provide a barrier between patient and professional. Whereas patient gowns are flimsy often with exposed backs and arms,
PPE gowns, as seen below in the cardiac surgeon , cover most of the exposed skin surfaces of the professional medics. In several countries, PPE gowns for use in the COVID-19 pandemic became in appearance more like cleanroom suits as
knowledge of the best practices filtered up through the national bureaucracies. For example, the European norm-setting bodies CEN and CENELEC on 30 March 2020 in collaboration with the European Commissioner for the Internal Market made
freely-available the relevant standards documents in order "to tackle the severe shortage of protective masks, gloves and other products currently faced by many European countries. Providing free access to the standards will
facilitate the work of the many companies wishing to reconvert their production lines in order to manufacture the equipment that is so urgently needed." In the United States, medical gowns are medical devices regulated by the Food
and Drug Administration. FDA divides medical gowns into three categories. A surgical gown is intended to be worn by health care personnel during surgical procedures. Surgical [url=http://www.beeda-teyouda.com/isolation-gown/]isolation
gown[/url]s are used when there is a medium to high risk of contamination and a need for larger critical zones of protection. Non-surgical gowns are worn in low or minimal risk situations. Surgical and surgical isolation gowns are
regulated by the FDA as a Class II medical device that require a 510(k) premarket notification, but non-surgical gowns are Class I devices exempt from premarket review. Surgical gowns only require protection of the front of the body due
to the controlled nature of surgical procedures, while surgical isolation gowns and non-surgical gowns require protection over nearly the entire gown. In 2004, the FDA recognized ANSI/AAMI PB70:2003 standard on protective apparel and
drapes for use in health care facilities. Surgical gowns must also conform to the ASTM F2407 standard for tear resistance, seam strength, lint generation, evaporative resistance, and water vapor transmission. Because surgical gowns are
considered to be a surface-contacting device with intact skin, FDA recommends that cytotoxicity, sensitization, and irritation or intracutaneous reactivity is evaluated.
