| Web Collection 1 Breathable protective suit for basic protection. Suitable for
automotive, aviation, food processing, metal processing, mining, oil and gas
operations. Generally, it is hooded from head to shoulder to body, and the cuffs
and trousers are tightened. Protective suit requires effective prevention of
dust and solid particles from entering the working environment. It should be
comfortable and breathable, and not easy to dust. It has strong protection and
can block slight splashes in low-risk areas. The fabric used in this protective
suit is SMS non-woven fabric. The structural characteristics of superfine
melt-blown fiber layer and high tenacity spunbonded non-woven fabric layer in
the structure of SMS material make the material have certain hydrostatic
pressure resistance and air permeability, which form the basic isolation
performance of SMS material. Expand the full text In addition, SMS non-woven
fabrics also have barrier properties and are used in various protective suit
products, including medical protective suit, industrial protective suit,
chemical protective suit and so on. Of course, in addition to SMS non-woven
fabrics, there are also PE film composite non-woven fabrics, breathable film
non-woven fabrics and spunbonded non-woven fabric which can be used as medical
protective suit fabrics. 2 medical protective suit Medical protective suit, also
known as medical protective suit, is the work dress of medical staff, that is,
protective clothing for the body of medical workers. It is mainly used to
isolate germs, harmful superfine dust, acid solution, salt solution and
corrosive chemicals, and keep the environment clean. 3 Characteristics and uses
of medical protective suit. (1) protective suit of common PP non-woven fabric;
It is made of PP spunbonded non-woven fabric and generally weighs 35-60 GSM.
Features: breathable, dustproof, not waterproof, good tensile resistance, the
difference between the front and back is not obvious. PP spunbonded non-woven
fabrics are used for common isolation clothes, low-grade isolation clothes and
patient clothes. (2) protective suit of that film-covered non-woven fabric; The
fabric is a film-coated non-woven fabric, generally weighing 35-45 GSM. Has the
characteristics of airtightness, waterproofness, good bacteria isolation effect,
obvious distinction between the front side and the back side, non-woven fabric
on the side in contact with the body, no allergy and good hand feeling. There is
a layer of plastic film outside to prevent liquid leakage, used in pollution and
virus occasions, hospital infectious wards mainly use film-covered non-woven
protective suit. (3) SMS non-woven protective suit. There are three layers of
composite non-woven fabrics, a waterproof and bacteria-proof layer in the
middle, and a sesame point SMS non-woven fabric in the outer layer, which is
strong and tensile, and has the function of isolating waterproof and breathable.
Grams of 35-60 GSM are generally used. SMS non-woven fabrics are used for
surgical gowns, surgical hole towels, isolation gowns, test gowns, operation
gowns and non-surgical masks, as well as visitors' clothes. (4) protective suit
of that breathable film non-woven fabric. PP polypropylene is used and covered
with PE breathable film. Generally,
KN95
Mask with Fast Shipping, 30g PP + 30g PE breathable film is used. Therefore,
it has strong air permeability, good anti-permeability, and high impact
resistance while resisting the corrosion of various organic solvents and acids
and bases. Strong mechanical properties, soft and comfortable texture. Does not
support combustion, is non-toxic and non-irritating, and is harmless to skin.
Bacteria-proof, waterproof, slightly breathable, soft texture, is the most
advanced medical protective suit for medical protection. Its characteristic is
that the sweat of the human body can be emitted outward, while the harmful gases
and moisture outside can not invade. In addition, the breathable membrane
non-woven fabric is also used for surgical gowns, surgical hole towels and
isolation gowns. The chairman personally took the lead in research and
development, and the medical equipment leader broke into the 100 billion
protection market. Cypress blue apparatus Summer has come, but the novel
coronavirus has not gone. At present, there are nearly 16 million confirmed
cases of COVID-19 in the world, and the number of new cases is still more than
200,000 per day. According to the prediction of many experts,
Quickly
Delivery Disposable Protective Clothing, it is a big probability that the
global epidemic will last until next autumn. The medical protection market
activated by the epidemic will remain highly active. In this context, medical
protective products will also maintain a high consumption for a long time, and
the global market is far from saturated. 1 "Capital of Medical Consumables"
under the Epidemic Situation In the first half of the year, everyone was
interested and curious about the mask market. Not only because we need to wear
masks every day to prevent infection, but also because its price has risen and
fallen sharply in the short term, which is closely related to our daily economic
life. Strong demand determines the strong market, in the past six months, the
domestic market for protective products is almost crazy. According to the data
of Tian Eye Check, there are nearly 160,000 enterprises in China whose business
scope includes mask business. Among them, more than 70000 enterprises were newly
registered in the first half of this year, which is 12 times the number of the
same period last year. The sudden "prosperity" of the mask market has made Henan
Changyuan repeatedly "out of the circle", moving from behind the scenes to the
front stage. Changyuan is a county-level city directly under the jurisdiction of
Henan Province, known as the "capital of medical consumables" in the industry.
According to a previous report by Xinhua News Agency, Changyuan currently has
more than 70 enterprises of various types of sanitary materials, operating more
than 2000 enterprises, usually accounting for more than 50% of the national
market sales, and the coverage rate of major hospitals in the country exceeds
75%. There is a joke in the local area, "If Changyuan sneezes, the national
medical consumables market will catch a cold." It is enough to show the
important position of Changyuan in the national Eisai market. During the
epidemic in China, dealers who went to Changyuan to buy masks stood on the
street almost every day, sometimes even queuing for one or two kilometers. The
daily orders of the mask factory are like snowflakes, and the masks are pulled
away as soon as they leave the factory. Helping Changyuan City "out of the
circle" is also the city's leading enterprise Camel Holding Group Co., Ltd. The
company, whose anesthesia kits account for one third of the country's market
share, did not produce masks before the epidemic. However, the severity of the
epidemic made them realize that the shortage of protective materials was the
most prominent problem, so they set up an emergency research group to undertake
the first batch of COVID-19 pandemic prevention and control projects in Henan
Province, "rapid and residual-free sterilizat ion methods for protective
products urgently needed for the epidemic situation" and "research on new
omni-directional functional head and face protective devices", and began to set
foot in the field of medical protection. After making this decision, Camel Group
urgently launched the production line of medical protective equipment, and the
personnel of other production lines were also transferred to the production line
of protective equipment. Concentrated efforts are very effective. Camel Group
spent a total of 15 days from the independent development of moulds to the
launch of the first generation of windscreen products. Soon after the news
spread to the Internet, it became a hot search. The reading volume of Weibo
alone was as high as 310 million. The vast number of medical staff and netizens
left messages praising it, "The capital of medical consumables is really
unusual.". 2 Leading enterprises enter the market The chairman personally led
the research and development team. As the leading enterprise of medical devices
in Changyuan City, Camel Man began to enter the medical protection market during
the epidemic period,
Medical

Virus
Prevention Mask 3 Ply with Earloop, but it did not affect its rapid
occupation of a place in the market. When the epidemic in China is serious, the
primary task of Changyuan City is to expand capacity and production. Under the
guidance of this goal, the daily production capacity of local medical protective
masks in Changyuan has increased from less than one million before the epidemic
to more than 50 million. Among them, Camel's mask production capacity can reach
5 million, accounting for one tenth of the total daily production capacity. It
is not easy to achieve such capacity, especially during the shortage of raw
materials for melt-blown fabrics. At the beginning of the outbreak, the output
of melt-blown fabrics in Changyuan was only a few hundred kilograms, which
directly affected the production capacity of local medical protective equipment
enterprises in Changyuan. For many mask manufacturers, if they want to buy
melt-blown cloth at that time, they need to replace it with a mask. It's
interesting to say that the camel man bought a mask at that time, and it was
bought at a high price, but it was not used to replace the melt-blown cloth. At
that time, Wang Guosheng, chairman of Camel Group, issued instructions to the
sales department to purchase 400000 yuan worth of masks, protective suit and
other products from other enterprises at a high price through his own channels,
and sold them at a fair price or donated them directly to medical units. This
established the camel people's determination to produce their own masks. In
fact, for a long time since then, when the prices of production equipment and
raw materials have risen sharply, camel people have insisted on selling at the
bottom price even if they lose money. It is precisely because of the insistence
on this original intention that camel people decided to independently develop
melt-blown cloth machine to solve the problem of mask production. Not only that,
camel people also made 10 mask machines and 50 hot air blowers. In fact, Camel
Group only got the production qualification of medical masks on March 6, when
the mask machine equipment could not be delivered in time. It is also by virtue
of their own research and development capabilities that the camel people have
completed the task of supplying masks. As we all know, in the field of medical
protection, the highest level of protection is positive pressure protective
suit. Positive pressure means that the pressure of the gas inside the protective
suit is higher than that of the outside air, so that the virus can not easily
enter. Compared with ordinary protective suit, the design of positive pressure
avoids the problem that ordinary protective suit often have loopholes and have
no good protective effect. During the epidemic period, most of the medical staff
are equipped with ordinary medical protection, which has poor air permeability.
If the weather is hot, the stuffy feeling will be very serious. When they took
off their ordinary protective suit and showed their "scarred" faces and sweat,
Wang Guosheng, chairman of Camel Man, decided to personally lead the research
and development of positive pressure protective suit to solve the above
problems. The project team first changed the airflow channel in the protective
suit, and added a breathing valve to provide clean air by the air supply device.
The air supply volume is up to 190L/min, which is much higher than the national
standard of 120L/min, so as to ensure the real-time circulation of air in the
protective suit. Next, the air supply device will be upgraded to adjust the
temperature according to the change of seasonal temperature, which can
refrigerate and heat to achieve a certain constant temperature effect. Ordinary
medical protective suit need to be used together with goggles, surgical masks,
protective masks, protective masks and so on, while the positive pressure
protective suit changes the traditional cumbersome wearing mode to achieve
full-body protection, but does not need to be used with goggles, protective
masks and other products. At the same time, the project team tested more than 20
kinds of filter materials before and after, and finally achieved the filtration
efficiency from the initial 98% to more than 99.995%, the maximum efficiency of
isolation of pathogens. Medical positive pressure protective suit Medical
positive pressure protective hood At the same time, camel people are also
stepping up research and development of more types of masks with better
protection, including medical silicone protective masks, medical protective
masks (cup type), KN95 protective masks (fish type), net respiratory protective
masks and other products. Wherein, the medical silica gel protective mask
integrates a mask and goggles, the filtering efficiency is more than or equal to
97%, and the mask body is made of medical silica gel material, which can be
steamed and disinfected or disinfected by alcohol to realize the purpose of
repeated use. Medical silica gel protective mask More importantly, in the
research and development of new protective products, Camel Chairman Wang
Guosheng personally led the team to complete two key scientific and
technological projects undertaken by Henan Science and Technology Department in
a short period of time, developed six new products, such as new protective
hoods, positive pressure protective suit, net breathing masks, and obtained 54
patents, including 3 international patents. There are 18 utility model patents.
As a result, Camel Group has become the first licensed positive pressure
protective suit manufacturer in China. Positive pressure protective suit is at
the top of medical protective products, and its technical content is
self-evident. At present, Camel Man has a complete chain of protective products,
covering all protective products from granulation to spunbonded cloth,
melt-blown cloth production, and then to primary, secondary and tertiary
protective solutions. Production capacity and product reserves are sufficient to
meet the demand for protective products for outbreaks. 3 Overseas epidemic has
not reached its peak The protection market is far from saturated. As the
domestic epidemic subsided, the domestic medical protection market also got rid
of the crazy state, mask manufacturers turned to overseas markets, and Camel
Group was no exception. In fact, since April, the masks produced by camel people
have been mainly sold to Europe, Africa and other places. At present, the
cumulative number of overseas confirmed cases is close to 16 million, the number
of existing confirmed cases is more than 5.4 million, and the average number of
overseas newly confirmed case is more than 200000 in the past month. In this
regard, many epidemiologists have said that the overseas epidemic has not yet
reached its peak. It's hard to predict when it will end. As a major producer of
masks in the world, China accounts for half of the total production of masks in
the world. According to the research data of iMedia Consulting, it is estimated
that the total output of masks in China will exceed 100 billion by 2020, and the
output value of masks will reach 235.7 billion yuan. In combination, most of the
output value comes from overseas markets. At the same time, the demand for
medical protective suit and other products in the global market will also
increase. For global protective product manufacturers, the market is far from
saturated. In this context, the 2020 Shanghai International Epidemic Prevention
Materials and Supplies Exhibition will be held in Shanghai from July 30 to
August 1, covering masks, melt-blown cloth mask machines, protective suit,
isolation clothing, goggles and other epidemic prevention materials and
supplies, and will invite institutions and foreign trade companies, buyers,
distributors and agents from more than 80 countries to participate. Customers
include distributors, agents, import and export companies, local government
procurement of epidemic prevention materials, hospitals and so on. As one of the
leading medical equipment enterprises, Camel Group is also invited to display
its medical positive pressure protective suit, medical positive pressure
protective hood, medical silicone protective mask, medical protective hood, mask
and other products. The COVID-19 epidemic has opened up a new market for Tuoren
Group's medical protective products, especially its positive pressure protective
suit products. Camel Group also plans to use three years to compete with 3m in
the field of protection. A few days ago, Tuoren built a new city of medical
equipment industry, and established the world's production base, reserve base,
import and export base of protective products in Tuoren; at the same time,
KN95 Face Mask, it established the
research and development center, testing center and allocation center of
epidemic prevention materials. From product chain competition to industrial
clusters, it provides high-quality protection solutions for the country and even
the world. Return to Sohu to see more Responsible Editor:.
