Description

Protective clothing for prevention of infectious diseases and manufacturing method thereof

The present invention relates to a protective suit for preventing infection and a method for manufacturing the same, and more particularly, the hat, top, and bottom are integrally connected so that there is no gap, so that the protective performance can be improved, and fine liquid or gas and viruses, etc. are transmitted It relates to a protective suit for preventing infection, which can have improved blocking performance, and a method for manufacturing the same.

Viruses of new species (mutated/mutated/malformed, etc.) of which we are not aware are appearing all over the world.

These viruses have a devastating effect on the human body, killing millions of people worldwide.

Modern people living in an environment that can bring about social chaos around the world, it is urgent to prepare a device that can first respond and respond most effectively and quickly when exposed to the risks caused by the emergence of new viruses in countries, individuals, and families. is in reality.

Protective clothing may be used as a device for preventing the inflow and outflow of viruses.

Protective clothing is used to protect workers and medical personnel from harmful substances such as fine dust, chemicals, chemicals, microorganisms, bacteria, and viruses.

These protective clothing are distributed and used at work sites to block the spread of the virus, but there is a limit to blocking the spread of the virus because it is distributed limitedly to medical personnel or paramedics who transport and treat patients suspected of having a virus or infected with the virus. can

At a time when virus transmission spreads nationwide, not only medical personnel and paramedics, but also patients suspected of having the virus or those infected with the virus, wearing protective clothing can help to block the spread of the virus.

The protective clothing according to the prior art is made in various forms, such as protective clothing, quarantine clothing, and medical clothing, depending on the place and purpose of its use.

Protective clothing includes tops and bottoms worn over the body, and a hood (cap) that covers the head.

In addition, protective equipment such as gloves, shoes (socks/overshoes) and face cover (goggles and glasses) separately manufactured from the top and bottom are worn on the hands, feet, and face that are not protected by the top and bottom, respectively. protect them

In the Republic of Korea Patent Publication No. 1990-0000043 (published on January 30, 1999), protective clothing made of a non-woven material to wrap the body of a worker has been proposed.

However, the recent corona virus has a problem that can put the wearer at risk because it can penetrate through the clothing material.
