In general, protective clothing refers to clothes worn by workers to protect the body of workers at industrial sites or to maintain a clean working environment, or clothes worn by workers to protect the human body from pathogens such as viruses in medical facilities. In particular, it is essential to wear protective clothing when entering and exiting the negative pressure ward, which is a special hospital room that is blocked to prevent pathogens spread in the air from coming out.

Protective clothing is generally composed of a top and bottom, and can be divided into those that can cover the head or not, depending on the purpose of use, but in the case of work in medical facilities or radiation facilities, to prevent infection or contamination of the head Protective clothing designed to completely cover the

Protective clothing requires airtightness to prevent infection or contamination, and for this purpose, the fabric of the protective clothing is usually made of a material that does not allow outside air to pass through. In addition, overshoes (boots) or gloves are worn on the arms and legs to prevent outside air from entering the protective clothing. However, due to this, there is a problem in that the temperature and humidity in the protective clothing increase and the body heat and sweat are not discharged, increasing the risk of safety accidents and easily lowering work efficiency. These problems are more pronounced in summer.
