COVID-19 and fine dust have been major causes of respiratory diseases.
This year, the Ministry of SMEs and Startups has accelerated support for the development of technologies that can reduce fine dust. Along with the spread of COVID-19, face mask has also been included in the category of strategic technology. And the support for the prevention of respiratory diseases has been strengthened.
And a domestic company has developed Face Bio-Guard, which is an eco-friendly face mask substitute that is comfortable to breathe and harmless to the human body. Micro holes with a size of 5 micrometers are punched on a polyester material. Also, it can prevent fine dust particles and droplets which are bigger than 5 micrometers and it is more comfortable to breathe in comparison to the existing face masks that are made with non-woven fabrics.
We introduce various technologies that can prevent respiratory diseases as well as realize clean and healthy environment.[Interview_ SangJun Choi, CEO]
The polyester film we use for the Bio-Guard is an eco-friendly material that can keep the food. By processing micro holes uniformly on the film, in can filter out droplets or foreign substances as well as provide enhanced air permeability.
It is important to uniformly process micro holes with a size of less than 5 micrometers in order to block the droplets like coronavirus. Droplets are usually bigger than 5 micrometers, so we aim to uniformly process micro holes that are smaller than 5 micrometers, block the droplets to prevent infection and introduce the product to the market.[ArirangTV]_ Money Monster
