NSTDA collaborates with the network to create “Recommendations on the characteristics of cloth face masks” for suitability for public use The Department of Science Services (Eng.), Ministry of Higher Education, Science, Research and Innovation (Higher Education, Science, Research and Innovation) has issued an announcement "Recommendations on the characteristics of cloth face masks" for suitability for use for the public. Reduce the spread of COVID-19 disease Air pollution from dust particles and reduce waste from the use of disposable masks It was created in collaboration with 10 agencies, including the Department of Medical Sciences.
Government Pharmaceutical C Level Executive List Organization Food and Drug Administration Office of the Consumer Protection Board Federation of Thai Industries Textile Industry Development Institute Thai Textile Industry Association Thai Garment Industry Association Khon Kaen University and Rajamangala University of Technology Lanna Ms. Nisakorn Jungcharoentham, Director-General of the Department of Science Services, said that there are 4 important properties to consider when choosing a cloth face mask, including number 1: “Particle Filtration Efficiency (PFE)” is the ability to Filters small dust particles from cloth face masks. How effective is it? It will indicate the quality that affects the prevention of air pollution from dust.
The efficiency of filtering particles sized 3 microns must be tested 20 times before washing and after washing, divided into 3 levels: 1. Fair dust protection, that is, the efficiency of blocking particles size 3 microns before washing is more than equal to 70% and after washing 20 times more than equal to 60%. 2. Good dust protection, that is, the efficiency of blocking particles size 3 microns before washing is more than 80% and after washing 20 times, more than 70%. 3. Very good protection against dust, that is, the efficiency of blocking particles size 3 microns before washing is more than equal to 90% and after washing 20 times more than equal to 80%. Point 2: “Water repellency” is the property of the fabric that can push water to prevent it from sticking to the surface. When water drops fall on the cloth The water will spread into droplets and will not absorb onto the fabric.
