Objective: To analyze the fibers and porosity of Spunbond-Meltblown-Spunbond and Non-Woven Fabric materials used to manufacture surgical masks for respiratory protection of healthcare workers exposed to chemical and biological occupational hazards. Method: Descriptive analytical study, using scanning electron microscopy to analyze the materials. Conducted at the Electron Microscopy and Microanalysis Laboratory. Masks made with Spunbond-Meltblown-Spunbond wraps for sterilization and Non-Woven Fabric surgical masks were used in this research. Result: The mask made with Spunbond-Meltblown-Spunbond presents fibers distributed randomly — the inner filtering layer has fine fibers ranging from 1 to 5 μm and are well tangled. The Non-Woven Fabric mask has the filtering layer consisting of fine fibers and is less dense. Conclusion: The results of this study indicate variation in pore size and fibers of Spunbond-Meltblown-Spunbond and Non-Woven Fabric, which may result in improper filtering of chemical particles by fabric fibers. Microorganisms can vary from 1 to 5 μm, making these analyzed materials act as a protective barrier against biological risks.
