Abstract

Objective: to analyze the materials used to make masks to protect against COVID-19 for use by the general population in relation to the surface, size, shape and distribution of pores by means of a microscopic study. Method: analytical study. Analyzes of fabric samples and other materials used to make masks to protect the community in general against COVID-19 were performed in an Electron Microscopy and Microanalysis Laboratory. Results: the analysis of 100% cotton and twill samples showed these two types of fabrics are an effective microbial barrier. On the other hand, tricoline and the other fabrics and materials analyzed do not offer effective barriers to protect against COVID-19. Conclusion: among the analyzed fabrics, 100% cotton has a denser weft with thicker threads and little porosity, thereby being an effective barrier to protect against infections.
