Processing and Quality Control of Masks: A Review
Summary
This review examines face mask manufacturing methods, filtration mechanisms, and quality control testing procedures, covering both conventional meltblown and spunlaid techniques and newer additive manufacturing approaches.
It is clear that viruses, especially COVID-19, can cause infection and injure the human body. These viruses can transfer in different ways, such as in air transfer, which face masks can prevent and reduce. Face masks can protect humans through their filtration function. They include different types and mechanisms of filtration whose performance depends on the texture of the fabric, the latter of which is strongly related to the manufacturing method. Thus, scientists should enrich the information on mask production and quality control by applying a wide variety of tests, such as leakage, dynamic respiratory resistance (DBR), etc. In addition, the primary manufacturing methods (meltblown, spunlaid, drylaid, wetlaid and airlaid) and new additive manufacturing (AM) methods (such as FDM) should be considered. These methods are covered in this study.

Influence of the Web Formation of a Basic Layer of Medical Textiles on Their Functionality
This study tested how different combinations of spunbond and meltblown nonwoven fabric layers affect the performance of layered medical textiles used in surgical masks and gowns. The combination of processes significantly influenced filtration efficiency, breathability, and barrier properties. Optimizing layered nonwoven structures is important for ensuring both safety and comfort in medical protective equipment.
A Novel Face Masks and it’s Utility during COVID-19 Pandemic: A Comprehensive Review
This review examines the technical specifications, materials, and engineering advances of face masks used during the COVID-19 pandemic, including both commercial and homemade options. Researchers discuss the environmental impact of disposable masks, noting that their widespread use has contributed to microplastic pollution as mask materials degrade. The study highlights the need for mask designs that balance effective viral protection with reduced environmental contamination.
An overview of filtration efficiency through the masks: Mechanisms of the aerosols penetration
Researchers reviewed how different types of face masks filter airborne particles — including viral droplets and pollution aerosols — examining the physical and chemical mechanisms that govern how tiny particles penetrate mask layers under varying environmental conditions. The review finds that no single mask design is optimal for all aerosol sizes and conditions, and that better filtration requires understanding the interplay of particle size, humidity, and mask construction.
Different Type of Face Masks and Their Protection Against Covid-19
This review examined the protective effectiveness of different face mask types against COVID-19. While focused on masks as infection control, surgical and N95 masks are a significant source of microplastic fibers released into the environment during use and disposal.
