Unveiling a Sustainable Approach towards Disposable Face Mask Production
A disposable face mask, also known by other names like a medical face mask or procedure mask, is a personal protective equipment utilized by healthcare professionals that acts as a mechanical barrier that interferes with direct airflow in and out of respiratory orifices.
A sustainable approach towards disposable face mask
production is: -
The severe acute respiratory syndrome Coronavirus 2
(SARS-CoV-2) or coronavirus disease 2019 (COVID-19) was announced as a global
pandemic on 11 March 2020 by the World Health Organization (WHO). The WHO
believes that personal protection is essential to reduce the spread. One of the
leading public health standards utilized in the health care system is utilizing
personal protection equipment (PPE), such as gloves and masks, as a public
health intervention to curb disease spread.
Wearing a mask has become a standard custom in
communities, augmenting its significance in daily life. Its usage has been
widely applied in communities to respond to this pandemic, associated with the
respiratory problem.
The material properties and the engineering design
distinguish the filtration capacity and, thus, the protection level of
disposable face masks. The raw material of disposable face masks consists of
different polymeric materials that differ in their properties, such as
polyurethane, polyacrylonitrile, polystyrene, polypropylene, polyethylene, or
polycarbonate, depending on the customers’ order.
However, among the plastic polymers that are
sufficient as material for disposable face masks, polypropylene is the most
frequently used due to its low cost and low melt viscosity for easy processing.
In other production procedures, these certain polymeric materials are for
plastic product manufacturing.
Regardless of brand, face masks are generally formed
by three layers of a thin non-woven textile: an outer waterproof layer to repel
fluids, a middle filtering layer to control particles and pathogen-containing
droplets from penetrating in either direction, and an inner absorbent layer to
trap user droplets.
Non-woven fabrics have better air permeability and
filtration efficiency than woven cloth, with non-woven being less slippery. The
nonwoven fabric is created by bonding a mass of filaments together via
chemical, heat, or mechanical procedures (spun bond and melt-blown techniques)
to form smooth, porous, and extremely durable sheets. In some manufacturing
procedures, silica nanoparticles may be utilized as a filler to enhance the
material’s mechanical strength and toughness.
