High Quality 4-Ply Non Woven Disposable Respirators "refers to high-quality four layer non-woven disposable respirators, which have the following characteristics:
Structure and Material:
Multi layer protective structure: The four layer structure provides stronger protective capabilities. The functions and materials of each layer from the outside to the inside usually vary. For example, the outer layer is usually a tough non-woven fabric material that can effectively block large particles of dust, droplets, and other pollutants; There may be two layers of meltblown fabric in the middle, which has good filtering performance and can filter out small particles, including bacteria, viruses, etc; The inner layer is made of soft non-woven fabric, which is more comfortable when in contact with the skin and can absorb the moisture exhaled by the wearer, keeping the inside of the mask dry.
High quality non-woven fabric material: Using high-quality non-woven fabric material, it has good breathability and flexibility. Breathability ensures that the wearer does not feel too suffocated while breathing, while flexibility allows the mask to better fit the contours of the face, reducing the risk of air leakage.
Protective performance:
Efficient filtration capability: It has a high filtration efficiency for various particles in the air, such as dust, pollen, bacteria, viruses, etc. For example, some high-quality four layer non-woven disposable respirators can achieve a filtration efficiency of over 95%, effectively blocking harmful substances from entering the respiratory tract and providing reliable protection for the wearer.
Liquid barrier performance: Some products have undergone special treatment and have good liquid barrier performance, which can prevent liquid splashing or penetration. They are suitable for some scenarios that may come into contact with liquids, such as medical operations, laboratory work, etc.
