Disposable non woven products are widely used in our dialy life, especially disposable non woven medical products. Non-woven fabrics are used for non woven fabric products are mainly PP spun bond non woven fabric, PP melt-blown non woven fabric, ES non-woven fabric, FFP2 melt-blown non woven fabric.
Or BFE99 melt-blown nonwoven fabric. The face masks can be divided into a flat face mask, three-dimensional face mask or folding face mask including non woven surgical mask and disposable non woven face mask cup type face mask according to their appearance.
The flat non-woven face mask is one of the most widely used types in our daily work . The structure of non-woven face mask is divided into three parts. That is the outer layer that is made of PP spun bond non-woven fabric, PP melt-blown non-woven fabric and active carbon non-woven fabric are used as a filter in the interlayer. The inner layer is made of PP spun bond non-woven fabric or ES non-woven fabric etc.
The face masks with active carbon non woven fabric as sandwiches have stronger absorbability, it can adsorb various industrial waste gases effectively, such as benzene, formaldehyde, ammonia, sulfur dioxide, and various organic gases etc,
The function of the medical nonwoven mask is to prevent the mutual infection between medical staff and patients in the medical process. Generally, the mask should be soft, with good air permeability, barrier, and filtration to pathogens and dust. The surgical face masks are usually made of spun bond non woven fabric, PP meltblown non-woven fabric, composite non-woven fabric or composites with melt-blown nonwoven fabric as an interlayer. The filtering effect of the surgical face mask should be more than 90%, or even higher, so as to prevent infection.
Material characteristics of medical non-woven face mask: high strength, high-temperature resistance (long-term use at 150 C), anti-aging, ultraviolet resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, moth-proof, non-toxic.
The Scope of application of medical face masks: According to the standards and important technical requirements of various types of medical face masks, medical protective face masks are suitable for the protection of medical staff and related staff against airborne respiratory infectious diseases with high protection level.
Medical face masks are suitable for the basic protection of medical personnel or related personnel, as well as the protection against the spread of blood, body fluids and spatters during invasive operation. The protective effect of general medical masks on pathogenic microorganisms is inaccurate. They can be used for one-time health care in general environment or for the barrier or protection of particles other than pathogenic microorganisms such as pollen.
