Raw Materials for Surgical Masks

Surgical masks made by surgical mask manufacturing machine generally consist of the following materials:
The main material of the surgical mask making machine: common surgical masks are mainly composed of three layers of non-woven fabrics. The inner layer is an ordinary non-woven fabric; the outer layer is a non-woven fabric with waterproof treatment, which is mainly used to isolate the liquid sprayed by the patient; the middle filter layer is made of polypropylene meltblown non-woven fabric (some are electret treated , The electrostatic electret can improve the filtration efficiency, reduce the filtration resistance, and even improve the uniformity of the fiber network.) Other materials include metal (for nose clips), dyes, and elastic materials (for mask belts) Wait.
Which plays the main role is the main filter material PP melt blown cloth. The main performance index of the flat mask filter material is the bacterial filtration efficiency BFE, the filtration levels are: ordinary grade, BFE95 (filtration efficiency 95%), BFE99 (filtration efficiency 99%), VFE95 (filtration efficiency 99%), PFE95 (filtration efficiency 99%), KN90 (filter efficiency 90%).
Enterprises should choose the appropriate surgical mask making machine according to the type of surgical mask to be produced and consider the filtration efficiency and weight of the filter material. For example, disposable surgical masks generally choose 20g/m2 BFE95 meltblown cloth, but N95 masks generally use 40g/m2, which has a better protective effect.
When selecting a filter material supplier, you should pay attention to requesting the BFE filter efficiency report of the surgical mask making machine filter material. At present, the internationally recognized authoritative organizations are the United States NELSON (Nielsen Laboratory) and NIOSH (National Institute of Occupational Safety and Health).
In addition, if surgical masks are produced, attention should be paid to the biological compatibility of raw materials. If the supplier can provide the biological test report of the raw material (cytotoxicity, skin irritation, delayed type hypersensitivity test), it will save the time and cost of the biological evaluation of the finished mask.
