2. "Medical surgical masks" generally have a three-layer (non-woven fabric) structure, which is composed of two inner layers of spunbond non-woven fabric professionally used for medical and health care, with a layer of filtration and antibacterial added in the middle. It is made of ultrasonic welded knots of melt-blown non-woven fabrics that are filtered up to 99.99% or above.

3. Medical masks are decomposed into three layers: the outer layer has an anti-droplet design (spunbond non-woven fabric), the middle layer is filtered (melt-blown non-woven fabric), and the inner layer is hygroscopic (spunbond non-woven fabric).
