What is the difference between ordinary non-woven masks and disposable medical surgical masks?
Editor：Zhejiang Antipollution Medical Equipment Co., Ltd. │ Release Time：2021-12-08
The disposable medical surgical mask adopts a composite form of multi-layer non-woven non-woven fabric fiber mesh, which is composed of three filter layers: the surface anti-moisture layer, the middle high-efficiency filter and adsorption layer, and the inner skin-friendly material. It is a frameless arc. structure. The inner high-efficiency filter material uses a unique melt-blown non-woven process, and the polymer is drawn into ultra-fine fibers with an average diameter of less than 3.1um through high pressure and high heat. The fibers in the filter material are random and alternately arranged in layers. It constitutes a fibrous filter layer with multiple bending channels.
The new ultra-fine melt blown filter material has a complicated structure and three-dimensional random ordering of fibers. The material contains many tiny pores and gaps. The particles tightly surround the fibers and pass through various types of curved channels or paths, which greatly increases the suspension in the liquid. The probability of particles colliding with the mask and staying in the middle layer. This situation applies even when the particles are smaller than the fiber and the fiber gap. It is similar to shooting a mountain forest with a gun. The diameter of the shell is much smaller than the interval between flowers and trees, but the shell cannot completely penetrate the forest. The shooting ballistic is like being hit head-on. Like the liquid, it is blocked by heavy fibers and cannot penetrate.
Ordinary degreasing gauze protective masks are interlaced with warp and weft yarns. The diameter of the yarn is 0.216 mm, the warp density is 11.7 pieces/cm, and the weft density is 78 pieces/cm. The single-layer pore size is very large, and the filtration is improved by layer accumulation. Compared with the random three-dimensional structure of the ultra-fine meltblown filter material of the new medical surgical mask, the structural characteristics of ordinary gauze cannot effectively isolate and filter fine virus particles.
