Why the non-woven fabric behind the mask can prevent viruses

We usually say that masks are non-woven materials. Non-woven fabrics are non-woven fabrics compared to woven fabrics. They are composed of oriented or random fibers.
1. Mask material
Non-woven fabric, also known as non-woven fabric, as the name implies, it is not traditionally interwoven and knitted together by the warp and weft of one by one yarn, but the fibers are directly bonded together by physical methods, and the top The spunbond and meltblown are the two manufacturing processes of non-woven fabrics.
Compared with those made by traditional methods, non-woven fabrics are easier to cut and sew, stronger, more durable, softer and smoother, do not produce fiber debris, and have higher production efficiency and lower cost. The most intuitive example of comparison between traditional woven fabric and non-woven fabric may be the comparison between traditional baby diapers and diapers.
2. The non-woven fabric behind the mask
This link will basically produce polypropylene non-woven materials directly used in the final production of masks, and some companies in this link will directly produce terminal mask products, such as Tianjin TEDA Clean Material Co., Ltd., a subsidiary of the listed company TEDA.
General medical masks and dust masks are mostly three-layer, divided into outer layer, inner layer, and filter layer. The outer layer and inner layer are basically spunbonded non-woven fabrics, and the filter layer is melt-blown non-woven fabrics.
Spunbond and meltblown are two common methods for producing non-woven fabrics in the medical and health field. The process flow of the two methods is basically similar. They both extrude the polymer plastic into filaments in the molten state from the spinneret holes, then lay the net, and finally use the non-traditional textile method of reinforcement (thermal bonding, self-adhesive, Chemical bonding, needle punching, spunlace, etc.) to reinforce the web into a non-woven fabric.
The layered combination of spunbond non-woven fabric and melt-blown non-woven fabric forms a composite non-woven fabric. The common medical mask above us is a three-layer composite non-woven fabric structure: SMS non-woven fabric.
