1. Antibacterial ability
Since it is a medical nonwoven fabric, the first criterion is the antibacterial ability. Generally, the smmms three-layer melt-blown layer structure is used. The ordinary medical non-woven fabric uses a single-layer melt-blown layer structure. Compared with the two, it must be a three-layer structure. Antibacterial ability is stronger. As for non-medical ordinary non-woven fabrics, because there is no meltblown layer, it does not have antibacterial ability.
2. Suitable for a variety of sterilization methods
