At present, the common types of non-woven fabrics on the market can be mainly divided into two types, one is ordinary non-woven fabrics, and the other is medical non-woven fabrics. Because they are mainly used in medical treatment, they have strict quality requirements. Besides, what are the differences between the two?
- Antibacterial ability
Since it is a medical non-woven 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.
- Suitable for a variety of sterilization methods
Since it has antibacterial ability, it also needs corresponding sterilization ability. High-quality medical non-woven fabrics can be applied to a variety of sterilization methods. There are three common sterilization methods: pressure steam, ethylene oxide, and hydrogen peroxide. However, ordinary non-medical non-woven fabrics cannot be applied to various sterilization methods.
- Quality control
Medical non-woven fabrics all need to pass the certification of the relevant product quality control system, and there are strict standards and requirements for each step of the product in the production process.
The main difference between medical non-woven fabric and ordinary non-woven fabric is mainly reflected in these aspects.
