At present, the common non-woven fabrics in the market can be divided into two categories, one is ordinary non-woven fabrics, and the other is medical non-woven fabrics. Because they are mainly used in medical treatment, there are strict requirements for quality. In addition, what are the differences between the two?
1. Antibacterial ability
Since it is a medical non-woven fabric, the primary standard is the antibacterial ability. Generally, the smmms three-layer meltblown layer structure is used. The ordinary medical non-woven fabric uses a single-layer meltblown layer structure. Compared with the two-phase structure, the antibacterial ability of the three-layer structure is definitely stronger. As for non-medical ordinary non-woven fabric, because there is no melt blown layer, it does not have antibacterial ability.
2. Suitable for various 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, including pressure steam, ethylene oxide and hydrogen peroxide plasma. The common non-medical non-woven fabric can not be applied to a variety of sterilization methods.
3. Quality control
Medical non-woven fabrics need to pass the certification of the relevant product quality control system. In the production process, there are strict standards and requirements for each step of the product.
The main differences between medical non-woven fabrics and ordinary non-woven fabrics are mainly reflected in these aspects. Each of them has its own use and characteristics, so long as they are correctly selected according to the demand in use.
