At present, the common types of non woven on the market can be mainly divided into two types, one is ordinary non woven, and the other is medical non woven. Since it is mainly used in medical fields, it has strict requirements for quality. What are the differences between the two?
1. Antibacterial ability of medical non-wovens and ordinary non-wovens
Medical non-wovens have requirements for initial contaminating bacteria (the total number of bacterial colonies ≤ 200CFU/g), while ordinary non-wovens do not have this requirement.
2. Sterilization methods of medical non-wovens and ordinary non-wovens
Since it has antibacterial ability, it also needs to have corresponding sterilization ability. High-quality medical non-woven can be applied to a variety of sterilization methods. The three common sterilization methods are pressure steam, ethylene oxide, and hydrogen peroxide. However, ordinary non-medical non-wovens cannot be applied to various sterilization methods.
3. Quality control of medical non-wovens and ordinary non-wovens
Medical non wovens 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.
