In daily life, nonwoven fabrics are not only used for making clothing lining and packaging materials, but in many cases, they are often used for processing and making medical and sanitary materials. Nowadays, nonwoven fabrics have been increasingly widely used as sterilization packaging materials in the medical industry. Since it is used for the production, processing, and production of medical hygiene materials, there must be high quality requirements. In addition, the factors that need to be considered and understood when choosing medical non-woven fabrics cannot be ignored.
Several key factors to consider when choosing medical nonwoven fabrics:
1. Effective microbial barrier, providing long-term sterile effectiveness. In China, wet testing is usually carried out using Staphylococcus aureus droplets, as well as dry testing using quartz powder mixed with spores of the black variety. Foreign testing institutions such as Nelson Laboratories in the United States and ISEGA in Europe use aerosol methods for testing. The aerosol method takes into account kinetic energy factors, posing a higher challenge to the inspection of the sterile effectiveness of packaging materials.
2. Effective sterilization factor penetration ensures thorough sterilization. Barrier and penetration are a contradiction, but good barrier should not hinder the effective penetration of sterilization factors. Because thorough sterilization cannot be achieved, maintaining the sterility of surgical instruments in the future becomes a rootless tree.
3. Good flexibility, taking into account the convenience of use. Some brands of non woven fabrics have added plant fibers to improve the feel, but it is worth noting that medical nonwoven fabrics may not be suitable for plasma sterilization. Plant fibers can adsorb hydrogen peroxide, leading to sterilization failure, and residual hydrogen peroxide may also cause occupational injuries such as burns.
4. It is non-toxic and harmless, with no residual sterilization factors, providing safety protection for both doctors and patients. This includes both the non irritating nature of the packaging material itself and the non adsorption of sterilization factors. For low temperature sterilization, all disinfectants are toxic, so it is required that packaging materials should not have a large amount of residual disinfectants.
5. Excellent mechanical strength enables safe transportation of the surgical bag. Sterilization packages will face various external challenges during transportation, which requires medical packaging materials to have certain tensile strength, tear resistance, bursting strength, and wear resistance to meet environmental or operational challenges.
When choosing medical non woven fabrics, the tensile strength, flexibility, tear resistance, etc. of non-woven fabrics are important factors to consider when choosing medical nonwoven fabrics. I believe that through the detailed introduction of the above content, everyone has a new understanding and deeper understanding of the factors to consider when choosing medical non-woven fabrics!
