In daily life, non-woven fabrics are not only used to make clothing linings and packaging materials. In many cases, non-woven fabrics are often used to process medical and sanitary materials. Nowadays, non-woven fabrics are used as sterilization packaging materials. The medical industry has been more and more widely used. Since it is used in the production and processing of medical sanitary materials, there must be high quality requirements. In addition, factors that need to be considered and understood when choosing medical non-woven fabrics cannot be ignored.

Several factors that need to be considered when choosing medical non-woven fabrics:

1. An effective microbial barrier provides long-term aseptic effectiveness. In China, Staphylococcus aureus droplets are commonly used for wetness testing, and quartz powder mixed with spores of Bacteroides spp. for dryness testing.

Foreign testing institutions such as the Nelson Laboratory in the United States and ISEGA in Europe use aerosol methods for testing. The aerosol method takes into account the kinetic energy factor, which poses a higher challenge to the inspection of the sterility effectiveness of packaging materials.

2. The effective sterilization factor penetrates to ensure the thoroughness of sterilization. Barrier and penetration are a contradiction, but a good barrier should not hinder the effective penetration of sterilization factors. Because it is impossible to sterilize thoroughly, keeping the surgical instruments aseptic afterwards becomes a tree without roots.

3. Good flexibility, taking care of the convenience of use. Some brands of non-woven fabrics add plant fibers to improve the feel, but it is worth noting that this non-woven fabric may not be suitable for plasma sterilization. Plant fiber will adsorb hydrogen peroxide and cause sterilization failure, and residual hydrogen peroxide may also cause occupational injuries such as burns.

4. It is non-toxic and harmless, and has no residual sterilization factor, providing safety guarantee for both doctors and patients. This includes not only the packaging material itself does not have irritation, but also includes the non-adsorption of sterilization factors. For low-temperature sterilization, the sterilizing agents are toxic, so packaging materials are required not to leave a large amount of sterilizing agents.

5. Excellent mechanical strength, so that the surgical kit can be transported safely. Sterilization packages will face challenges from various external forces during transportation. This requires medical packaging materials to have a certain degree of tensile strength, tear strength, burst strength and abrasion resistance to deal with environmental or operational problems. challenge.

When choosing a medical non-woven fabric, the tensile strength, flexibility, tear strength, etc. of the non-woven fabric are all important factors that need to be considered when choosing a medical non-woven fabric. I believe everyone through the above detailed introduction, Have a new understanding and a deeper understanding of the factors that need to be considered when choosing medical non-woven fabrics!
