What are the ten aspects of medical non-woven fabrics

2020-11-11 11:04:57
With the continuous update and rapid development of packaging materials for sterilized items, medical non-woven fabrics, as the final packaging materials for sterilized items, have successively entered the disinfection supply centers of various hospitals at all levels. How to control the quality of medical non-woven fabrics, you must pay attention to these ten aspects of medical non-woven fabrics.


1. Medical non-woven fabric is different from ordinary non-woven fabric and composite non-woven fabric. Ordinary non-woven fabric does not have bacteria resistance; composite non-woven fabric has good waterproof effect and poor air permeability, and is generally used for surgical gowns and surgical bed sheets; medical non-woven fabrics use spunbond, meltblown, and spunbond (SMS) processes It is made by pressing and has the characteristics of anti-bacterial, hydrophobic, breathable, and dander-free. It is used for the final packaging of sterilized items. It is disposable and requires no cleaning.  

2. Quality standard requirements for medical non-woven fabrics(SMMS Non Woven Fabric Wholesale): The medical non-woven fabrics used for the final packaging materials of sterilized medical devices should meet the specifications of GB/T19633 and YY/T0698.2.  

3. Non-woven fabric is valid for use: the valid period of medical non-woven fabric itself is generally 2 to 3 years, and the validity period of products from different manufacturers is slightly different, please refer to the instructions for use. Aseptic items packaged in medical non-woven fabrics should have an expiration date of 180 days and are not affected by the method of sterilization.  

4. The non-woven fabric used for packaging sterilized items should be 50g/m2 plus or minus 5 grams.

5. When medical non-woven fabrics(Nonwoven SMS Factory) are used for packaging surgical instruments, a closed packaging method should be used. Two layers of non-woven fabrics should be packaged twice. Repeated folding can form a long curved path to prevent microorganisms from "easily" entering the sterilization package. Two layers of non-woven fabrics cannot be packaged once.  

6. After high-temperature sterilization of medical non-woven fabrics, the internal results will change, which will affect the penetration and antibacterial performance of the sterilization medium. Therefore, medical non-woven fabrics must not be sterilized repeatedly.  

7. Due to the hydrophobic properties of non-woven fabrics, excessive and heavy metal instruments are sterilized by high temperature, and condensation water is formed during the cooling process, which is easy to produce wet packs. Therefore, pad water-absorbing material in the large equipment package, appropriately reduce the loading capacity of the sterilizer, leave gaps between the sterilization packages, appropriately extend the drying time, and try to avoid wet packages.  

8. Special non-woven fabrics should be used for hydrogen peroxide low-temperature plasma. Medical non-woven fabrics containing plant fibers cannot be used, because plant fibers will absorb hydrogen peroxide. 

9. Although medical non-woven fabrics are not medical devices, they are related to the sterilization quality of medical devices. The quality of medical non-woven fabrics as packaging materials and the packaging methods are essential to ensure the level of sterility.  

10. Refer to the inspection report and product batch inspection report provided by the manufacturer, and check the physical and chemical properties of the medical non-woven fabric to ensure the quality of the products used.
