What is medical non-woven fabric? Medical non-woven materials, with the continuous renewal and rapid development of packaging materials for sterilized items, medical non-woven fabrics as the final packaging materials for sterilized items have continuously entered the disinfection supply centers of various types of hospitals at all levels.

1Medical non-woven fabrics are different from ordinary non-woven fabrics and composite non-woven fabrics. Ordinary non-woven fabrics do not have antibacterial properties; composite non-woven fabrics have good waterproof effect and poor air permeability, and are generally used in surgical gowns and surgical sheets; medical non-woven fabrics are made of spunbond, meltblown, and spunbond (SMS) processes. It is formed by pressing and has the characteristics of antibacterial, hydrophobic, breathable, and no lint. It is used for final packaging of sterilized items, one-time use without cleaning.

2 Quality standard requirements for medical non-woven fabrics: The medical non-woven fabrics used for the final packaging materials of sterilized medical devices should meet the requirements of GB/T19633 and YY/T0698.2 at the same time.

3 Non-woven fabrics are valid for use: the validity period of medical non-woven fabrics is generally 2 to 3 years, and the validity period of products from different manufacturers is slightly different, please refer to the application instructions. Sterile articles packaged with medical non-woven fabrics should be valid for 180 days and not be affected by sterilization methods.

4 It is advisable to add or subtract 5 grams of 50g/m2 for non-woven fabrics used for sterilization items packaging.

5 When packaging surgical instruments with medical non-woven fabrics, the closed packaging method should be used. It should be packaged by 2 layers of non-woven fabrics in 2 times. Repeated folding can form a long curved path to prevent microorganisms from being 'easy'. Into the sterilization bag, it is not possible to pack 2 layers of non-woven fabrics once.

6 After high-temperature sterilization of medical non-woven fabrics, its internal results will change, which will affect the penetration and antibacterial functions of the sterilization medium. Therefore, medical non-woven fabrics should not be used for repeated sterilization.

7 Due to the hydrophobic function of non-woven fabrics, excessive and heavy metal instruments are sterilized at high temperature, and condensed water is formed during the cooling process, which is prone to wet wrapping. Therefore, pad water-absorbing materials in the large instrument bag, properly reduce the loading capacity of the sterilizer, leave space between the sterilization bags, and appropriately extend the drying time to prevent the occurrence of wet bags as much as possible.
