Which sterilization method is suitable for textiles, non-wovens, and paper-plastic pouches?

1. Ethylene Oxide

2. Steam

3. Dry heat

4. Radiation

The correct answer is: Steam

The method suitable for sterilizing textiles, non-wovens, and paper-plastic pouches is steam sterilization. This technique uses saturated steam under pressure to achieve sterilization, which helps in effectively penetrating the porous materials commonly found in textiles and non-wovens. Steam sterilization is particularly advantageous for these items due to its ability to remove air from the sterilization chamber, which is essential for achieving proper heat transfer and ensuring that the steam reaches all surfaces of the items being sterilized. Additionally, steam sterilization operates at relatively lower temperatures compared to other methods, making it suitable for a wide range of materials without causing damage. Unlike ethylene oxide, which requires a longer processing time and is typically reserved for heat-sensitive medical devices, or dry heat, which is less effective for porous items, steam provides a rapid and effective method for sterilization that is both efficient and safe for textiles and paper-plastic pouches. Radiation sterilization is generally used for specific items like single-use medical devices and is not typically applied to textiles or other similar materials. In summary, steam sterilization stands out as the preferred method for these types of materials due to its effectiveness, efficiency, and capacity to securely sterilize porous configurations.
