New, Moderen Textiles as Wrapping Material for Sterilization

New methods for testing permeability and durability of the microbial barrier cellulosic textiles were developed. The most resistant forms of microorganisms of apathogenic bacterial endospore of the Bacilllus genus: Geobacillus stearothermophilus and Bacillus atrophaeus were used. Testing was performed after 1, 10, 20, 30 and 50 cycles of washing and sterilization under real hospital conditions. The durability of the textile microbial barrier (one layer) was tested after 1, 2 and 3 months of storage under controlled conditions. Bacterial permeability occurs in cellulosic medical textiles when they are contaminated with an extremely high quantity of aerobe bacterial spores. During the testing of microbial barrier durability, the package remained uncontaminated after 1, 2 and 3 months of storage. Medical cellulose textiles used under real hospital conditions functioned properly as a microbial barrier system after 50 cycles of washing and sterilization and 3 months of storage, as the sterilized content was not contaminated at all ; they could be used a microbe barrier system for packing in sterilization, regardless of the fact that they do not meet the standard EN 868- 02:2009 Packaging materials for terminally sterilized medical devices.
