Determination of the influence of sterilization on the properties of compresses

In this paper, the influence of moist heat sterilization and ethylene oxide sterilization on the physical-mechanical properties of compresses was investigated. The investigation was performed on commercially available samples of compresses. The resistance of cellulose to various chemical agents primarily determines the behaviour of cotton fibres under the action of various chemicals, where for use in the field of medicine (medical textiles) during sterilization there must be no change in physical- mechanical and chemical properties. In order to determine the effect of two types of sterilization on cotton fibre compresses, according to EN 14079:2008, standardized methods of textile strength in the experimental part of the paper was used. Determination of degree of polymerization with morphological characteristics determined by scanning electron microscope (SEM) were carried out as well. The results showed that ethylene oxide sterilization slightly increases the degree of polymerization (DP). This fact does not affect the safety of using the compresses, because a higher value of DP compress indicates better mechanical properties, what is necessary for their usage.
