Abstract(s)Healthcare-associated infections (HAIs) caused by the transfer of nosocomial pathogens from high-touch environmental surfaces and medical devices are responsible for significant patient morbidity, mortality and economic cost.[1] An effective cleaning and disinfection practice plays a key role in preventing cross-contaminations and spread of HAIs.[2] Traditionally, healthcare staff has used the “bucket method”, which consists of towels saturated with diluted disinfectant contained in a bucket. This method exhibits several limitations such as improper disinfectant dilution, inadequate saturation, uneven moisture distribution, unknown material compatibility and possible contamination from reusing.[3-4] Among the most effective surface disinfection methods, the nonwoven ready-to-use disinfectant wipes are increasingly accepted for decontamination of high-touch surfaces because of its convenience and reliable performance.[5] Though some research has been done on the effectiveness of commercial available disinfecting wipes in practical use.[6] Whereas their behaviour during storage remains unknown. In addition, a lower or even abolished disinfectant efficacy of the active ingredients due to their interaction with the textile materials has been also reported.[7] This project studied the ageing of the disinfecting wipes over storage time. Chloramine as a surface disinfectant and 3 commercial wiping materials of polyester, viscose, and their combination have been selected. The wipes before and after the contact with disinfectant solution were analysed by FTIR (Fourier-transform infrared spectroscopy) and DMA (Dynamic mechanical analysis).
