| Abstract: | With the outbreak of the COVID-19 pandemic, textile laundering hygiene has proved to be
a fundamental measure in preventing the spread of infections. The first part of our study evaluated
the decontamination efficiency of various treatments (thermal, photothermal, and microwave) for
bio contaminated textiles. The effects on textile decontamination of adding saturated steam into
the drum of a household textile laundering machine were investigated and evaluated in the second
part of our study. The results show that the thermal treatment, conducted in a convection heating
chamber, provided a slight reduction in efficiency and did not ensure the complete inactivation of
Staphylococcus aureus on cotton swatches. The photothermal treatment showed higher reduction
efficiency on contaminated textile samples, while the microwave treatment (at 460 W for a period of
60 s) of bio contaminated cotton swatches containing higher moisture content provided satisfactory
bacterial reduction efficiency (more than 7 log steps). Additionally, the treatment of textiles in the
household washing machine with the injection of saturated steam into the washing drum and a mild
agitation rhythm provided at least a 7 log step reduction in S. aureus. The photothermal treatment
of bio contaminated cotton textiles showed promising reduction efficiency, while the microwave
treatment and the treatment with saturated steam proved to be the most effective. |
